From the Stanley 1M Series Spotlight manual:

This unit is shipped in a partially charged state. Charge unit BEFORE first use using the 120 volt AC charger for 24 hours. Recharge after each use.
The charge status LED lights while the unit is charging and stays lit while the charger is plugged into the 12 volt DC charging port.
When the spotlight dims, the unit needs recharging.
