The Mirka® intelligent Li-ion battery allows a precise capacity
measurement based on a coulomb counter. With Bluetooth and the
myMirka® Dashboard, you can easily monitor battery health status
and available capacity. It is also possible to monitor individual
cell voltage and together with the coulomb counter both battery
lifetime and usage time can be prolonged. The firmware in the battery
is upgradeable via Bluetooth connection of the sander/polisher.
The 10.8V 2.5Ah battery has 3 cells and charging time is
approximately 45 min.
