This might sound like a stupid question but I have several 14Ah lead acid batteries that i accidently left energising a relay and checked them recently. They all read between 0.5v and 1.5v which I know is very bad for this type of battery, and thought I can still charge them but they don't draw any current from the charger now. Why (chemically?) don't they charge anymore? And is there any way to bring them back from this?
