An aging Apple Watch usually fails in one of three ways: the battery barely lasts, the display stops responding, or the outer glass cracks while the LCD still works. Choosing the wrong replacement can turn a manageable repair into a watch that no longer seals or powers on.
Our Best apple watch replacement picks cover batteries for Series 4, Series 5, Series 6, and SE models, plus complete screens and a front glass lens. ASDAWN A2181 44mm Battery is the strongest all-around pick, while the rest of the range targets specific sizes and repair types.

1. ASDAWN A2181 44mm Battery: Best Overall
Pros
- Covers both Series 5 and SE 44mm models
- 296mAh Li-ion capacity
- Built-in protection against overcharging and overheating
- Repair tool parts are included
Cons
- Model confirmation is essential before opening the watch
- The listed 48-hour endurance is a claim, not a guarantee for every watch
Best for: 44mm Apple Watch Series 5 or SE owners replacing a worn battery.
The useful thing about this ASDAWN kit is its broad fit within one generation. It works with Apple Watch Series 5 44mm and SE 44mm models, so it is a sensible first pick when the watch is shutting down early but the display and touch layer are still healthy. The part is a single 296mAh Li-ion battery, and repair tool parts are included for the job.
That capacity gives the repair a clear purpose. A battery that has lost much of its original stamina can force frequent charging and make an otherwise functional watch frustrating to wear. ASDAWN says the battery can provide up to 48 hours and rates the cells for 500 cycles. Those are manufacturer claims, so actual runtime will depend on the watch, software, and battery condition.
The built-in microchip is designed to protect against overcharging, over-discharging, short circuits, and overheating. The instructions also recommend using the original charger and cable, then cycling the battery several times to reach its intended performance. That is a practical detail, although it does not remove the need for careful disassembly.
Compared with the ASDAWN A2277 40mm Battery, this model is the right choice for the larger case and has higher stated capacity. The Viimon Series 5 44mm Battery is more appealing if a printed installation manual and pre-installed adhesive matter most. ASDAWN wins here through its combination of compatibility and capacity, but it is still a delicate watch repair. Skip it if the screen is cracked, touch is unreliable, or you cannot verify the old battery model.
This is the battery we would keep for a 44mm Series 5 or SE that otherwise works normally. Before ordering, check the case size and old part number rather than relying on the watch name alone.
2. ASDAWN A2277 40mm Battery: Best 40mm Battery
Pros
- Fits Series 5 and first-generation SE 40mm models
- 245mAh Li-ion battery
- Protection against overcharging and overheating
- Repair tool kit included
Cons
- Not compatible with 44mm watches
- Battery activation guidance requires several charge cycles
Best for: owners of a 40mm Series 5 or first-generation SE with poor battery life.
The A2277 is the smaller-case counterpart to ASDAWN's 44mm battery, and that distinction matters more than the brand name. It is made for 40mm Apple Watch Series 5 and 40mm SE models. The 245mAh capacity is appropriate to that smaller housing, but it cannot be substituted for the 44mm part.
ASDAWN lists a Li-ion cell, high-speed charging, and up to 48 hours of use. Runtime claims should be treated as a ceiling rather than a promise, especially on an older watch with demanding settings or a worn charging system. The more meaningful point is that the kit is intended to restore normal battery operation without changing the watch's display assembly.
The safety features are reassuring on paper. The battery includes protection against overcharging, over-discharging, short circuits, and overheating, and the cells are described as Grade A with a claimed 500-cycle life. The product also recommends using the original charger and cable and completing 3 to 5 charge and discharge cycles before judging the battery.
This is a simpler choice than the Viimon Series 4 40mm Battery because the compatible models are newer and clearly stated as Series 5 and SE. The tradeoff is that Viimon includes a detailed installation manual and a force touch sensor flex cable for its Series 4 kit. Choose the A2277 when the watch is a 40mm Series 5 or SE, not because the two batteries look interchangeable.
