1. Tenergy Solla AA 1000mAh: Best Overall
Pros
- Designed specifically for solar-light use
- Anti-leak and outdoor durability claims
- UL Certified
- Supports up to 2, 000 charging and discharging cycles
- Includes a 12-month warranty and lifetime support
Cons
- 1000mAh capacity is lower than the 1600mAh and 2000mAh options
- Not a replacement for LiFePO4 batteries
- AA format only
Best for: someone who wants a purpose-built AA replacement for outdoor solar lights.
The Tenergy Solla is the most convincing all-rounder in this group because it is designed around the problems that make solar-light batteries frustrating. The product specifically addresses overcharging during long sunny periods and over-discharging during cloudy stretches. That focus matters more here than simply chasing the biggest capacity number. A solar light battery lives outdoors, where heat, cold, irregular charging, and long idle periods can matter as much as runtime.
Each cell is rated at 1000mAh and uses the AA format, making it a direct fit for many garden lights and other compatible devices. Tenergy says the cells can handle up to 2, 000 charging and discharging cycles and can power solar lights for up to five years. Those are manufacturer claims rather than guarantees for every fixture, since sunlight, charge circuitry, and the light itself still set the limits. Still, they give the Solla a stronger durability story than the 600mAh alternatives from Lightalent, Howardly, and JiajaX.
The batteries are also listed as UL Certified, made without the toxic heavy metals associated with NiCd cells, and pre-charged for use out of the box. The stated dimensions are 14.2 by 50mm. They can replace NiCd or NiMH solar batteries, but the listing specifically warns that they are not a replacement for LiFePO4 batteries. Check the original cell type before installing them.
This is not the highest-capacity AA set here. Brightown AA 2000mAh and the 1600mAh Kruta and WENJOOP options offer more capacity on paper, which can matter when a light has a demanding circuit or gets limited daylight. Tenergy instead makes the stronger case for long-term outdoor use, with anti-leak protection, weather durability, a stated 12-month warranty, and lifetime support. Anyone looking for a simple, high-capacity household AA may prefer EBL or Brightown, but solar-light owners should start here.
The right buyer is someone replacing cells across outdoor fixtures and wanting a battery designed for that environment rather than a generic rechargeable AA. If you are also planning the larger energy system around the lights, how panel output changes with shade and seasonal sunlight is useful context before blaming the batteries for short illumination times.
2. EBL Solar AA 1300mAh: Best High-Capacity General-Purpose AA
Pros
- 1300mAh capacity
- AA format works in many compatible devices
- Low-self-discharge design
- Rated to retain more than 80% capacity after three years
- Two charging methods
Cons
- Requires a full charge before first use
- Must be used in 1.2V devices
- The capacity is below the 1600mAh and 2000mAh choices
Best for: someone replacing solar-light batteries while keeping a versatile AA set for household devices.
EBL’s Solar AA is the set we would choose when one pack needs to cover more than garden lights. These are 1.2V NiMH AA batteries rated at 1300mAh, and the listing names solar lights, outdoor garden lights, mice, keyboards, remotes, toys, game controllers, and digital cameras among the compatible uses. That broader remit gives them an advantage over the 600mAh cells, which make more sense as direct replacements in modest solar fixtures.
The 1300mAh rating should provide more stored energy than a 600mAh cell when the device and charging conditions are otherwise similar. It does not automatically mean a light will run for twice as long, since the solar panel and the fixture's electronics determine how much energy reaches the battery. It is a sensible middle ground, though. The capacity is higher than Tenergy’s 1000mAh Solla while avoiding the larger capacity claims of Brightown AA 2000mAh, which the listing says is better paired with a fast charger because of its higher capacity.
EBL includes a low-self-discharge design and says the batteries retain more than 80% of their capacity after three years. It also describes an anti-leak design with an extra steel cell component, plus a stated operating range from -4°F to 140°F. Those details make this one of the more practical outdoor options in the list. The batteries can charge through a solar light or a household battery charger, although EBL recommends using a charger when sunlight is too weak to fully recharge them.
There is a little preparation involved. The cells are not fully charged for transport, so EBL recommends charging them before first use. More important, they are intended for 1.2V devices. They are not a drop-in substitute for equipment that specifically requires 1.5V alkaline batteries. That restriction applies to the category as a whole, but EBL states it particularly clearly.
