With this, when you pull the negative cable, it won't reset the computer? :o
So, with the fused model, you still are allowing some drain occurring plus you have the normal battery discharge from sitting. The bypass model seems somewhat defeating the purpose, unless you get the bypass model more as a security device (to prevent starting) vs. eliminating key-off drains.

Well, my H3's goin' to the dealer tomorrow for the dreaded dead battery issue. It's kind of convenient actually, I'll have 'em drop me off at the airport!

Add another to the dead battery list.

I noticed a slow start yesterday afternoon (in Philly) and I couldn't get my XM to work or OnStar. I saw no warning messages or lights. As soon as I got home and parked. The radio & OnStar started working again.

This morning (at home) ...NOTHING...except click, click, click.

No OnStar connection. The clock reset to midnight.

Called OnStar from the house phone and they're coming to pick it up in about 20 minutes.

I replaced the batteries in both of my Hummers with Optimas and have never had a problem. For 140 dollars it gives you great peace of mind and the casing and plates take offroad jolts a lot better than anything out there.

what # battery did you use and did you remove the top cover .
I would like to get a Optima but I mounted a underhood light to the cover and would like to keep it there ?
