Description
Replace that dead or dying battery. Does your battery die too quickly? Will your battery not charge? Are you having other issues with your battery? Replacing it may help!
Our aftermarket replacement batteries lead the industry in quality and reliability. Rest assured you're getting the best part money can buy.
- 0-Cycle - Each cell is brand new and has never been used.
- Rigorous Testing - Every single battery cell is tested to ensure it meets our specification.
- No Shady Business - We don’t modify the battery’s capacity or cycle count information to make it look better than it actually is.
- We’ve Got Your Back - 1 Year Guarantee - We spend countless hours making sure we provide the best batteries you can get. We are uncompromising when it comes to safety and performance.
For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.