The weakness is the narrow compatibility window. Anyone with a Series 4, a 44mm case, or an unverified model should skip it. For the correct 40mm watch, it is a straightforward battery-focused repair kit.
3. Viimon Series 5 44mm Battery: Best Repair Kit
Pros
- Made specifically for Series 5 44mm
- Installation manual included
- Pre-installed battery adhesive strip
- Display ring tapes and repair tools included
- 12-month warranty stated by the manufacturer
Cons
- Does not fit the 40mm version
- Narrower compatibility than the ASDAWN A2181
Best for: a first-time DIY repairer who wants the most complete Series 5 44mm kit.
Viimon's advantage is not a published capacity figure. It is the preparation around the battery. The kit is made for Apple Watch Series 5 44mm models A2093, A2095, and A2157, and it includes an installation manual, repair toolkit, pre-installed battery adhesive, and display screen ring tapes.
Pre-installed adhesive can make a meaningful difference during reassembly. A battery repair is not finished when the old cell is removed. The replacement has to sit correctly, and the display needs suitable adhesive when the watch is closed. Viimon's included materials reduce the need to source those pieces separately, though they do not make the repair risk-free.
The listing describes the battery as OEM quality and says it has multiple protection features, including safeguards against overcharging and overheating. It also describes the cell as zero-cycle. No capacity or voltage figure is provided, so this kit cannot be compared numerically with the 296mAh ASDAWN A2181. That missing figure is a limitation for readers who want to estimate runtime before installation.
The steps that make a watch repair safer at home are especially important here because the battery and display are tightly packed. Viimon is better equipped than ASDAWN for someone who wants printed guidance and adhesive already prepared. ASDAWN remains the clearer pick for a buyer who prioritizes a stated 296mAh capacity and compatibility with both Series 5 and SE 44mm.
Skip this kit if the watch is 40mm or if the display itself is damaged. For a dead battery in the exact 44mm models listed, the included tools and manual make Viimon the more approachable DIY package.
4. LW Series 3 38mm Screen Service: Best Mail-in Repair
Pros
- Uses an original OEM pull screen
- Mail-in option avoids delicate DIY work
- Prepaid shipping label included
- Repair is stated to take 2 to 3 business days after receipt
- 30-day coverage for certain screen damage
Cons
- You must send in the watch
- Limited to Series 3 38mm models
- Turnaround includes shipping time, not just repair time
Best for: Series 3 38mm owners who do not want to replace a screen themselves.
This is not a loose replacement screen in a box. LW sends an empty box and prepaid shipping label, then repairs the customer's Apple Watch after it is mailed in. That makes it fundamentally different from every battery and screen assembly in this roundup. The service is designed for an Apple Watch Series 3 38mm with a damaged display.
The replacement is described as an original OEM pull screen with LCD, touch digitizer, and display assembly. The listing covers model numbers A1858, A1860, A1889, and A1890. A complete assembly is important when the display is dead or touch is failing, since replacing only the outer glass would not solve those problems.
LW says the repair is completed 2 to 3 business days after the device arrives and then returned with tracking. It also says the team does not factory-reset the watch or access user data. Those details make this a more controlled route than attempting to separate a tiny display at home, but the total wait will include packing, transit, and return shipping.
The screen damage that calls for a complete assembly is the key distinction here. The SJJNHHM Series 7 45mm Screen is a direct part for a newer watch and includes tools, while LW is the better answer for an owner who values professional handling over DIY access. The 30-day coverage applies to non-artificial and non-water damage on repaired screens, according to the listing.
The obvious weakness is the narrow Series 3 38mm fit and the inconvenience of mailing away the watch. Skip it if you have a newer model or need the watch immediately. For the exact Series 3 size, this is the least hazardous path in the group.
5. Soseieiu Series 6 44mm Battery: Best Series 6 Battery
Pros
- 303.8mAh capacity
- 3.85V specification is provided
- Designed for Series 6 44mm model A2327
- Overcharge, overheat, and over-discharge protection
- Tool kit included
Cons
- Does not fit Series 6 40mm
- Not compatible with other Apple Watch generations
Best for: a Series 6 44mm owner who needs a replacement for model A2327.