Compared with WENJOOP AA 1600mAh, EBL gives up some capacity but offers more specific information about retention, leak protection, and temperature operation. Compared with Tenergy, it offers a higher capacity but lacks Tenergy’s stated 2, 000-cycle figure and warranty details. Choose EBL for a mixed household and outdoor setup where dependable compatibility matters more than choosing the biggest number on the label.
3. WENJOOP AA 1600mAh: Best 1600mAh Household Pack
Pros
- 1600mAh AA capacity
- 12-cell pack suits multiple fixtures
- Low-self-discharge design
- Solar and standard NiMH charging
- Clear compatibility guidance
Cons
- Needs a full charge before first use
- Not for 1.5V alkaline-only devices
- The listing does not state a charging-cycle figure
Best for: households replacing several AA solar-light batteries at once.
WENJOOP takes a practical approach: a 12-pack of AA NiMH cells rated at 1.2V and 1600mAh, with the capacity printed clearly enough to make the intended use obvious. That combination suits a home with several pathway lights, patio lights, fence lights, deck lights, or string lights. It is also a better fit than a four-cell pack when multiple fixtures need attention at the same time.
The 1600mAh rating places WENJOOP above EBL’s 1300mAh cell and Tenergy’s 1000mAh Solla on stored capacity. More capacity can help a light stay on longer after a full charge, but it can also demand more charging time from a small solar panel. WENJOOP explicitly supports charging through compatible solar lights or a standard NiMH charger, so a separate charger is useful when the weather has been poor or the batteries are being refreshed before installation.
Its low-self-discharge design is a good match for seasonal garden lighting. Spare cells can sit for a while without losing as much charge as a conventional rechargeable battery, although the listing still recommends a full charge before first use. WENJOOP also says the batteries may perform better after three to five regular charge-and-use cycles. That is a reason not to judge them from the first evening alone.
The compatibility warning is one of the most useful parts of the listing. These cells should be used only in devices that call for AA 1.2V NiMH rechargeable batteries. They are not suitable for 1.5V alkaline-only devices. WENJOOP also recommends replacing all the batteries in one device together and avoiding mixtures of old and new cells, different capacities, or different battery types. That is sound advice for multi-cell lights, where a weak battery can limit the whole set.
The weakness is a thinner durability specification than Tenergy, EBL, or Brightown. WENJOOP does not provide a charging-cycle figure in the supplied details, and it does not list a warranty or temperature range. Kruta AA 1600mAh 20-Pack offers the same headline capacity with more cells, while WENJOOP is easier to justify when 12 is the number of replacements needed. It is the sensible middle choice for a household that wants high-capacity AA cells and clear usage instructions.
4. Kruta AA 1600mAh 20-Pack: Best Large Pack
Pros
- 20 AA cells in one pack
- 1600mAh capacity
- Rated for up to 1, 200 recharges
- Solar and standard charging support
- Works with many household AA devices
Cons
- Ships only partially precharged
- A qualified charger is recommended when sunlight is weak
- No stated anti-leak or warranty information
Best for: someone replacing batteries across a large collection of outdoor lights.
Kruta’s 20-pack solves a very specific problem: a property with more solar lights than a typical 12-pack can cover. Each AA cell is rated at 1600mAh, enough to make this a serious replacement option rather than a low-capacity emergency cell. If several pathway lights, lawn lights, or landscaping fixtures have faded at once, having matching batteries from one pack makes the replacement process simpler.
The stated capacity is higher than EBL’s 1300mAh and Tenergy’s 1000mAh cells, and Kruta says the batteries can be recharged 1, 200 times. The listing also says they can replace 600mAh, 800mAh, and 1100mAh NiCd or NiMH AA cells. That does not override the need to check the light’s voltage and chemistry, but it indicates the intended role: replacing common rechargeable AA cells in solar fixtures.
Kruta supports two charging routes. A solar light can charge the battery in normal operation, while a standard charging unit is useful when sunlight is dim or when the cells need preparation before installation. The pack ships at about 50% charge for transport, so it should be charged first. Kruta also recommends charging the batteries every three to four months to help preserve their lifespan.
For general household use, these cells can go beyond lighting. The listing mentions remotes, wireless mice and keyboards, gaming controllers, RC remotes, and other devices. The practical limitation is that a high-capacity cell can take longer to fill through a small solar panel. If a fixture gets only weak winter sun, a proper NiMH charger gives you more control.
