Default Humidity+Heat=Dead Battery??

Hey guys,

I recently moved to Florida's panhandle and as you can guess...it's hot. And humid.

So I get in my car in about 95 degree heat with about 70% humidity. I go to start it and it turns over a bit slow, and then fires up. I drove a few miles to the gas station, and it promptly would not start after gassing up. It would start to turn over and then click click click etc. After jumping it and driving home (18 miles) it was fine the rest of the day and for about two weeks.

Once again, it started a little slow, I drive a few miles and it won't start again when I shut it off. It's hot again with about the same humidity....what gives?? Any clues? After jump starting it again, no problems to date...

Any help'd be appreciated,

Steve

Hmmm, have you checked the battery water levels lately?

If that's still the original battery in the car, it's certainly lasted longer than many others.

Stock batteries have limited lives. So do dirty batteries. The dirt across the top of a battery will slowly conduct electricity. Add in humidity and salt in the air (if you are that close to the ocean) and that makes it (the conductive film of dirt) worse.

Other things to check would be the alternator. If it doesn't produce over 13v at idle and/or doesn't increase to over 14 when revving the engine, it might be dying.

And then check for a draw. Disconnect a terminal and reconnect thoguh a meter set on amps. Or use a test light the same way. The test bulb, with doors shut, car off, no under hood light plugged in (if applicable) should only light very dimly, if at all. Most cars pull some current for clocks and such. Opening a door should make a very distinct difference in brightenss (it should get a lot brighter)

OE spec for power off currnet drain is 21mA (if anyone wanted to know)

my recomendation is to have the battery tested, you may have sulfated plates. any shop with a VAT can test it for you and it will take like 5 minutes. if its dead then you get a new battery, if not they it might just need a slow charge, cleaning, top off etc...

SO!

I'm out of town for a few days with no troubles before I leave...I come back and the thing is dead as a perp running from cops in LA.

I give up on the figuring out, head to Sears Autocenter to get myself a new battery, and it fires up like a dream, no probs since (knock on wood).

So I have a question for you guys...how long have your stock batteries lasted, and what (if any) mods do you have?

Steve

im still on my stock battery in a MY02 WRX. 84K - Stage 2 (up,tbe, em, etc) it has been maintained though through its life so it's still running strong. water levels always checked and filled, battery was kept clean, always charged, etc. put it on a VAT the other day and ran various other tests of the recharging system and everything is well w/n specs and looking just fine.

I used mine for about 70k miles. It was still working perfectly when i changed it out for a Hawker Odyssey MJT680 to save weight in the front.
