- Tips: If your battery is 12V, and the charger, when the charger detects that the battery voltage is lower than 7.5V, the charger will assume that the battery is 6V, which means that the battery is over-discharged and needs to be charged in forced charging mode. Force charging mode: Press and hold the button for 6 seconds. After the buzzer sounds, connect the battery and press and hold the button for another 6 seconds.
