Abstract
Some embodiments provide a system that determines a battery chemistry for a battery in a peripheral device. During operation, the system determines a first voltage of the battery at a first time and a second voltage of the battery at a second time. The first voltage and the second voltage are then compared to one or more predetermined battery usage profiles to determine the battery chemistry.
