If the battery is too far gone, hook it up in parallel with a good one and then hook up the charger. Some chargers need to "see" some voltage before they will begin charging.
Yep, I had a dead truck battery this week, and hooked up my "smart" charger to it since it was closer than the dumb one.
Unfortunately the Bat was only showing 4V, so the charger thought it was only a 6V battery. It obediently went to work & charged it all the way up to 6V, and showed full! Still didn't start the truck though.
After that, I got the dumb charger & let them work in parallel for a while. :)
