#331 of 2056 Battery Died?
Feb 12, 2010 (3:47 pm)
I had my 2010 Buick LaCrosse CXS since Oct 2009 and only have 1373 miles on it. I had it in my garage since Sunday with the Alarm set (blinking red light on Dash.) This morning I went out to start the car and it was battery dead. It has been in the 20s for the past days. I am in the process of charging the battery and after a slow 2 om charge, it started and looks OK. Will let it remain on charge for about a total of 8 hours. I did check for open doors/trunk, but found none.
I assume it is just a freak occurrence. I have had cars sit out in this and lower temp for at least 2 weeks without a problem.
Any suggestions or advise?
I will start it at least every other day from now on. Yes, I do have another car that I use when it snows or we have bad weather that I drive.

if it is not a sealed battery, suggest you check the fluid levels in the cells. also, you may want to consider buying a "battery tender". you hook it up and leave it on the vehicle when you know you are not going to be driving it for a few days. provides a trickle type charge which keeps the battery at peak charge. after the battery reaches peak charge, it automatically stops charging and then kicks on again when below peak.
if you merely start the car every other day without driving it or letting it idle for quite a while, you will be doing more harm than good---because you will put a drain on the battery everytime you start it and then if you turn it off in a short period of time, it will not have had time to re-charge.
But I agree with you, something sounds fishy as to why the battery was dead.

Thanks for your input. I do have it on a 2 AMP charge and charging it for 8 hours. It is a sealed battery. I agree with you, as to starting it and not driving it. I will drive it more, but I still don't understand the battery drain. Will post more on the results for others INFO. Thanks again.
#334 of 2056 Nice Leather

I had the chance to stop by the auto show and sit in the new LaCrosse. It seemed very nice and I really liked the leather they are using. Too often leather on cars is more like upgraded vinyl, so this was a nice surprise.

Take it to the dealer. Although I didn't have this problem, they did do a battery draw down test on it, as there is a TSB or something for it. Good luck.

2 amp charger, 8 hours, that is only 16 amps. Hardly enough to make a difference on a dead battery, unless it is for a lawn mower or motorcyle.
Are you sure it was the battery and not a malfunctioning start circuit? One way to check the condition of the battery when it won't start, is use a charger of 10 amps or more with a meter. Watch how many amps it is drawing when it first starts charging. As the battery is replenished, it will eventually start drawing less current and taper to near 0. If this occurs quickly, then the battery is incapable of holding a full charge. Example, assume a battery of 350 cranking amps. If it was fully dead, at 10 amp charge it should take about 35 hours to charge. It may only need to be half drawn down to not start, say 175 amps, That would still take roughly 17.5 hours at 10 amps to fully charge. Assume you have a battery that won't turn vehicle over. If charger indicates it is charged in an hour or less, it might start vehicle now, but it is also a battery that is on its last legs.

Interesting; there was an article in the ocal paper over the last week or so on this very subject. They talked to a mechanic who said the "vampire" loads on batteries in current cars can kill a battery in a week or so if not driven. They also talked to those running the long-term parking at the airport, who said that they have had to equip themselves with quick-start battery jumping units because of the problem with so many customer cars refusing to start upon return from their trips.

I did a 2 amp charge for 20 hours and got in and it started up the next day. Drove it yesterday and today without any problems. I may have been unclear when I said I tried to start it. The car was completely dead. The remote unlock would not work, I had to use the key to open the driver door. No lights came on, nothing before I charged it. After the charge and the first start, I noticed the Compass had to recalibrate, my clock was off by an hour. Other than that, no other changes noticed. Will continue to report how it is going.
Thanks for your replies and information.
#339 of 2056 CXS won't start
Feb 15, 2010 (7:03 am)
I just took delivery on my CXS on Saturday and had it in the garage for three hours yesterday learning all the systems and downloading CD's into the hard drive. I noticed the battery indicator light on the dash but since it's a new car didn't pay much attention and continued to play with the nav and music features. I went to the gagage last night to take it for my first night time ride to see the interior lighting and it would not start. The HID's came on as did all interior lighting but nothing happened when you press the start button. I put a charger on it for about 30 minutes and it kicked right over. Drove it for about 30 minutes and now back to normal. I guess all of the electronic stuff in the LaCrosse does draw a lot of current when in the accessory position. I'll keep an eye on this during future music downloads.

Both of you having such problems seems really strange. Electronics don't draw much power, not near as much as lighting or starter. And several GM have something built in to shed load so you don't draw down to the point it won't start.
I'd check if you have that, and learn how it works since it might be malfunctioning.
It is also likely that in trying to shave pounds from the vehicle, lead being so heavy, they are using a battery that is at minimums for the vehicle or you got a battery that sat during the whole time GM was shut down.
I had a ford that required a special battery, 1300CCA. Unfortunately there was not a great demand and no aftermarket available. The last time I needed one, they had it on shelf. It had been sitting almost a year but would not take a charge. They ordered from next level up. Took almost a week to get and same thing. They ordered through Detroit and got a fresh one from manufacturer. It lasted 74 months.
I don't know why a battery will die if left sitting on shelf. It does not just drain of power, it will not take or hold a charge.
With the number of battery problems I've been hearing about on new vehicles, 09-10, even on the lot, I'll venture a guess that those batteries were stock piled somewhere for a length of time.
