Battery ?

[Mike]

The WRX starts up and runs fine after a jump, but then wont start after
siting for awhile. Probably the battery right ? The + post was dirty so i
cleaned it off. Turns over after siting, but its real slow. Can a battery go
just like that ? It was ok yesterday, parked it last night then it barley
turned over this morning. Got a jump went to work and same problem when i
left work.

Yes

I understand that in older batteries the plates in a cell can collapse
suddenly. . Apparently 1:after rapid charging/discharge the plates can
buckle and touch,2: the plates can get eaten away and fall apart, or 3:
there can be a gradual buildup of crud till it gets high enough to
touch the plates and short them out. That discharges all the other cells
and the only option is a replacement

Yes; maintenance free batteries die very quickly. You might want to
check your charging voltage. I think Advanced auto or AutoZone will
check for free.

Definitely. Every time I get a new battery on my own it turns out to be
something else. First, remove the wires from the posts and clean the posts
and the fittings (they make a cheap tool to do this). Also, check the
ground wire and make sure it tight and clean against the body. Finally,
it's not hard to check the alternator, and you might want to have the
starter checked, too.

I had it tested at advance auto parts, it was the battery.

And what are the odds of them not telling you your battery is bad? Do you
really trust that kind of place?

Not much advantage to them not helping folks fix their cars. After all,
he's just gonna go back and complain if the battery doesn't fix his car
and prbably blab to all his friends and relatives about getting ripped
off by AZ PLUS tell usenet about it. Not very wise of AZ toy to create
such bad publicirty (doesn't mean they may not be inept at
troubleshooting his problem) besides - couldn't the same accusation be
aimed at a dealership?

Yeah , watched her do the test. Saw the bad battery message come up on the
machine. Got a new one and no more problem.
