Dead battery and oil life question
 

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..)

Re: Dead battery and oil life question
 

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.

Re: Dead battery and oil life question
 

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.

Re: Dead battery and oil life question
 

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.

Re: Dead battery and oil life question
 

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.

Re: Dead battery and oil life question
 

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

Re: Dead battery and oil life question
 

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...

Re: Dead battery and oil life question
 

30k miles, go on weeklong trips away every couple months, leave stuff like cell phone charger,ipod, 75w inverter all plugged in while I'm gone. Never even blinked an eye starting. If you are willing to sell your GM stock (or whine about never buying a hummer again because your battery went dead :crying: ) STFU and go home :fdance:

Re: Dead battery and oil life question
 

Has anyone put in an Optima or other battery and had it go dead??? that would be the definitive test to see if the Hummer is sucking the juice or if the batteries just SUCK! I can't believe there could be so many defective batteries but I could easily believe that the Hummer has a defective design.

I should probably just get a Wal-Mart battery and then if it goes dead in 3 to 4 months at least I would only have to drive 1/2 mile instead of making an appointment and driving 60 miles to the dealership AGAIN!

:( :( :mad: :mad:

There are plenty of threads here about batteries. GM Batteries are the most common complaint, well known fact. You can get a bad one one time, then a good one (like me *nyah*). Most 'dead battery' cases are either a bad battery or parasitic drain from an aftermarket product (usually new stereo or ipod adapter incorrectly installed).

Hey I understand you have a bad battery, it happens. That's the risk of having a hummer dealer a long way away. It's also why you have Hummer Roadside assistance - QUIT YER BISHING.:violin: :violin:

Re: Dead battery and oil life question
 

Batteries going bad is NOT a Hummer H3 option; it is a free option on many cars, GM and other manufacturers. The rate of battery failure on the H3 is the same as on any GM vehicle, and from comparing notes in the auto industry, it is the same on any major brand. For all of you who have had one or two batteries, I don't know of anyone personally, who has replaced a battery in the first three years. Factory installed batteries meet manufacturers requirements, but that does not mean they are the greatest batteries made.
I did replace one in the first year of a vehicle's life, but it was my 03 Jeep Wrangler.
Now, if my battery does go dead, I will replace with an optima.

Re: Dead battery and oil life question
 

We are talking about dead batteries replaced 2-3 and 4 times. It's a pain in the ass going to the dealer when they are an hour away. Anyway, try unpluging all that stuff and let your truck sit for a week then drive it one or two days then let it sit for a week. Chances are you'll have a dead battery too.

I'm not complaining about my Isuzu Rodeo 4x4 or Grand Cherokee Overland 4x4 because they never had to go back to the dealer for anything! ever! WTF is wrong with GM? you tell me...

Re: Dead battery and oil life question
 

I have had my truck go dead 7 times. It even went dead in the dealer parking lot after they jumped it last Friday. According to GM, there is a service bulletin for the 07' that changes out the battery. Maybe Fstop5 can confirm? For some reason, it's not for the 06', but the Regional GM Tech rep has recommended my dealer do the replacement. BTW, this will be the third battery and they keep shifting the blame my way. "The car needs to be started daily. Even if you don't drive it, start it and let it run a while". WTF. I mean, seriously, WTF. :lame:

Re: Dead battery and oil life question
 

Agreed that it is lame to have a half assed battery in a premier off road vehicle. GM should spend less on the appearance of a fancy battery casing with a snorkle vent. Spending more on the lead plates that give battery some balls would be better!

Re: Dead battery and oil life question
 

Hi Hal, I continue to have battery issues since the day I bought my 06 H3. Unfortunately, I don't have a nearby dealer to help deal with the issue. I had replace my factory AC Delco with an Optima Red Top. Unfortunately, the H3 can only sit a few days before the Optima is dead. I have Germany's roadside assistance, jumper cables, and a battery booster pack. The latter has a little baby battery in it to allow you to jump start yourself. Despite being a total pain in the @ss, the latter thing has been a life saver. Now, if I could just magically figure out why my H3 hates me.

Re: Dead battery and oil life question
 

I never had a problem with my battery. Im at 13k now. I've had it sitting for 2-3 days with no probems afterwards. I've checked and i have about 50 mA drainage(no alarm) and 67-70 mA drainage when the alarm is on, and i have tons of electronic aftermarket accesories which i installed myself. it is and maybe it isnt the battery.

Also to the origional question, i've disconected my battey many many times, and the oil life never reset itself. the only thing that resets is the switch for teh fog lamps, if you had it to on, it will be off when you reconnect, of and also the radio stations on my aftermarket pioneer.

just my experience.:beerchug:

Re: Dead battery and oil life question
 

there does not seem to be a pattern...

Re: Dead battery and oil life question
 

1. Yellow 06 (Jan) 20000 miles, no battery problem... longest it sat without being started was 10 days

2. Gray 06 (Jan) 5000 miles, no battery problem... longest it sat without being started was 4 days

Re: Dead battery and oil life question
 

oh i forgot about the time when i was out of the country on vacation, the 3 sat in the garage not started for 1 month, when i came back it cranked right up. thats a good battery in my opinion.

if i start having a problem with the battery, or if i ever did, and im sure its the battery, i wouldnt go to dealer, would just buy a nice optima and not have to worry about it for a while.

Re: Dead battery and oil life question
 

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:confused:
