Thanks. It's only 3 years old but a few times I haven't been able to start the car. I should have figured it was the battery but it's no that old.
These little batteries typically lasts around 4 to 5 years. But once it has been drained, the life span will be reduced. It's time to change the battery before you get stranded.
Well then it could be a bad connection at any of the 4 connection points for the 2 main battery cables. Problems at the body-frame connection for the negative cable seem to be fairly common. Anyhow, all 4 connection points need to be removed, cleaned and re-attached and the battery needs to be tested. While a "good" battery test sometimes isn't conclusive, a "bad" test almost always IS.
