Description
Your Apple Watch SE (3rd generation) no longer holds a charge the way it did when it was new? Shutting down unexpectedly, or only working while on the charger? Those are the classic symptoms of a worn battery.
A tired battery can also swell inside the case and damage the surrounding components, so it is worth replacing rather than living with.
This battery is brand new and built for customers who demand the same quality as original batteries.
- Zero cycle count
- Tested under extreme weather
- High output current capacity
- 1 Year Warranty
