Battery keeps dying!

The battery in my wife's 06 died this past spring; 6 years on her OE battery; and the OE battery in my 07 still starts the car after she sits for 2-4 weeks at a pop. I really think that it's a matter of certain production runs of the battery and/or alternators that is the deciding factor since many, many folks haven't had the problem but such an unusaully higher percentage of owners DO have it. We'll never know for sure.

Optima yellow top.
Simply put, when you deep discharge a normal battery a few times, if kills them. This does not happen on "deep cycle batteries." Any time I found my battery dead, simply gave it a jump start and went for a ride, no replacement needed.
The car was mostly used for short trips, about once per month and sat for 99% of the winter. 11k miles in 3 1/2 years with a 2000w rms stereo system. Pretty much the worst case scenario for a battery.
The next mods if I ever decided were going to be a higher amp alternator and "the big 3." take a trip to google if you don't know what that is.

I have a 2008 mustang convertible GT and 2 yrs ago battery kept dying. Had it replaced twice found out it was a short in the battery terminals. Now, almost 3 years later, battery dying! Thank God it's under warranty but hard to believe its just the battery. Anything else I shod check out? Need advice! Thanks

Hope this works! Anything else I should check? I moved in May so I don't have a regular place to have it checked. Plus I'm a girl w/ a Stang that doesn't want to get ripped off.
Any help appreciated-Thx

I think it has to do with the battery that the factory installs when you buy your car. I don't think they are as good as Diehard, Duralast or any other types of battery that you see in an auto parts store.

It's the PC680. Not quite 11 lbs. You have to buy the automotive terminals and mounting bracket separately. Here's a pic of the battery installed:
*Christ, thats a huge pic. Sorry, don't know how to re-size them with my tablet.

I'm on my 3rd battery. The stocker died at 3 years, the autozone battery leaked and died in less than 3 years, but I'm pretty sure it froze to death. Now I have a battery from oreilly's and it's leaking too!
