Won't take a charge! Yes, I know, throw it away. However, horse
person has gone off with my sound spare. Is *over* discharging an

In this case charge them double. Swine.

It is a loan! If this is going to happen again, I want to retrieve mine
before damage is done.

Horse people always seem to have contacts who supply free sound
