How Long Will the CorSense Battery Last?

Like all lithium-ion batteries, there is no indefinite shelf life, but the vast majority of units are fully functional several years into use. The battery is not replaceable. The need to recharge the battery depends on movement and how used. If it is stationary and kept in the original box, only used for short daily readings, battery life should last 3-6 months. 

Currently, there isn't a way to check the battery level for the CorSense in the app. We are working with our design team to get the CorSense battery level added to the app. In the meantime, if you want to charge your CorSense up once a month or even every couple of weeks to be safe, the extra charging will not hurt it.
