Batteries and How to Charge Them

• Sealed lead acid battery charging - But you need to do some research on how Lead Acid batteries work and how to charge them... Most small lead Acid batteries have a specification on the side, and typically Charging current: 0.7A~0.8A (Below 1A) Charging Voltage: 13.5V~13.8V DC.  Many Power supplies and chargers charge at too high of a charging current... which can damage the battery

  • For 12V 7AH Battery Charging current: 0.7A~0.8A (Below 1A) Charging Voltage: 13.5V~13.8V DC
