Here is one article about causes of battery explosions. Plenty more out there. Don't need any more opinions about causes. Engineers have it all figured out.

There are two primary ignition sources that you have to worry about, and they can both be avoided with careful charging, jumping, and maintenance practices. The first ignition source is a spark created when connecting or disconnecting a jumper or charging cable. This is why it’s so important to connect to bare metal on the engine or frame instead of the battery. If you hook up the negative jumper cable to the battery itself, any lingering hydrogen may be ignited by the ensuing spark. This is also why it’s a good idea to wait to turn on or plugin, your charger until after it’s connected.

The other type of car battery explosion still involves hydrogen gas, but the ignition source is inside the battery. The issue is that if a battery isn’t properly maintained, and the electrolyte level is allowed to drop, the lead plates will be exposed to oxygen and may warp. This can lead to the plates flexing and touching during the extreme current drain initiated whenever you crank the starter motor, which can result in a spark inside the battery. That, in turn, can ignite any hydrogen present in the cell, causing the battery to explode.

The plates can only touch if they don't have proper insulators between them.
I read both linked articles and they sounded about like the articles I've read about how dangerous Corvairs are and the sections about internal sparks were obviously from the same source. I would take a well thought out post on here from some of the intelligent experienced members we have over those articles.

Anyone can read what they want and interpret to meet their opinion. Batteries are dangerous.

Yes, Batteries CAN be dangerous.

Story about a young man killed because he was charging his smartphone.

Use common sense around automotive lead/acid batteries - definitely put the last ground connection on metal away from the negative battery post.

Careful around those bed-sheets and bathtubs, too!

I can't even begin to count how many Lithium batteries there are around here.
Still kickin' though...

New battery works great, I tracked down the short to the hot red wire under the dash that I never connected to the lighter terminal...it must have been making contact with something. I added a fuse (15A) so that's all set. The reason I had it disconnected in the first place is because I wanted to add a fuse but just forgot. Now my alternator isn't working...no doubt a casualty from this whole situation...I'm assuming the alternator should have more voltage than 12.5 (same as battery) It should be 14.5 ideally. And still not sure why every time I depress my brake pedal my left blinker light comes on...oh well, first things firs...alternator

Dan most of those type incidents come from something they call thermal runaway, the battery gets hot and basically runs away, keeps getting hotter until whatever it's mounted in catches fire, lost a bucket of money for Samsung on cell phones.

Speaking of battery explosions - In high school auto shop (Note - I am 71 years old) We were charging a battery on an engine test stand, when I removed one of still electrically hot cable clamps from the charger to the battery post, about 3 inches away from the caps on the charging battery. It was at that moment I learned two valuable lessons. One, the chemical effect of charging a lead acid battery - Hydrogen escaping (and looking for oxygen) - and two, never connect or disconnect a live cable to a battery post (spark!). Since then (50 years) I have charged hundreds of battery and never look up a live feed from a charger. I also believe that is the reason that most cars now have a "post" to connect up a jump start, rather than hooking to the battery.

Yep, most everything I remember in the military had remote jump start locations.

The battery actually makes hydrogen and oxygen from water.

My brother taught me to always blow across the battery before disconnecting the charger clamp even after turning the charger off. He said there's still a possibility for a spark, he also worked at the boat shop with the battery top stuck in the ceiling, may have been a witness.
