Fitbit has been a trusted companion for many fitness freaks for a long time. But what if you suddenly find your Fitbit dead, and even after charging it for hours, your Fitbit doesn’t work? You might think of replacing the battery, but can a Fitbit battery be replaced? Or do you need to buy a new Fitbit? Let’s dig deeper and find answers to all your questions!

A number of Fitbits are available in the market that can easily be charged when their batteries are draining. But do you know how long Fitbit batteries last? It usually lasts around 3-6 years, depending on your usage and charging habits.
So, if you have an older Fitbit and are looking for a battery replacement, then here’s the truth: you cannot replace the battery of most Fitbits. However, a few older models of the Fitbits do allow battery replacement through unofficial methods.
If your Fitbit battery can be replaced, then you can do so by opening the back, removing the old battery, and putting in a new battery. However, if you don’t want to void your Fitbit warranty, then don’t replace batteries in spite of the low Fitbit battery replacement cost.
What you need to know about replacing your Fitbit’s Battery
If you want your Fitbit battery to be replaced, then it is only possible in some older Fitbit models.
Fitbits have a lithium-ion battery that is rechargeable from time to time. There are a number of Fitbit smartwatches that can be charged whenever their battery is draining. Moreover, on a single charge, these Fitbits can work for two to seven days, depending on the model of Fitbit you are using, your usage of the device, and your charging habits. If your Fitbit is not holding a charge or is dead and you are unable to charge it, then you need to replace your Fitbit battery.
1. No Guaranteed Performance Even If the Fitbit Battery Is Replaced
If you feel that your Fitbit battery has been damaged or your Fitbit isn’t working because the battery needs to be replaced, then remember that there is no guarantee that your Fitbit will start working even after replacing its battery.
2. Replacing Fitbit Batteries Voids The Warranty
If you replace the battery of your Fitbit, then it is going to render the warranty void, even if your product is under the one-year warranty period. This means that if your Fitbit doesn’t work even after replacing its battery, you can’t even avail its warranty, since replacing your battery yourself will render it void.
So, it is better to contact the Fitbit support team in case of any battery malfunctions before replacing it yourself.
3. Fitbit Battery cannot Be Replaced For the Versa series
As we have discussed, several Fitbit batteries cannot be replaced, and the Fitbit Versa series falls into this category. You cannot replace the batteries of the Fitbit Versa, Versa 2, Versa 3, and Versa 4 models because they are sealed and built-in.
So, if its battery dies, then the only option left with you is to buy a new Fitbit or check with their support team if it falls under warranty.
How To Change a Fitbit Battery?
Fitbit advises its users not to attempt to get their Fitbit battery be replaced since it will void their warranty. Nevertheless, if you are ready to change your Fitbit battery, then here is what you need to take care of:
You can change your Fitbit battery yourself if you are confident in your technical capabilities. I would still strongly suggest that only experienced technicians attempt the same.
