Hey guys- I looked around the forum but couldn't really find anything to help me out (unless i'm blind). Anyway, here it goes:

I have a '99 GS300 and i use it during the work week. On the weekends I use the weekend car and come monday, after a couple days of non-use, the battery on my GS seems to have drained. It has a hard time starting, the lights are dim, and sometimes the steering wheel adjustor works halfway until the car starts, and then finishes adjusting. I've had my battery for about 3 years now but i remember a time when I left my door ajar and the overhead light was on for about a good two hours. Does that mess up the battery?

What should I do? Should I get a new battery? I spoke to my dad and he said it might be the charging station in the car.

Any suggestions?

Check the battery connections. Otherwise it could be the battery itself. Should last a good five years buth you might have got a bad one. Might still be under warranty.

Ive had that problem before. I thought it was the sound system draining it but honestly all i needed was a new battery. Go to autozone and have them test your battery for you, theyll let you know if its still good or if u need a new 1

It could also be you alternator check that as well.

Once you drain a battery once or more it has been damaged. I would just buy a new battery.

Find out how much amp is it drawing first and report back. You can google this it will show u how. Type battery drain test

I had the same problem before, took the battery to autozone and it tested fine.
Come to find out it was the alternator, when it finally took a crap.

had the same issue a while ago, start with the simple stuff first, check battery terminals and make sure they're tight (mine weren't ) have the battery tested if that fails, worst comes to worst you'd have to check for a parasitic drain in the car. good luck, hope you find the root of the issue.

Well when I got an oil change about a couple of months ago, the dealer said the battery was still 'okay'. It had 35% charge on it still (whatever that means).

Does that help?

I'd check that the terminals are tight and no corrosion, then maybe run it down to a local shop or where you bought the battery from originally and have them test it again. My last car I drove just like you - during the week and then sat for the weekend. By Monday it was a tiny bit slow to start. The battery was 5.5 years old so it didn't bother me.

Then again, if you just have a costco battery, return it and buy a new one

have u recently put a new radio in perhaps?

big1236

No I don't have a new radio. Everything is stock. and I went back to Pepboys to see if it was still under warranty- it's not. the one i bought was a 3 year warranty on the battery and that ended about a couple of months ago....

I'll try to get a new battery, and if that still doesn't fix the problem, i'll have to get the car checked....
