I have been told that as well as different strengths of battery (Cold Cranking Amps CCA), there are different types of car battery. And that using the wrong one can cause it to over-charge and the battery to explode.
I am not certain on the names, I think one is Calcium, and the other is Lead Acid, but not sure. I thought they were all lead acid, til now.
To work out which type my car needs, what key words should I look for in the manual?
To work out what type a battery is, what should I be looking for on its stickers?
