I took our golf cart battery with the broken terminal to a
Club Car repair person thinking I might be able to exchange it for a
used battery.
The guy told me he was fresh
out of used batteries and didn't recommend putting a new battery into a
bank of older batteries for a few technical reasons.
You can get a self tapping
repair terminal at most auto parts stores for around 3 dollars. Be
careful not to drill the pilot hole too deep.