WENJOOP AA 1600mAh is the closer rival if 12 cells are enough, while Kruta wins when the number of fixtures is the deciding factor. Kruta AA 1600mAh 8-Pack has the same capacity in a smaller set, so it is less wasteful for a few lights. Kruta does not provide Tenergy’s anti-overcharge design, UL certification, or warranty details, but its combination of capacity and pack size makes it the most practical pick for extensive outdoor lighting.
5. Brightown AA 2000mAh: Best High-Capacity AA
Pros
- Highest stated AA capacity in this roundup
- 12-cell pack
- Rated for up to 1, 000 recharges
- Solar and standard charging
- Broad household compatibility
Cons
- Ships only 30% precharged
- Brightown recommends a fast charger for the larger capacity
- Higher capacity is not automatically better for every solar fixture
Best for: devices and lights that can make use of a 2000mAh AA cell.
Brightown’s AA cells are the capacity leaders among the AA products here. Each one is rated at 2000mAh, and the 12-pack gives enough cells for several lights or a mix of outdoor fixtures and household devices. That larger reservoir can translate to longer operation between full charges, especially in a remote, flashlight, or other device that draws more power than a small garden light.
The important catch is charging. Brightown says the batteries arrive only 30% precharged and recommends charging them before use. It also says a fast charger is a better option because of the large capacity. A small solar panel may not be able to refill a 2000mAh cell quickly after a cloudy day, so these make more sense when the fixture has adequate sunlight or when you have a standard charger available.
Brightown rates the cells for up to 1, 000 recharge cycles and lists a wide range of uses, including string lights, toys, remotes, flashlights, wireless mice, portable audio players, controllers, smart-home devices, and digital cameras. They are 1.2V NiMH batteries, so the device must be designed for that chemistry. They are not a universal replacement for every AA battery.
The higher capacity also makes this a less obvious choice for older solar lights with small panels. A 600mAh replacement may reach a useful charge more easily in a short winter day, while a 2000mAh cell has more room to fill. That is why the Tenergy Solla AA 1000mAh can be the better solar-specific choice even though its capacity is lower. Brightown is more compelling when the same batteries will move between lights and higher-drain household devices.
Against Kruta AA 1600mAh 20-Pack, Brightown offers more capacity per cell but fewer batteries and a lower stated cycle count. Against EBL, it gives up some low-self-discharge and temperature detail while gaining capacity. Choose it when runtime is the priority and you are prepared to use a suitable charger.
6. Kruta AA 1600mAh 8-Pack: Best Compact 1600mAh Set
Pros
- 1600mAh capacity
- Eight AA cells for a smaller replacement job
- Rated for at least 1, 200 recharges
- Outdoor temperature range from -4°F to 140°F
- Solar and standard charging
Cons
- Pack is too small for a large lighting installation
- No stated anti-leak protection
- A full charge may require a standard charger in weak sunlight
Best for: replacing the batteries in a handful of outdoor solar fixtures.
This Kruta set is the more focused version of the brand’s 20-pack. It contains eight AA batteries rated at 1600mAh, which is enough for a small group of lights without leaving a large surplus. The cells are designed for solar garden lights, landscaping lights, and lawn lights, but Kruta also lists remotes, mice, keyboards, controllers, and other household electronics.
The 1600mAh capacity gives these cells a useful balance between the 600mAh replacement batteries and Brightown’s 2000mAh option. Kruta says the batteries can be recharged at least 1, 200 times and can replace lower-capacity 600mAh, 800mAh, and 1100mAh NiCd or NiMH AA cells. The battery chemistry and voltage still need to match the device, so treat that as compatibility guidance rather than permission to install them in any AA compartment.
Outdoor operation is a strong point on paper. Kruta lists a working range from -4°F to 140°F and says the cells can be charged through the solar light or with a standard charger. The temperature range is helpful for fixtures exposed to winter cold and summer heat, but it does not make the battery immune to the other stresses of outdoor use. The light’s housing and charging circuit remain important.
The eight-cell format is the main reason to choose this version over the Kruta AA 1600mAh 20-Pack. If you have several dozen lights, the larger pack is more convenient. If only four to eight cells have failed, the smaller set is easier to manage. WENJOOP AA 1600mAh gives you 12 cells and clearer storage guidance, while Kruta supplies a stated 1, 200-cycle figure and temperature range.