The Soseieiu Series 6 battery is a precise replacement rather than a cross-generation part. It is made for the 44mm Series 6 A2327 and has a stated 303.8mAh capacity, 3.85V voltage, and 1.17Wh rating. Those details make it easier to verify than a listing that only says “replacement battery.”
The capacity is slightly higher than the 296mAh figure listed for the ASDAWN Series 5 44mm battery, but that does not automatically mean longer runtime. The watch generation, battery health, software, and charging behavior all affect endurance. The useful takeaway is that Soseieiu provides the electrical details needed to confirm that the part belongs to the correct watch.
The cell is described as the same size as the original and designed to fit into the motherboard frame. It also carries CE, UL, and RoHS certification claims and includes protection against overcharging, overheating, and over-discharging. A tool kit is included, but the listing does not specify a printed installation manual, so the buyer should be comfortable following a reliable repair guide.
Compared with the ASDAWN A2181, this is the correct route for a Series 6 44mm, not a substitute for a Series 5 or SE. The differences between watch sizes and generations are easy to overlook because the cases look similar, and this listing specifically warns against using the battery in Series 6 40mm or other generations.
The narrow fit is its real weakness. Confirm the A2327 model before ordering, and skip this part if the screen or force touch components are also damaged. For a healthy Series 6 44mm watch with a tired battery, the clear electrical specifications make this the strongest generation-specific option.
6. SJJNHHM Series 7 45mm Screen: Best Complete Screen
Pros
- Complete LCD, touch screen, and digitizer assembly
- Made for Apple Watch Series 7 45mm
- Repair tools included
- Screens are tested before shipment
Cons
- No repair video is included
- Compatibility is limited to one size and generation
- Installation remains delicate
Best for: Series 7 45mm owners with a dead, discolored, or unresponsive display.
A complete screen assembly is the right kind of replacement when the problem involves more than cracked glass. SJJNHHM's part combines the LCD display, touch screen, and digitizer for Apple Watch Series 7 45mm. The listing specifically addresses failed touch, abnormal image color, and an unresponsive screen.
That makes it a different repair from the UYGHHK 44mm Glass Lens. UYGHHK is for a watch whose LCD and touch functions still work, while this SJJNHHM assembly is intended to replace the active display components too. Confusing those two repair types is one of the easiest ways to order the wrong part.
The listing says each screen undergoes technical testing before shipment and includes a set of repair tools. It does not provide a repair video, instead directing users to online installation tutorials. No panel technology, resolution, brightness, or color specification is supplied, so there is no basis for promising that the replacement will match the original display in every visual detail.
The 45mm fit must be confirmed before installation. The case size is not interchangeable with the 41mm Series 7 version, and the product is not presented as a universal Apple Watch screen. Inspect the replacement before fitting it and contact the seller if there is an issue, since the listing says not to install a problematic part.
The main weakness is the amount of skill the repair still demands. Choose this over a glass-only kit when touch or image quality has failed. If the damage is only a surface crack and the display remains perfect, this is more part than you need.
7. Viimon Series 4 40mm Battery: Best Series 4 Kit
Pros
- Made specifically for Series 4 40mm
- Installation manual and tools included
- Pre-installed adhesive strip
- Force touch sensor flex cable included
- 12-month warranty stated by the manufacturer
Cons
- Does not fit the 44mm version
- No capacity figure is supplied
- DIY battery work can damage the display or sensor
Best for: Series 4 40mm owners who want a prepared battery repair kit.
Viimon's Series 4 40mm kit is aimed at the repairer who wants the supporting pieces as much as the battery itself. It includes a detailed installation manual, a full repair toolkit, and a pre-installed battery adhesive strip. The fit is limited to Apple Watch Series 4 40mm.
The most interesting inclusion is the force touch sensor flex cable. That cable is easy to damage during a difficult opening procedure, so having a replacement available can prevent a stalled repair. It does not make the job simple, but it acknowledges the part of the watch most likely to complicate the process.
