: More Battery Issues

Damn these batteries! I walked out the door to leave for work this morning at 430 in the pouring rain. Hit the unlock button on the remote as I'm walking up to the beast..no noise from the door locks and no approach lighting..NOOOOO! I hit the remote about 6 more times, to no avail. Major extinction burst lol. I unlock it with the key and hit the ignition (as if it was going to do any good). Had it towed in, dealer is going to charge it in the morning and I'm taking it back for the weekend. Service is scheduled for Monday. I can hear it already: we can't find anything wrong.

This is the 2nd time the battery has kicked the bucket overnight on me. According to Carfax it happened to the other owner also. Once the dealer gets done stumbling around in the dark with it I'll probably end up buying a replacement battery. I've got an iSimple Gateway and 2 10" subs. I'll carry around a booster pack before I remove my audio equipment. Anyone else out there with dead battery problems...you're not alone.

Are your seat heaters\coolers working properly. I say this because in certain trucks these modules go bad and are sucking the power with the truck off. Have them check the modules under the pass seat. If you want to try unplug the harness and see what happens. I am on my second module.

Possible your amp is constantly on? When your vehicle is off the amp should not have power. I would check your accessories first to see if they are draining your battery otherwise you may end up with another dead battery after they replace it.

Heated/cooled seats seem to be working fine. Will keep it in mind. What happened that made you know the module was bad?

Amp is off when the truck is off. Locking/unlocking and opening/closing the doors causes the amp to turn on for about 30 seconds but then it shuts off for good. If I'm in the truck and open the door to turn off the radio, the amp shuts off like it should. Now once it's off if I lock it or open the door, it sends a signal to the amp for about 30 seconds. However it's not in my wiring because before I hooked everything up I checked the Bose amp to sub connection and it does that same thing with no aftermarket amp hooked up. I checked my 11 Silverado, same thing. Basically, locking and opening the door sends a signal through the stereo system. I don't know why.

Anyway..the dealer just called. The battery tested bad and they're replacing it after lunch.

Delco batteries are junk, as many have reported. Most have cured all that ails them with a different brand of battery and or adding a second battery. There's a write up in the FAQs/Tech info sticky at the top of our section.

Take the time for a Big 3 upgrade when doing your battery if you are drawing hard on a sound system. Really helps on the neg side of the current.

I'm definitely going to get an upgraded battery. This dead overnight problem is all too common with Delco batteries from what I've read on here so far. I'm not sure if I want to tackle adding a 2nd battery.

What's a big 3 upgrade?

Updating the ground. Google it, many write ups and tutorials!!

Best to do a battery draw test. That will rule out anything that is creating a draw(draining your battery). 2nd battery is always a good option too.

I had a battery drain issue, even with a dual yellow Optima setup. I narrowed the issue down to the that stupid Lock-Pick contraption. Once I removed that POS, problem solved.

Happened with me 3 times. The first time was right after I picked up the car from the dealer lot. Went home that night, try to program the garage and the phone, listen to the radio, less than 30 all together. Next day, the car wouldn't start.

Even with warranty replacement (and Cadillac send road-home assistant services to my house every time, very prompt & professional services), on the third time, I was tired of it. On the third time, I bought the Optima battery and the guy put it on for me, some adaptor needed.

Haven't have battery problem for the last 2 years. Before that, every six months.

It happened again. There's no question now I'm going with 2 batteries. I'm sick of it. This battery is about 3 weeks old.

How exactly does having 2 batteries help us? Does it just extend the time before the batteries run completely dead? Or if the 2nd battery is only connected to the starter, and not the rest of the electrical system, does that keep it isolated from anything that could drain it?

----------

I'm checking gmpartsdirect.com for the cables. I see positive and negative cables for both main and aux batteries. I'm figuring I need 1 of each for the aux battery?

If a brand new battery is draining in 3 weeks either your alternator isnt charging it or you have a short in the system or some sort of draw....

It's at the dealer again. We'll see what they say this time. Hopefully this gets sorted out right quick.

Got it back. Battery and alternator good. Checked parasitic drain, 22-31ma, within spec. Programmed BCM and rear heated seat module. Disconnected all aftermarket accessories (isimple gateway, Vizualogic a1150 headrest DVD players, power inverter. All installed before I purchased it). Also: repaired radio wires that were cut during installation of accessories. Wonder what that was about. I assume it was done during the Gateway install, only thing behind the radio as far as I can tell.

Something else interesting-- according to Carfax. 1st owner had it approx 3 years, 22k miles. No record of battery issues. 2nd owner had it a year, 7k miles. 2 batteries replaced, negative cable replaced. Makes you wonder.. 2nd owner installs all this aftermarket stuff and problems start? I hope so- easy fix. Time will tell now.

But...if it was something aftermarket, why did my last battery test bad (bad cell)? Coincidence? Maybe repeated deep discharge caused it? Anyone have any thoughts on all of this?

Usually battery issues occur after aftermarket electrical accessories are installed. Sometimes because they are wired up to a constant 12v source instead of the key-on 12v source, and sometimes for other reasons such as the aftermarket accessory having a constant pull when the vehicle is turned off. I would definitely check those with a voltmeter to confirm the issue.

I would but I don't have or know how to use a volt meter. I opened my glove box today to see some sort of brain box with a bunch of wires. What planet is this from? It's a NavTV GMVIM. Video and destination entry unlock. I didn't even know it was back there. From looking at the instructions this contraption is what required wires to be cut during installation. I would have tried it out but I'm not going to mess with it now. This thing has all kinds of aftermarket electronics installed (although disconnected now).
