Charging Problem?

[Want2GoFaster]

Background:
The battery is a Sears Maintenance Free Die Hard and probably is only about 2 years old. Every year I park the Stang for the winters and put the trickle charger on it the day before I'm taking her out of hibernation. I haven't disconnected the battery over the winter months.
She's been fine until this year.

For the first time, this year I have an issue with starting the car right after shutting it off - it won't. It's as if the battery is drained. If I wait a half hour or so, it'll start but, again, as if the battery was low. If I wait longer - no problems firing her up. She fires up fine the next morning after parking it for the night.
I put it on my trickle charger the other day and when I checked in the morning it showed that the battery was fully charged. But today, same problems.

Any thoughts?

Thanks

Is the battery still covered under warranty? It does sound like the battery.

I think so. I have the paperwork in my glovebox. But the Stang's at the shop getting my X-pipe installed. I pick it up tomorrow. I'll stop by Sears and have them test it.

Thanks

I had a truck that ATE batteries. I started buying the walmart batteries and exchanging it every year before i had problems....

before you do it try this:

Take a DMM and test the voltage output and see what it's putting out. Take a piece of wire and connect it from the frame to the alternator housing. If the voltage jumps up then your problem is a bad ground.

If you don't have a DMM then you should be able to hear the change in engine idle once it starts charging right.

I'd recommend buying one as you can get one for roughly 15 bux

Thanks for the help. The battery was done.
