Battery Care

The battery, made of Lithium Ion (Li-Ion) rechargeable cells, is integral to the device and cannot
be replaced by anyone other Nonin Technical Service. The life expectancy of the battery is
approximately 1 year.
For optimal performance, the battery should be replaced once per year to limit the amount of Li
build up if the battery is charged in a cold environment.

Maintenance
