Sudden death of battery

As I posted I got ran over last month. And have just repaired, repainted and assembled my ride. Battery sat for a month but started just fine. I warmed it up, rode it to the back and shut it down. 10 minutes later I tried to restart, nothing, no; lights, clicking, horn, etc. I checked fuses, connections both sides. Put a meter on the battery, .24 volts. Thought my meter was bad, so I checked my truck. 12.9V. How can a battery go from perfect to nothing in 10 minutes? No smoke, shorting anything. Never seen this before. Usally the go bad slowly.

They can do that, probably broke a plate connector inside, if it's actually gone. How old is the battery?

Did it take a lot of cranking to get it started? That can overheat the lead plate connectors and melt them.

Garage
Is it the same battery that was installed at the time of the accident?

if so, I am not surprised that it suddenly went from charged to dead.
Internally, something must have been jolted and cracked....and heat expansion broke the connection.....it happens.

That is what I decided. Broke from hit, but was still connected until current flowed.
