[Chevelle-list] AC Delco Battery (off topic)

[KW]

Usually it is the battery cables that cause the post problem (or at least contribute to it). There is a lock washer (if memory serves) under the bolt on the side post batteries. The washer deteriorates  (crushes or acid takes it's toll) and the bolt runs further into the battery before it gets tight, unfortunately the bolt hole isn't deep enough and the post cracks. Easy enough to fix, just remove the bolt from the cable and either shim the bolt with a new washer, or trim the end of the bolt.
YMMV, but this is what happened to my '02 Duramax..... BOTH batteries GRRR. Shimmed the bolts and have had no problems.

  Has anyone else had problems with leaking AC Delco sidepost batteries?

  I had 2 replaced in my 99 Chev truck, first one was under warranty, the second was on my dime, went to an Optima Red Top after that.
  The leaky battery ruined the positive cables and made a mess of the battery tray and frame rail.

  I replaced the one in my C5 vette before it had the chance to ruin anything. Put in an Optima there too.

  Today I pulled the back seat in my wifes Bonneville SSEi and that sob Delco had leaked and ate up the floor pan and made a mess out of everything.
  The positive post pulled right out.
  This really sucked with it being under the back seat, battery acid nice and close to the carpet, upolstery etc.

  Now I need to find a replacement that is configured with the gas release vents that go throught the floor pan.

  Thanks,

  71 SS454 with a Red Top too.
