I am trying to get a better understanding as to what can cause a car battery to corrode at an accelerated rate.
My friend's truck has developed an electrical issue and we noticed that the terminals on the batteries corroded about 2 days after cleaning them. The batteries are fairly new. The truck has two batteries and we noticed that one battery has the negative terminal corroded and the other has the positive terminal corroded.
Is there a specific reason why they would corrode in such a short amount of time? Is there a difference as to why the negative terminal corrodes versus the positive terminal?
