The ANSMANN charger ACS110 is designed for 1-10 cell NiMH/NiCd battery packs with a voltage of 1.2V-12.0V. The device detects automatically the amount of the cells and adjusts the charging voltage automatically. A pre-discharge of the battery pack is optional, then it switches automatically to charging (charging current: 800mA / discharge current: 150mA - 200mA). Once the battery pack is fully charged, the charging current indicator lights green permanently. The charging process is cut-off automatically (-deltaV) and switches to trickle charging. With clear LED indication you can see if the battery pack is charging (LED flashes green) or discharging (LED lights yellow) or if there is an error (LED flashes red).
