battery problems

I tried to start our truck, when I heard a strange noise and smelled something funny. I got out of the cab and saw a bunch of smoke up out of the battery bay.
The truck has a 24 Volt system running 2x 12Volt 88 amp batteries.
The connector cable had come loose on one side - and simply melt the battery pole down! In fact - there is a hole now where the pole used to be!!
I swapped an identical battery from our fork-truck and drove to the shop. They told me that I was fortunate that the battery did not explode!

So - the LORD allows some things to happen, and prevents other things from happening!!

(might want to remember that when you are prompted to want to ask: "Why, LORD?""