Viimon describes the battery as OEM quality and says it has a built-in microchip with protection against overcharging and overheating. The listing does not state capacity, voltage, or watt-hours. That omission makes the product harder to compare with the Soseieiu Series 4 44mm Battery, which supplies 291.8mAh and 3.81V figures.
The difference between this kit and the ASDAWN A2277 is generation as well as size. ASDAWN targets Series 5 and SE 40mm watches and publishes a 245mAh capacity. Viimon is the correct choice only for Series 4 40mm, but its included force touch cable and manual give it a stronger repair-oriented package.
Skip it if your watch is 44mm or if the display is already damaged. For the exact Series 4 40mm model, this kit is a thoughtful option for an experienced DIY owner who wants the key adhesive and sensor backup included.
8. UYGHHK 44mm Glass Lens: Best Glass-Only Repair
Pros
- Covers several 44mm Apple Watch generations
- Designed for cracked front glass
- Repair components and tools included
- LCD and touch layer remain in place
Cons
- LCD and touch digitizer are not included
- Requires a working display and touch function
- The repair is especially difficult at home
Best for: experienced repairers with cracked glass but a fully working LCD and touch layer.
UYGHHK is the most specialized part in this roundup. It replaces only the front outer glass lens for 44mm Apple Watch Series 4, 5, 6, and SE models. The LCD and touch digitizer are explicitly excluded, so the original display assembly must remain functional.
That limitation is also the reason to choose it. If the watch still shows a normal image and responds accurately to touch, replacing only the broken outer lens avoids removing working display electronics. If the image has lines, black areas, color problems, or dead touch zones, this kit will not address the underlying failure.
The package includes customized repair components and tools, and the listing says each component is tested before shipment. It also warns that the seller is not responsible for damage caused during installation. That warning matters because glass separation requires more precision than swapping a battery or replacing a complete screen assembly.
The difference between cosmetic glass damage and a failed display should decide the purchase. Compared with the SJJNHHM Series 7 45mm Screen, this part is cheaper in complexity but narrower in purpose. Compared with the LW Series 3 service, it leaves all of the delicate work to the owner.
This is not the right pick for a first repair. Skip it if touch is unreliable or the LCD is damaged. It suits a skilled repairer who has a compatible 44mm watch and wants to preserve a working display assembly.
9. Soseieiu Series 4 44mm Battery: Best Series 4 44mm Battery
Pros
- 291.8mAh capacity
- 3.81V specification is provided
- Fits Series 4 model A2059 and A1976
- Installation manual and tools included
- Protection against overcharging and overheating
Cons
- Not compatible with Series 4 40mm
- Limited to one watch generation
- No replacement screen components are included
Best for: Apple Watch Series 4 44mm owners with a worn battery and working display.
Soseieiu's Series 4 44mm battery is a tightly specified part for Apple Watch models A2059 and A1976. It lists a 291.8mAh capacity and 3.81V voltage, uses a Li-polymer cell, and includes a repair toolkit and installation manual.
Those numbers are useful for identification rather than a promise of longer runtime. A replacement cell with the right capacity and voltage still needs to be installed correctly, and the watch's age can affect charging and endurance. Soseieiu says the battery matches the original size and is designed to fit the motherboard frame.
The listing also describes protection against overcharging, overheating, and over-discharging. Support is stated to respond within 12 hours and resolve issues within 24 hours, with a 30-day money-back policy. Those support details may help after installation, but they do not replace careful model verification before opening the watch.
This kit is more informative than Viimon's Series 4 40mm Battery because it provides capacity and voltage figures. Viimon counters with a pre-installed adhesive strip and a force touch sensor flex cable. Choose Soseieiu when you have the 44mm A2059 or A1976 model and want the electrical specifications clearly stated.
The weakness is the strict fit. It cannot be used in the Series 4 40mm, and it will not solve a damaged screen. For a 44mm Series 4 with normal display and touch, it is a practical generation-specific replacement.