The compromise is that the supplied details do not mention anti-leak construction, a warranty, or a low-self-discharge percentage. Buyers who leave lights outdoors through multiple seasons may prefer Tenergy’s more explicit outdoor design. This Kruta pack is best for a defined, modest replacement job where capacity and a stated cycle figure matter most.
7. Brightown AAA 1000mAh: Best AAA Option
Pros
- 1000mAh AAA capacity
- 12-cell pack
- Rated for up to 1, 200 recharge cycles
- Low-self-discharge design
- UL Certified according to the product listing
Cons
- AAA cells cannot replace AA batteries
- Ships only 30% precharged
- Brightown recommends a suitable charger for the capacity
Best for: solar lights and household devices that specifically use AAA cells.
The Brightown AAA is the clear choice when the fixture uses the smaller AAA format. It is easy to overlook size while comparing capacity, but an AAA battery cannot substitute for an AA cell simply because both are rechargeable. These are 1.2V NiMH batteries rated at 1000mAh, supplied as a 12-pack for solar lights, remotes, string lights, toys, flashlights, mice, portable audio players, and other compatible devices.
A 1000mAh rating is substantial for an AAA cell in this group. Brightown says the batteries support up to 1, 200 recharge cycles and up to five years of battery life. Actual results will depend on the fixture and charging conditions, but the stated cycle figure gives this pack a stronger long-term specification than the 600mAh AA alternatives. The low-self-discharge design is also useful for spare cells and seasonal lighting.
The batteries support solar and standard charging. Brightown says they arrive 30% precharged, so they should be charged before use, and it recommends a fast charger because of the capacity. That advice is particularly relevant when a small solar fixture has limited charging output. A compatible NiMH charger lets you start with a full set rather than waiting for several days of strong sun.
The listing includes UL certification among its specifications, but it does not provide the same solar-specific anti-overcharge explanation as Tenergy. That makes Brightown the better fit for a mixed household collection of AAA devices, while Tenergy remains the stronger AA choice for outdoor durability. It is also important not to confuse this product with the Brightown AA 2000mAh. The brands are the same, but the battery size and capacity are different.
Choose this set if the original battery is AAA and marked 1.2V NiMH. If the light takes AA cells, move to EBL, WENJOOP, Kruta, or Tenergy instead. For anyone designing a broader off-grid setup, understanding how a portable solar generator handles stored energy can also help separate small lighting batteries from much larger power systems.
8. Lightalent AA 600mAh: Best Replacement-Size Pack
Pros
- 12 AA batteries
- 600mAh capacity suits many basic solar fixtures
- Solar and standard charging
- Compact stated dimensions
- Intended for outdoor solar lights
Cons
- Lower capacity than every other AA option above it
- Requires a full charge before first use
- Listing recommends using up the power before recharging
Best for: basic outdoor lights that originally used lower-capacity AA rechargeable cells.
Lightalent is not trying to win the capacity contest. Its 12 AA NiMH cells are rated at 600mAh and 1.2V, a specification that lines up with many small solar garden lights and replacement fixtures. If an older light originally used a 600mAh cell, matching that capacity can be more sensible than installing a much larger battery that the fixture’s small panel may struggle to charge.
The batteries can charge from the solar cell in the fixture or through a standard charger. Lightalent says the pack is only 30% precharged for transport, so the cells need charging before use. It also recommends using up the power before recharging and topping them up every three months to help preserve lifespan. That maintenance advice is more demanding than the low-self-discharge guidance supplied with EBL or WENJOOP.
Each battery is listed as 1.2V and 600mAh, with stated dimensions of 1.97 inches long and 0.55 inches wide. Those dimensions are useful when checking an unusual light compartment, although the AA designation remains the starting point. A battery can have the right electrical rating and still be unsuitable if the fixture’s contacts or compartment are damaged or unusually tight.
The obvious weakness is runtime. A 600mAh cell stores less energy than the 1000mAh Tenergy, 1300mAh EBL, and 1600mAh Kruta and WENJOOP options. That is not necessarily a problem for a small decorative light with a modest panel, but it makes Lightalent a poor choice when the goal is to extend illumination through a long night.
