Battery Care

The battery, made of Lithium Ion (LiIon) 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.
