little background... battery is in a 30kw Generac standby generator. Protected
from the weather
It exercised itself last week with no problem..
cables and connectors were clean and tight. It was 2 years and 2 months old...
generator is equipt with a trickle charger that keeps battery topped off and
I've never had a problem with it. I think it's rated at 1 amp.
took the battery back to Walmart and it was 2 months out of a 2 year warranty
and they said they would give me a core charge ...nothing else, even though it
EXPLODED !!
I'm gonna wash the generator down with baking soda today. Signs of sprayed battery acid are evident everywhere. Then do some testing...
I'm
with dirtbeard...I'm leaning toward internal short as I've seen lots of the
same thing on the net with Walmart batteries.....more to come

Guessing here, but perhaps the battery sulfated, the plates touched/shorted and
caused internal short.
If the battery was not vented adequately, vents plugged, etc., it could have
pressurized and exploded.
I use desulfating trickle chargers/battery tenders on all of my lead acid
batteries in hopes to extend the battery life and hopefully to prevent this
scenario.
Again, though, just guessing here.

Never had this happen. Instead of getting a battery & rolling the dice as to
whether you have a short in the generator, use the battery in a vehicle with
jumper cables & put a headlight in series with it. If the headlight doesn’t
light when you connect the leads, you don’t have a short.

trouble shoot till I get another battery... what...other than a direct
short would cause this?? what/where/how would you troubleshoot ??