Compared with Howardly AA 600mAh, Lightalent provides the same capacity and pack size, while Howardly gives a more explicit 500-cycle figure and names several types of solar lamps. JiajaX AA 600mAh 4-Pack is better when only a few cells are needed. Choose Lightalent when matching a common lower-capacity AA solar cell is more important than maximizing runtime.
9. Howardly AA 600mAh: Best Simple Solar-Light Replacement
Pros
- 12 AA cells
- 600mAh capacity
- Supports solar and charger charging
- Rated for 500 charging cycles
- Intended for several outdoor light types
Cons
- Lower capacity than the leading AA picks
- Ships partially precharged
- The listing does not include a charger
Best for: replacing a complete set of 600mAh batteries in garden lamps and lanterns.
Howardly is a straightforward replacement set for solar lamps. It includes 12 AA NiMH batteries rated at 1.2V and 600mAh, with the product description calling out lawn lamps, string lights, bollard lights, and other solar fixtures. That direct focus makes it easy to match with an older outdoor light that already uses this size and capacity.
The 600mAh rating is enough for many decorative fixtures, but it is not intended to compete with the longer-runtime potential of a 1600mAh or 2000mAh cell. The right comparison is Lightalent AA 600mAh, not Brightown AA 2000mAh. If the original battery is 600mAh and the light has a small solar panel, maintaining the original capacity may allow the cell to recharge more readily than a larger replacement.
Howardly supports charging inside a solar lamp or with a separate charger. It is shipped with only 30% to 50% charge for transport, so it needs to be charged before installation. The listing says the batteries support 500 charging cycles and recommends recharging every three months to help extend lifespan. A charger is not included, so buyers need an existing compatible unit if the batteries cannot be charged in the fixture.
The main shortcoming is the limited amount of supporting detail. Howardly does not state a temperature range, anti-leak construction, low-self-discharge retention, or warranty. Tenergy supplies a much fuller outdoor durability story, while EBL gives more information about capacity retention and temperature operation. Howardly is therefore a functional replacement rather than the most technically documented choice.
It makes sense for someone restoring a full set of lawn or garden lights with failed 600mAh cells. Use a higher-capacity battery if the fixture and charging circuit support it and longer runtime is the priority. Choose Howardly when matching the original solar-light specification and getting 12 replacement cells matter more.
10. JiajaX AA 600mAh 4-Pack: Best Small Replacement Set
Pros
- Four AA cells for a small replacement job
- 600mAh capacity
- Stated 1.2V NiMH chemistry
- Supports solar and standard charging
- Listed as free of lead, cadmium, and mercury
Cons
- Smallest pack in the roundup
- Lower capacity than the larger AA options
- The listing states at least 500 charging cycles
Best for: replacing the batteries in one or two small solar fixtures.
JiajaX is the specialist pick for a small repair. The pack contains four AA batteries rated at 600mAh and 1.2V, which is enough to replace the cells in a couple of small garden lights without committing to a larger pack. The batteries are listed at 1.97 inches long and 0.55 inches wide, matching the stated dimensions for a standard AA-style replacement in the supplied details.
The capacity is intentionally modest. JiajaX says these cells can replace lower-capacity 100mAh to 500mAh NiCd or NiMH batteries and can be used in solar garden, landscape, and lawn lights. That makes them a sensible match for older fixtures whose charging panels were designed around small cells. They can also replace disposable alkaline batteries in compatible household devices, though the device must accept 1.2V NiMH power.
JiajaX supports charging through the solar light or a standard NiMH AA charging unit. The listing says the cells support at least 500 charge cycles and are free of lead, cadmium, mercury, and other heavy elements. It also describes the batteries as able to convert solar energy into stored electricity, which is the normal operating role of a rechargeable cell in a solar light.
The four-cell format is both the advantage and the limitation. It is convenient for a small repair, but not enough for a property with many pathway or fence lights. Lightalent AA 600mAh and Howardly AA 600mAh supply 12 cells and are better suited to a full lighting refresh. If longer illumination is needed, EBL, WENJOOP, or Kruta provide more capacity per AA cell.
JiajaX is the right choice when only a few 600mAh cells have failed and the existing light uses 1.2V NiMH batteries. It is not the pick for someone trying to maximize overnight runtime or standardize a large outdoor installation. Before ordering, check the original battery marking and replace all cells in a multi-cell fixture as a set.