How to choose best apple watch replacement
The right part depends first on the failed component, then on the exact Apple Watch generation and case size.
Failure type
A battery replacement is appropriate when the watch charges but loses power quickly. A complete screen assembly is for display, image, or touch failures. A front glass lens only works when the LCD and touch digitizer still function normally.
Do not use a glass-only kit to fix dead pixels or unresponsive touch. Likewise, replacing a battery will not correct a display that has been damaged during a fall.
Model and case size
Apple Watch generations often have both 40mm and 44mm or 41mm and 45mm versions. Those parts are not interchangeable simply because they look similar. Check the model number on the watch and compare it with the compatibility list before ordering.
The narrowest listings are often the safest when the model match is exact. A broad compatibility claim is useful only when it clearly names the supported generations and case sizes.
Battery specifications
Capacity, voltage, and battery chemistry help confirm that a replacement belongs to the intended watch. The ASDAWN 44mm Series 5 battery lists 296mAh, the Soseieiu Series 6 44mm battery lists 303.8mAh at 3.85V, and the Soseieiu Series 4 44mm battery lists 291.8mAh at 3.81V.
A larger capacity number does not guarantee longer runtime. Look for the correct model first, then consider protection features, included adhesive, and the installation materials.
A battery can be the right size and still be the wrong part. Match the model number before you open the case.
Tools and instructions
A manual, suitable tools, adhesive, and replacement sensor parts can matter as much as the battery. Viimon's kits stand out because they include manuals, pre-installed adhesive, and, for the Series 4 40mm kit, a force touch sensor flex cable.
Tool kits are not a substitute for repair experience. If opening the display risks damaging a working watch, the LW mail-in service is the only option here that moves the delicate screen work away from the owner.
DIY or mail-in service
DIY parts keep the repair in your hands but expose the watch to damage during opening and reassembly. A mail-in service takes longer and requires shipping the watch, yet it avoids the most difficult screen separation work.
Choose a complete replacement assembly when the active display is faulty. Choose a professional service when preserving the watch and its data matters more than doing the repair yourself.
Frequently asked questions
Can I use a 44mm battery in a 40mm Apple Watch?
No. The 40mm and 44mm batteries are different parts, even within the same generation. Verify the case size and model number before ordering.
Which replacement is right for a cracked Apple Watch screen?
If the LCD image and touch response are both normal, the UYGHHK 44mm Glass Lens is designed for outer glass replacement. If the display is blank, discolored, or unresponsive to touch, use a complete screen assembly or a repair service instead.
Do these batteries fit every Apple Watch generation?
No. Each battery has a defined compatibility range. The ASDAWN A2181 is for Series 5 and SE 44mm, while the Soseieiu Series 6 battery is only for Series 6 44mm model A2327.
Is a repair tool kit included with the batteries?
The battery listings in this roundup include repair tools, but the supporting materials differ. Viimon includes an installation manual and pre-installed adhesive, while its Series 4 40mm kit also includes a force touch sensor flex cable.
What does the LW screen product actually provide?
LW provides a mail-in repair service rather than a screen for the owner to install. The package includes an empty box and prepaid shipping label, and the service is for Apple Watch Series 3 38mm models.
Can I replace an Apple Watch battery without replacing the screen?
Yes, if the screen and touch layer are still working and the battery is the only failed component. Battery replacement still requires careful opening and resealing of the watch.
The bottom line
The Best apple watch replacement here is the ASDAWN A2181 44mm Battery for a Series 5 or SE 44mm with a working display. It has a clearly stated 296mAh capacity, protective circuitry, and the broadest useful compatibility among the leading battery options.
For a newer watch with display damage, the SJJNHHM Series 7 45mm Screen is the appropriate complete assembly, while LW Series 3 38mm Screen Service is the safer route for owners who do not want to perform a delicate screen repair. The UYGHHK lens is reserved for skilled DIY repairers whose LCD and touch layer still work.
If you are undecided, identify the exact model number and determine whether the failed part is the battery, complete display, or outer glass before ordering.
