Gather a new CR2016 battery, which is widely available at most general-purpose stores. CR2016 batteries are widely available at most general-purpose stores. If your KardiaMobile is attached to a phone clip, firmly slide it out of the open end of the clip using both thumbs before proceeding.
Locate and open the battery compartment
Turn the device over and locate the round battery cover on the back. To open the battery cover, insert a pen or a similarly shaped object into the notch on the round cover and gently pop it off.
Remove the old CR2016 battery
Take out the depleted battery from the compartment. Note its orientation so you can insert the replacement correctly.
Insert the new battery correctly
- When installing the new CR2016 battery, ensure any protective sticker is removed (if applicable).
- Insert the new battery with the plus sign (+) facing up, sliding it under the two metal tabs inside the compartment.
Close the cover and test your device
- To replace the battery cover, align the single tab on the cover with the slot on the left side and insert it first.
- Press down on the right corner of the cover until you hear a click, indicating it is securely closed.
- After replacing the battery, it is recommended to restart your device.

Troubleshooting and special cases
A new battery is expected to last 1-2 years with normal use (2-3 readings per day) or approximately 200 hours of operational time. If the battery needs replacement in a matter of days, weeks, or months, it is less likely to be a battery issue, and you should contact support. Note that the KardiaMobile 6L model has a different battery replacement process, requiring a Phillips P00 screwdriver to access the battery under the bottom electrode. If you are experienced with replacing watch and device batteries, you may find similar skills apply here, though the KardiaMobile 6L is a separate case. For other household devices, you might look up how to change battery in Nest thermostat or change Liftmaster remote battery, but for the standard KardiaMobile, no screwdriver is needed. Managing your device's power is also straightforward, similar to checking Fitbit battery and power settings, you simply monitor usage. When the old battery is removed, remember to dispose of a lithium battery properly at a designated collection point, just as you would take out CMOS battery from a computer. The KardiaMobile battery is not rechargeable, so always use a fresh CR2016.
