Here are some tips I use to charge a dead battery. If the battery won't take a charge and all you get is error messages on your charger, Hook another fully charged battery in parallel with it. (+ to +, and - to -) then hook up the battery charger, often this will enable a charge to feed into the uncharged battery. Leave it like this over night and ususally the dead battery will pick up a charge. If this does not work, if the battery is a wet cell battery with battery caps, you can pour all of the old acid out and reacid the battery with new acid. This will bring about 1/3 of the batteries back to life. If the battery has a short or a real dead cell then about all you can do is trade it in on a new battery. Be sure to thouroughly clean both terminals before you use the battery. Desulfinating a battery will usualy add another year to its life. Equalizing a battery will also help, but you can only do that with a wet cell battery.
To boldly go where no one has has gone before, You usually find out why.
