hi all, this might sound like a silly question however i am only new to electronics and i am unsure. i need a circuit that charges a 12V 7.2AH battery that is to be installed as a secondary battery a vehicle. this battery needs to power a electronic device once the ignition is turned off without draining the starting battery of the vehicle. any help would be greatly appreciated.
