Hey guys. Long story short my g/f hits a pothole and blows the tire last Saturday . I finally decide to go drive my car thursday night so I go to the garage and notice the battery is dead. The Interior lights were left on judging by the switch. (not exactly the first time she's done this.) Anway after getting a jump the car turns on and I let it run a while before sucessfully restarting it. Today this evening I go to check on the car and thankfully my remote/alarms work but not enough to start the car. So now I need to buy a new battery I guess as this one is no longer holding a charge. What a way to start the holiday weekend. Any suggestions?? I posted here specificaly because I wanted to make sure the battery I buy fits properly and more importantly is strong enough for our cars power roof and all. Please help guys thanx and have a wonderful and safe weekend on the road.

When you say "let it run for a while" how long do you mean? Also, and more importantly, did you DRIVE the car? You need to DRIVE it after jump starting a battery to get the alternator to properly convert the kinetic energy from the rotation of the crankshaft into electrical energy so that the battery can charge via the auxiliary drive belt aka serpentine belt. Simply allowing the car to idle won't really help with the charge in the battery, only temporarily enough to turn it off and on again relatively quickly as you did when you "successfully restarted" it.

If the headlights or in dash lights brighten when you rev the engine, these are signs of a weak battery. This indicates the battery may not be holding enough current to run the car and is working off the alternator (as it was while your car was simply idling in the driveway).

TRy jumping it again and drive that sucker around for 20 minutes.

If not, its possible you need a new battery. How old is your current battery? I would recommend Optima Yellow Top as a new battery if need be. Die Hard batteries are also generally good batteries.

Sorry about the bad timing.

I am one of those that tests my battery and charging system at every oil change just to be on top of things. A nice load tester can be had for under $30.00 from most stores.

Here is a link to my battery install. I have Optimas in all of my cars/trucks.

But as stated ,once a battery is deleted ,a nice charge is required as a short term charge will only give a battery a surface charge which will normally not endure storage.

Optimas for our cars are available from Sears.

Thanx so much guys no I didn't drive the car which was a dumb move by me . I just didn't want to get stuck either. I had a Range Rover and am kinda scarred if you understand me. But yeah I will try the jump again and Ill drive around to bad its night now and must use the headlights but anway thanx. By the way how much roughly for a optima or even die hard. Its been a while since I was in the Battery market. Again thanx again guys fro the quick replies.

make sure the connections doesnt have corrosion on them. I had a problem with my car not starting and it was because of that.

I think you need to take it on the highway or as you guys south of the border call it the freeway

LexLaw

So far so good guys, thanx. I drove around for about 1 hr in the pouring rain. But oh well It just feels good to drive my car again after a 1 week layoff. I'll see how it is in the morning. Thanx Everyone

on battery, i acrtually recommend lexus oem ones (actually they are rebadged interstate) if you don't really do a lot of special stuff with your car. optima are supposedly better if you run audio or so without teh car running, but they have shorter warranty and also more expensive. i thought about getting it for my gs400 but decided i'd rather get the interstate for much cheaper and just as good when i run my car most of the time (when using any electronics)

LexLaw

Thanx again and yes the car/battery is running lovely. By the way How long can u run these cars w/o the engine running with our stock Mark Levinsons? I hate sitting idle but I'm always paranoid.

good question, i don't really have idea. i wonder if it has to do with how loud you put it?

and i am sure with climate control on it's not helping much too

I know I've worked on the car about half the night with the radio on and havent had a problem.

LexLaw

Cool yeah I generally would just have the radio on. No climate control. And yeah I guess volume level would definitely be a factor. I was just wondering if I could go an hour, by that I mean the car battery.
