battery detonation

It finally happened. After 3o years of managing large electrical distribution systems with very large dc back up battery systems and 45 years of car battery use, I had one explode in the rv yesterday. Detonation was loud enough to where it upset the wife inside the house 100 feet away.
one of the two battery, house rack internally exploded spreading plastic and acid. We had just finished a three day trip with utilities at the campground and at the house reconnected for charging maintenance. Every three months, I check levels and adjust with distilled water only. Batteries were two years old and required water only once.
I will take both back to interstate battery and ask for a discounted replacement and Interstates recommended test for charge maintainer. The distributor is good folk and will do what's right.
I guess the message is batteries do explode and when working around them personnel protection is important, along with ventilation, spark reduction etc. Googling the issue, that explosive force is similar to a stick of dynamite with acid spray as a kicker.

stuff happens
  • It happened to me when I was doing my routine startup in the winter. When I spoke with a tech about it while looking into another issue he said it is not that rare.
    His take was this. Battery s low on water due to age and constant charge. Gas developed in the void, any small spark will blow the works.
    let's be careful out there.
  • It happened to my wife 20 years ago while starting her car. There was not one piece of the battery left that was over two inches long. When dealing with hydrogen gas, a single ignition source such as a spark or cigarette is all it takes.

    I appreciate that yours was internal to the battery, but it's a good reminder that if you keep your batteries in an enclosed space, it's important to make sure that there is good ventilation so that an explosion won't occur within the confined space of the battery storage compartment.
  • Sorry to hear about what happened to you and your coach! In my lifetime I seen one battery explode and it was scary! I was 17 years old working at a Signal Gas Station, when my co worker went over to check on a battery he was charging. My co worker was smoking when he bent over to check the battery and it blew up!
  • I found this in my RV two months ago.



    I also had a battery explode years ago when I was working at a gas station when I was a kid. It blew battery acid all over me. Fortunately I was at a self service car wash when it happened and I was able to immediately rinse the acid off my face, arms, chest. It sure did make a mess out of my cotton T-shirt.
  • and they can do that without even being on a charger. Had one across the street in a car. People had been gone a full week and when to check on the noise and found the same thing.

    Could you tell us what converter/charger unit you was using. Also type of battery 6VDC or 12VDC
