Charger use and maintenance: 1. When charging, connect the charger to the battery first, then plug into the AC power. After charging is complete, disconnect from AC power first, then unplug the battery. Disconnecting the battery plug first during charging, especially when the red light is on, may damage the charger. 2. When the LED turns green, continue charging for an additional 2-3 hours. 3. Do not fully discharge the battery before charging. Charging after complete discharge may result in reduced battery performance or damage. 4.
