Default '02 OBW Battery Melt??

We just got back from vacation driving maybe 1000 miles or so and when checking the oil at a gas stop, I nopticed our battery sort of conforming to the shape of the factory clamping mechanism. It's not a high dollar battery(came with the car when I bought it), but I've never seen the battery case buckle like this one has; maybe 3/8" of meltdown?

1. Is there a chance the engine compartment(no turbo, if that's where you were going) is getting this hot that's causing this melting?

2. Any chance the alternator is over charging the battery?

3. Or is it "cheap ass battery syndrome" and it's merely time to replace it?

I have our Interstate battery in our 96 Legacy Wagon clamped down at least as tight as the clamp in the OBW, so I doubt that's the problem....or is it? We did replace the alternator with one from Advanced Auto, but again, we have an Advanced Auto alternator in the Legacy and we're not having that problem with it.

Any ideas from the Gurus would be a big help. Don't want to fry a $90 Interstate battery if there's a problem with the electrical system.

Thanks

Max

Normal engine heat, even with a turbo, should not distort or damage the battery.

The first thing to do is measure the voltage at the battery terminals with the engine running. It should be no higher than about 14V at operating temperature. If it's considerably higher than that, especially if it's 15V or above, you have a faulty regulator and need a new alternator. Excess voltage over a prolonged period will cause the battery to overcharge, overheat and vent gas and acid.
The battery itself could also have just failed, it does happen.
Once the alternator has been checked and either replaced or verified as ok, go ahead and replace the battery. Be sure to clean up any acid that may have spilled over, using a baking soda solution to neutralize it and prevent future corrosion.

Thanks. I think I'll let Advance do the alternator testing and see if they remember selling me the Alternator.

Alternator tested out fine. Battery Voltage with engine idling and no load was 14.1. With engine off, 12.05. Advanced Guru said the battery is a tad weak with full load on it, but not toast. Car starts fine and headlights seem normal, but he'd never seen a battery melt down around the battery clamp like that either. Definitely some battery fluid corroding the clamping bar. Battery's going to get replaced soon.

What is the biggest "series" battery I can fit in there size-wise? He was pushing a 35-N, but the current one is an 85. For what Advanced wanted for their 3 year warranty Gold battery, I could get the same spec battery from Interstate with 7 year warranty on it for less money.

Thanks

No Costco for 3 states in any direction. to my knowledge. Anything that Johnson Controls makes should be fine.....wait a minute, the current battery is a JC!!!! Guess I better pull it and check the sell date.
