Dead battery and oil life question

[Hal]

I'm getting ready to go in for my second battery replacement and by the way, I don't have any accessories plugged in that could cause a mystery voltage draw, I'm even anal to the point where I always turn off the radio and climate control before turning off the ignition. I know this topic has been visited a lot but has it ever been resolved?
on to my real question...
When the battery dies and gets removed and replaced what happens to the almighty oil life sensor algorithm thingy? Does it just reset and think you had an oil change too? if so, some folks could have some nasty oil and the computer would never know it. I change mine based on mileage (yes I'm one of those dorks). But what do you think about the computer/oil/battery thing? (F5..)

I would asume that the oil life monitor is incorporated in the cars computer which has an internal battery. Otherwise when battery is removed the computer would be wiped out, including mileage.

I had the same issue and it's happened 5 or 6 times. Hummer simply stated I wasn't driving the car enough. There is a problem and they won't acknowledge it. For that reason, I'm eventually going to trade my H3 in on something else. If you hear of anything, I would like to know.

I unhooked the battery for my underhood light install and the oil life reset.Also when the dealer replaced the battery in march 06( I found out when I got the on star report)Current battery is holding up well,to be changed over to a optimum in the future.

The total miles on the car I guess is protected.As was the compass and temp on the mirror and the horn chirping when locking and unlocking.

My aftermarket radio had to be reset with time ,stations ect.

I just had my battery replaced for the first time at 35,000 miles. My driver's window would not operate and the automatic door locks would not function.

I had that happen when the battery went dead.
After it was jumped and running for a while it went back to normal.

Just came back from a trip and after sitting 7 days with no drains the battery was dead. After a short jump it stated up. GM should be ashamed of itself to install inferior batteries in a Hummer. Selling my GM stock...

Thats funny, my buddy drives a Canyon and goes through a battery about every 8 mos and GMC told him he drives too much(80,000) per year and that it was charging the battery too much and creating a memory like nicads do

My 06 H3 doesn't get much use due to my schedule. I bought it in Aug 06 and haven't even broke 3000 miles on it. The battery issue isn't helping. The original AC Delco had to be chucked as soon as I get it to Germany as it wouldn't even take a charge. I couldn't get an AC Delco replacement, so I went with the Optima Red Top. Unfortunately, it won't hold a charge beyond about 10-14 days. If I drive the H3 about once a week, it seems to keep enough juice; unfortunately, I don't have the luxury of driving it once a week.

The H3 is sitting next to a 97 Explorer. It goes weeks and weeks at a time with out running. I was recently away for 6 weeks, and it still started like a champ.

Therefore, I am scratching my head. Can the H3 actually have 2 bad batteries: AC Delco and Optima? Or, is there some sort of parasitic drain (no PIAAs, no new stereo, no alarm ...)?

Consider using a "battery maintainer", plugs easily in the cigarette lighter. Porsche sells them for about $80 (US dollars).
