Unbelievable quotes.....

[Peter Dunkley]

Again not airgun related but was on a now not much used airgun forum.

Guy said he had a friend who replaced the battery on his car with a higher amp hour rating and burned out all the wiring.
He also claimed he could rejuvenate knackered 12volt vehicle batteries and that his system was so good that he had a contract with the army to do this to all the old batteries and they were then returned into service.
He was serious.

Lots of other crazy claims but these two were the worst.

Now that's quite interesting actually, because to a curtain extent this could be true... Batteries in curtain instances where they haven't been charged correctly ever ( like via the single stage charging that a traditional alternators offer) can be brought back to life with proper 3 or 4 stage charging systems. Admittedly this isn't fool proof and it does depend on the type, build, & chemistry of the battery (most likely to be achieved with expensive maintainable lead acid cells because the plates are thick, the acid can be replaced and the sediment washed out) but there is some truth in this.
I've had an expensive 12v AGM stater battery be discharged down to a resting 3v before, (which as far as lead acid goes usually means off to the graveyard at about 9.8v) come back to life and offer years of good service after that so I think it's often thought through lack of knowledge that alot of Batteries are dead before they really are...
Interesting stuff!

Ps the amp hr thing is definitely BS!! Lol
