Can the Weza recharge deep cycle 12v RV or marine batteries? And how much foot pumping would it take to charge one approx?
It will charge any 12V battery, but the issue is that the time to charge any battery depends on the capacity of the battery IE larger battery takes longer to charge. If you want to do this then we suggest that you disconnect the “link” on the Weza side panel. As an estimate take the capacity (in Amp hour) of the battery and divide by 3 – Answer in Hour. Weza was never intended to fully charge an external battery. It was more for jump starting a motor.
