depends if its dry lead acid battery then it has to be replaced because all acid dryed out and no longer will help battery hold charge, if wet lead acid battery same thing all liquid acid dryed out but in some batteries like car they can be topped off for longer life usage, but if its fully dryed out possibly its going to have very low charge because it has been so dry so x ammound of time. Good question.
usually means that the alternator is not charging. So the battery is being drained.
A dead battery or a battery that has been drained.
A battery cannot be drained by a shorted diode when the ignition key is off.
dead cell in the battery or something is on that is pulling power from the battery.
It means all the electricity has been removed from the battery.
when the electronics quit working.
the positive wire that recharges the battery after being drained from the starter
Charge it, with the charger that came with it.
let's say, a battery that is drained.
Each and every time a battery is drained dead it does harm the battery somewhat. However if it was only run down once, then do not worry about it. It has taken some life out of the battery but it is still good and should last years more.
The alternator died first and drained your battery shortly thereafter.
A short circuit.
