I found that a 12v 75amphour battery I have is at 50% charge. I was thinking I could go out and get a trickle charger and spend some money to get the battery up again.
But then I got to thinking that maybe I could do it for free if I used the leaf to recharge it.
Would the car's voltage regulator be enough to prevent an overcharge if I paralleled the 12v 75AH to the Leaf's accessory battery?
Or would I still need a separate charge controller in-between? Or because the batteries are different capacities that it won't work?
Thanks in advance.
