How old is it?

2-3 years old


That's just beyond the warranty period, like all of wally-marts
batteries do.

First check the voltage coming out of the alternator at a higher than
idle engine rpm.

It should be no more than 14.2 volts. If it is than that is the reason
the battery is failing.

John, it is below that, I have a voltmeter on my dash.

I wouldn't trust an in-dash voltmeter to be that accurate.
