Petey, Petey, Petey... 
Overall, I was happy with the old battery'* life, it lasted 8 years, pretty damn long in my book. Wal Mart is selling some damn good batteries.

I had a wal-mart battery in my T Type that died after less than a year... so far the replacement battery has held up fine.
From what I've seen on various forums is that wal-mart batteries seem to be a hit or miss situation. Some will last several years and work as they should. Others will crap out after a couple months of normal use. Overall, I'd rather not use a wal-mart battery but in a pinch they work allright.

I'll explain why this is.... Some of the batteries sit way too long... Thats a bad thing.. The battery I bought for my 91 LE in 02/08 was manufactured in 02/08...lol... Thats a very good thing... In a way you could say the battery has a shelf life... All of the batteries I have bought did not sit for any length of time...
If the store has too many batteries and is storing them, you will see more and more of them fail.. Some stores are better than others.. At my store we haven't had a lot of issues in the battery area... And the EverStart is the one to buy..

Shelf life, eh? Any thoughts on approximately how long a battery can sit unused before it starts to have issues? A month? A year?
I know under normal useage a battery is supposed to last 3-4 years for a low-end model...

Same thing goes with a battery in the car.... Let the car sit and never check or charge the battery and the next time you go to charge it or start the car you have found a Bad Cell..
The Longer they sit the worse off they are IMHO

Well, I wasn't on for a whole day (or more), and this thread exploded. I am fairly impressed by all this battery knowledge. It seems that my experiences are outliers. So, are EverStart batteries good?

Something else most people don't realize:
Our PCMs are equiped with a table that dictates what the injector pulsewidth will be given a certain voltage.
As you can see, the higher the available voltage, the quicker the PW becomes. Yet another reason why these cars run so good with higer voltage
As with ANY battery, it is hit or miss. You have to remember...most new batteries now...weren't made of virgin materials. And even location (i.e. climate) dictates how they are to be made. Don explained it to me that southern batteries are made with thicker lead plates to better cope with the heat.
