To replace the battery in your KardiaMobile EKG, remove the monitor from your mobile device and slide if out of its attachment clip.
The battery compartment is located on the back of the monitor. Insert a pen, pencil or other similarly shaped object into the cut out next to the battery door to pop the battery door off.
Replace the dead battery with a new coin cell battery, 3.0V size '2016'. Be sure to use the same battery model type. These batteries can be found at most general-purpose stores.
When installing the battery, make sure that:
- the protective sticker is removed from the battery (if applicable)
- the battery is inserted with the proper polarity (you should be able to read the writing on the battery after placing it into the compartment).
A new battery should last 1-2 years of normal use (2-3 readings a day), if you feel you have to replace the battery in a matter of days, weeks, or months, please contact support as it is less likely to be a battery issue.
