Wait, Even a NEW battery will get warm while charging... While charging a battery, the caps should be taken OFF, if not, this is how the gas builds up inside & very slowly comes out the vent holes & then with the first spark, BOOM!!!..
I should have said TOO warm. When using a 6 amp or less battery charger, the battery should see very little rise in temperature. Whether the caps are on or off, it's never wise to make a spark near the battery while charging.
A long low charge is much better for the battery than a fast high charge.
When I was using the 1 amp charger and felt the battery was pretty hot after a couple hours, I should have removed the charger and tossed the battery away. Instead I let it charge overnight, hoping it would come around. Live and learn!
