A:  Hello George! Great question. The charger will periodically wake from standby mode to ensure the battery pack remains in a fully charged state until ready to use for that project. We do not recommend leaving the battery and charger plugged in at all times. Disconnect charger from the power supply when not in use. This will reduce the risk of electric shock or damage to the charger if metal items should fall into the opening. It also will help prevent damage to the charger during a power surge.
