If you guys are famliar with the 1086 battery position you know its right under the cab.

Well yesterday I was finishing planting my neighbors beans when one of the batteries went BANG.

Didn't know what it was at first. It sure was loud in that cab with the battery right under the cab.

Thought I blew a tire.Or else someone had shot at me.

What would have caused that thing to blow?

Ran for another 4 hours on the other battery.

I have heard of a number of battery explosions being linked to low electrolyte level coupled to a high current draw. The low level exposes the plates and there is a spark between plates. Check for over charge, low acid level, and electrical short.

I have seen 3 batteries where they were internally shorted.
They were hot. Real hot.
I put on glasses and took them out of the vehicles and let it sit in the middle of now where. It would not cool down.
One was my fathers and one was my brothers and one was my sister in laws. I took the batteries out for them and told them to be carefull and get rid of them.
To think about it now I think a internal shorted battery would explode if it got the internal resistance down low enough.

A plugged vent cap can cause a battery to explode.

When I was in high school I worked at a marina in the summertime. We used an old ford 1300 to move boats around. The battery was dead one morning and a boy I worked with got the jump start box and hooked it up to start it. Well he hooked it up backwards and it blew up right in his face. I was standing 30 feet away, it sounded like a shot gun blast and I felt the concussion. We had to hold him down and hose him off real good, thankfully no permanent damage done. That sure did give me a healthy respect for batteries.

As Joe says, an internal component could have vibrated loose and the sparking inside the battery ignited the hydrogen.

1086 is starting to get pretty old - are the hold downs still in place? All it takes is a good bump and both poles could make contact with the housing. My brother did that with an old pickup. Didn't blow up the battery but it did leave weld marks on the hood and roasted several electrical parts.

Yes holds were in place and still are with the top molded up around the hold down rod.

Bent the rod also.

I blew one up on my 2-105 last year because I was stupid enough to short out one of the post while I was trying to disconnect the battery so I could take off the starter. It only took on split second for me to accidentally touch two post together with a box wrench and it blew up in my face, good thing I always wear sun glasses.

No, it wasn"t shorting it out - although that should have been avoided by removing the earth lead first and using a short spanner which will not touch both terminals at the same time.
Your failure was removing a battery which had just been charging. A battery which has been vented and not charged for just a few hours will never explode. It is only the recombination of hydrogen and oxygen inside the battery that causes the problem. No charge = no hydrogen and oxygen produced; venting = hydrogen escapes and disperses in the atmosphere. Interesting point: there is no hydrogen in our atmosphere - any that is produced will eventually escape to space as it moves so fast.

Be thankfull it was under the cab. I had one go off between my legs. I actually heard the hissing and looked down as she went. Between the acid in my eyes and the plastic chunks in my face, it was a long hard trip to find a water hose.

The battery probably had a corroded battery terminal or a plate in the battery broke loose. A small spark there caused the hydrogen gas to explode.

Haven't got a bad connection on that battery, by chance?

Something sparked it off while it was gassin' hard.

It could have been a spark.

The planter monitor,planterfold controls and my GPS are all tied in on that battery. So anyone of those could have had a bad connection.

But everything still worked after the BANG and it didn't coinside with flippin any of the switches.

This is the 1086 I just put a new alternater on about 20 hours of operation earlier.

Your new alternater is not overcharging is it? If it was it would cook the batterys causing more explosive gas to be emitted making an explosion more likelly.
