How Long Do Fitbit Aria 2 Batteries Last? (2024)

The Fitbit Aria 2 utilizes three 1.5V AA batteries, and while Fitbit says that most Aria 2 owners should get a year out of them, the company acknowledges that this time could vary based on a few factors, such as how often you use the scale. Note that whenever the battery life runs low on the Aria 2, it will provide you with an alert on its display.

Wi-Fi is also an important factor. The Aria 2 can connect to your home Wi-Fi network, and depending on where the scale is placed in your home relative to the closest Wi-Fi signal, the Aria 2 might expend more power maintaining a connection.

When it comes time to replace the batteries in your Fitbit Aria 2, you'll need, as stated above, three AA batteries. While they don't necessarily need to be 1.5V, it's best if they are if not higher, as lower-voltage batteries won't last as long as those with the proper voltage.

With an expected battery life of about a year, you shouldn't need to worry about the battery life of your Fitbit Aria 2. Just make sure to have some AA batteries handy for when the time to change them does arrive.
