What kind of battery?

[H2-USA]

I replaced the orignal battery in my 2003, after is was leaking all over the front tire....... after just under 2 years.(forget the delaer)
I replaced it with a yellow top Optima battery. About 6 months ago, after only driving my vehicle every couple of days (short distances), the battery would act as if it were almost dead and not start the vehicle, I would jump it and be fine for the rest of the day, only to have it occur a few days or weeks later, or if it was really cold in the mornings (40s).

I contacted Optima, and they stated that they do not make a battery for any of the 2003 - 2007 Hummer H2s. They said that the stated cold cranking amps required (in the book) for the H2, is 880. The Yellow top Optima only has 750, and the Red top Optima only has 800.

I tested the battery, and it was only carrying 8 volts and dropped to 5 under load. After fully charging the battery it seemed fine ................

Long story short, I called Sears, they don't have a battery for the H2, though he said that could get one to fit .......... max 800 cca.

I went to Walmart and Sam's club, their books list the H2, but no battery options.

Finally I contaced AutoZone. They have a direct replacement 880cca battery for the H2s. 79-DLG (Duralast Gold) $99.99
8 Year/96 month warranty with 36 free replacement period.

DONE - GAME OVER. The H2 event starts faster with this battery, turn the key and rrumpp it's ready to go.

This is my story. Others wil swear by the Optima Batteries, which I did so before. My other vehicles have the Red Top Optimas.

Happy Trails.
