Never had this happen.  Instead of getting a battery & rolling the dice as t=
o whether you have a short in the generator, use the battery in a vehicle wi=
th jumper cables & put a headlight in series with it. If the headlight doesn=
=E2=80=99t light when you connect the leads, you don=E2=80=99t have a short.=

I would suspect a faulty voltage regulator causing the battery to be overch=
arged.

I’d say that was an internal dead short. Nothing to do other than replace it, I think.

What is it connected to? Diesel motor? Other? Any recent changes to the
systems? Any evidence of damage from environmental, insects or animals?

I am a jinx when it comes to generators and so have participated in the
aftermath of many failures. In the past 20+ years every single time a
client had a power failure the generator system failed to power the
building. In every case the generator was started up monthly...

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.

Was it stored inside or outside?  When was the last time you looked at it 
(was there lots of freezing temps since then?)  Looking at the pics, is it 
possible that something heavy fell on the battery?  I'm not sure (from the 
limited photo) that this was an explosive event.

FWIW, I used to always buy my batteries at Walmart (this is where you got 
this one, right?)  However, a few years ago, I had problem after problem 
with the batteries and the last time, Walmart wouldn't even except the 
shot battery they sold me just about 20 mins before!  The idiots behind 
the counter didn't know how to use their tester, and they say they 
couldn't return the battery without a 'failed' test.  Note, I was helping 
someone with a car that was disabled in a parking lots so I didn't have 
time to take it to my shop and properly test and charge it.

That was the last battery I ever bought from a Walmart.  You (and others 
here) might want to take these photos and my story to hart.  8>)

Guessing here, but perhaps the battery sulfated, the plates touched/shorted=

caused internal short.=20

If the battery was not vented adequately, vents plugged, etc., it could hav=

pressurized and exploded.

I use desulfating trickle chargers/battery tenders on all of my lead acid=

Never had this happen.  Instead of getting a battery & rolling the dice as =

whether you have a short in the generator, use the battery in a vehicle wit=

jumper cables & put a headlight in series with it. If the headlight doesn=

With you 100%. At this point, I’d suggest you look for an AGM battery which will meet the specs (physical and electrical). There is just so much wrong with the old flooded plate technology (as you can see) that the cost differential - which isn’t much - is worth it just for peace of mind.

My $0.02.

I agree with the use of AGM's, but there should be a modification to the charging circuit to increase the voltage to utilize the higher voltage benefit of AGM Technology. Not necessary, but advantageous.

I will politely, partially, disagree on this one. 

If you have a battery maintainer on it (and how could you not?), you might need to buy a new one. Take a look at the specs for the one you have. I’ve used standard Battery Tender branded devices on all the stuff I have that sits (generator, 24/7/365 and motorcycle, during the winter months) for many years, with no issues. 

In terms of charging the battery from the generator while it’s running, you will be just fine.

Tom,  

Good point on the fact that the standby generator will be on battery maintainer nearly all of the time.  We are on the same page.  Using an AGM maintainer will keep that battery at AGM standards.
