It tells you more than you will ever need to know about all types of
batteries, how to charge them, how to discharge them, what the chemical
makeup is and loads more.

It reckons that you should not let lead acid batts fall below 2.1V per
cell (12.6V) in an ideal world.

Sounds knackered to me. I had a car battery that went flat after being
left and it was never right afterwards, it did like you describe.
