10.8V (85Wh) Lithium Ion Battery. Tested, fully working.
The internal battery management system (BMS) is System Management Bus (SMBus) and Smart Battery system (SBS) compliant and can operate as part of a smart battery system along with a compatible smart charger and a host device. The BMS provides cell and battery level protection against over-voltage, under-voltage, over-current, short-circuit, and over-temperature. The communication interface allows a host device to read pertinent battery data such as Runtime to Empty (minutes), Full Charge Capacity (mAh), and Relative State of Charge (%) which are provided by the impedance tracking fuel gauge. In addition, a wealth of other calculated and static data is available making the battery an active part of any power management system. When connected to a smart charger, the battery broadcasts its required Charging Voltage (mV) and Charging Current (mA) which the charger provides until commanded to stop charging.
