Abstract
The technology described in this document can be embodied in a method of using a silver-zinc rechargeable battery to power a device. The method includes drawing, in a first mode of operation of a power management circuit, a first current from the battery to power the device. The first current is selected such that a target percentage of a capacity of the battery is discharged in a predetermined time of use of the device. The method also includes switching to a second mode of operation after the target percentage of the capacity of the battery is discharged. In the second mode of operation, a second current is drawn from the battery, wherein the second current is less than the first current. The method further includes powering the device using the second current.
