This is one brand new 80mAh battery manufactured by Tanin Auto Electronix for use in the Fitbit CHARGE and CHARGE HR. A special Torx tool will be included with your purchase as well. These Fitbits commonly experience battery issues such as draining too fast or not charging.
After installing your new Fitbit battery replacement, you should expect at least 4 days of battery life before needing to recharge. If you do not see these results, then please contact us. Keep in mind that daily usage, all day sync, heart rate monitor set to “on” instead of “auto”, and other factors may decrease the time needed between charging.
If your Fitbit has water damage, endless Fitbit “resetting” & power cycling, or other issues, then a new battery will not help you. Also, please note that if you install the new battery and only get 6-12 hours of life, then there is an underlying issue with the Fitbit that a new battery will not fix.
We do not offer any additional technical support for this DIY part. The replacement battery will come with a free Torx tool needed to disassemble your Fitbit, however, you will also need a precise ability to solder.
Please watch the video shown below to ensure you are able to install the replacement Fitbit battery yourself. If you are not confident in your abilities to install this, please let us take care of it for you with our repair service.
