This applies to K800 but it seems also to apply to M510. The numbers are based on the HID++ 2.0 spec that state the following for GetBatteryCapability: If number of levels < 10 or if mileage is disabled then report are mapped to 4 levels this way. 0%->10% critical 11%->30% low 31%->80% good 81%->100% full i.e. to report battery low, FW send 25%, to report battery good, FW send 50%. |