How to choose Best solar batteries
The right rechargeable cell is determined less by the word “solar” on the package than by the fixture’s original battery type, size, charging circuit, and available sunlight.
Battery size and voltage
AA and AAA batteries are not interchangeable, even though both appear in outdoor lighting. Check the original cell, the device label, or the manual before ordering. The products here are generally 1.2V NiMH cells, while a device designed only for 1.5V alkaline batteries may not work correctly with them.
Capacity
Capacity is measured in milliamp-hours, or mAh. A higher number means the cell can store more energy, which may extend runtime between charges. It also may require more energy and more time to recharge, so a 2000mAh Brightown cell is not automatically a better match for a small solar panel than a 600mAh Lightalent or Howardly cell.
Charging compatibility
A compatible solar light can usually charge the replacement cell in place, but weak winter sunlight or several cloudy days may leave a high-capacity battery undercharged. A standard NiMH charger is useful for initial charging and maintenance. Do not use a charger intended for a different chemistry.
Match the battery to the light’s charging circuit first, then choose the capacity that the available sunlight can realistically refill.
Outdoor durability
Outdoor cells face heat, cold, moisture, and irregular charging. Tenergy lists anti-leak protection, seasonal durability, and a design intended to address overcharging and over-discharging. EBL lists an operating range from -4°F to 140°F. Those details are more meaningful for exposed fixtures than a large capacity number alone.
Self-discharge and storage
Low-self-discharge batteries are useful when lights are seasonal or when spare cells sit unused. EBL says its batteries retain more than 80% capacity after three years, while WENJOOP describes a low-self-discharge design and recommends a few charge-and-use cycles after storage. Store batteries as directed and recharge them periodically when the listing calls for it.
Pack size and replacement method
Replace the cells in a multi-battery fixture as a complete set. Mixing old and new batteries, different capacities, or different chemistries can lead to uneven performance. A four-pack such as JiajaX suits a small repair, while Kruta’s 20-pack makes more sense when many outdoor fixtures need the same replacement.
Frequently asked questions
Can rechargeable AA batteries be used in solar lights?
Yes, if the light is designed for a compatible AA rechargeable battery, usually a 1.2V NiMH cell. Check the original battery marking before installing a replacement. A battery designed for a different chemistry or voltage may not charge or operate correctly.
Is a higher mAh rating always better for solar lights?
No. A higher mAh rating provides more stored energy, but it can also take longer to recharge through a small solar panel. A 600mAh cell may be a better match for a basic decorative light, while a 1300mAh, 1600mAh, or 2000mAh cell can suit a fixture with stronger charging capability.
Can these batteries be charged with a normal battery charger?
The listed products support charging with a compatible standard NiMH charger. Check that the charger accepts the correct battery size and chemistry. Brightown recommends a suitable faster charger for its higher-capacity batteries.
Should solar batteries be fully charged before installation?
Yes. Several products in this roundup ship only partially charged for transport. Fully charging the cells before installation gives the light a proper starting point and avoids confusing a partial initial charge with poor performance.
How often should rechargeable solar-light batteries be replaced?
There is no single replacement schedule. Battery life depends on charge cycles, weather, sunlight, the light’s charging circuit, and how deeply the cells discharge. The products list different cycle or service-life claims, but a battery that produces noticeably shorter illumination should be checked or replaced.
Can AA solar batteries replace alkaline AA batteries?
Only when the device is compatible with 1.2V NiMH rechargeable batteries. The WENJOOP listing specifically warns against using its cells in 1.5V alkaline-only devices. Check the label or manual instead of assuming every AA compartment accepts every AA chemistry.
The bottom line
The Best solar batteries in this roundup are the Tenergy Solla AA 1000mAh for outdoor durability and the EBL Solar AA 1300mAh for a versatile mix of solar lights and household devices. Tenergy has the clearest solar-specific design, while EBL combines useful capacity with low-self-discharge, anti-leak, and temperature details.
Choose WENJOOP AA 1600mAh or Kruta AA 1600mAh 20-Pack when several fixtures need higher-capacity cells, and choose Brightown AAA 1000mAh when the light specifically uses AAA batteries. For older fixtures with small charging panels, the 600mAh Lightalent, Howardly, and JiajaX cells may be the more appropriate match.
If you are undecided, read the original battery marking first, then choose the largest capacity that the light’s solar panel can realistically recharge.
