not wanting to buy a new battery to replace my almost fully discharged (.4 v) one i found this online. take a KNOWN fully charged bat and connect the dead one in parallel with a set of jumper cables, +to+ and -to-. connect the charger to the dead bat and charge for 1 hour. then remove the jumpers and charge the previously dead one as normal. it worked GREAT!! not wanting to overcharge by letting the trickle charger run all night i stopped last evening and i checked the v this am. lost .1 volts. on a recharge mode this am for a full charge. if successful its money in the bank.
