What causes an exploded battery?

[dman4486 5,000+ posts]

There were 10 batteries lines up. Buss bars on all +s and all -s. No way they could have shorted externally, as they were behind the trim pannels and nothing else was back there to short them out.
They were always discharged very quickly, and then charged back up very quickly, but its a deep cycle and they are built to be completely discharged then recharged.

The resting voltage is 13.4-13.5. I know that isnt good for the battery, but no way it would do this to a battery. It might give it a slight bulge, but nothing like this.

Ive ran them the same way in previous setups, wired the same way, used under the same tough conditions, etc, with no problems whatsoever.

good info....imma keep watching this thread in case of someone posting a "techy" article

Why is the image I see not a battery? Did someone hack your Photobucket account?

Anyways. That would still be under warranty if they are less than a year old. As long as they are in the warranty period, Kinetik will take back just about anything. A friend of mine had a similar thing happen. His alt went apeshit and was pushing like 19 or 20 volts. He had an HC1400 and it swelled up. Kinetik replaced it no charge. They didn't even ask many questions. All he had to do was fill out some piece of paper and fax it in. They told him to recycle the bad one and shipped him a brand new one free. That is CS.

if it was only one of the 10, then I would expect it to be a build flaw in that one unit. quick discharge and recharge builds heat, and maybe you ran them to failure.

VJ changed the pic and how it shows that. What a ***. I was using his photobucket to upload the pics.

Anyway, Im not sure how long it has been this way. As for the alt, I have a Powermaster 240a I believe it is. Checked the alt, working just like it should.

Anyways, I bought some new from Kinetik and some used. The ones I bought from Kinetik were at a rediculously low price, and the ones I bought used were at an even rediculously lower price.

Im not even going to bother contacting them. I have 16 Powermaster 16v batteries to put in anyway.

If they were not wired in a balanced way (i.e. all power was coming in and out of the first battery) then this can happen to just the first few in the line. You should always connect the positive to the first battery and the ground to the last battery. If it was not connected like that, it might lead to only some of them going bad.

Or it just could be as simple as a few bad batteries. Were they all bought at the same time? Were they all the same age? If not, these things can happen when you mix batteries. Even if they are the same battery, just some were older than others.

EDIT: I see above that they were mixed ages. That could do it for sure.

Some were older. And we had quite a few places where the amp +s and grounds connected to the buss bars. Figured it would even the load on all the batteries.

how much for one good 2400 shipped to 29678 //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Yep, it was likely the age differences. Sounds like you had them wired right.

if you do not spread out the connections to your amplifiers evenly you can be making a bottle neck for current. Does not matter if you use buss bars or wire ... if you have 5 amplifiers on 10 batteries only using 2 or 4 terminals on 1 or 2 of the batteries you are hooking up your amplifiers. If lets say you have 5 amplifiers and 10 batteries you should connect an amp on every second battery ...

Not really. They are designed to be slowly discharged (10.5v is discharged) and slowly recharged.

Repeated rapid charges, especially from a very discharged state could result in damage.

I think you've found your problem.
