I could be wrong, but my guess is that power pak battery is a lead-acid gell cell. If so, it is similar to the one in your car, but is sealed and uses a gelled electrolyte so it is less likely to leak. Lead acid batteries are not normally intended for deep discharge and may (or may not
) be recoverable if completely drained. If it is a lead acid gell cell, you may be able to use a charger designed for automotive applications to re-condition it.
When time permits, I will have to disect the unit and determine the best method to try to revive the battery with the tips you guys have given me. Thanks. I had a FireStorm 12v cordless drill that both batteries will not hold a charge more than a few hours. I tried freezing one of the batteries, once drained, then tried to charge it. Now it is totally dead. $30 a pop for batteries is a little salty for my blood. There are people selling, on ebay, some kind of method of resurrecting the dead batteries. One method is to replace all the 1.5v rechargeables inside the unit. My as well buy a new battery. I will keep my eye opened for a reasonably priced B&D 12v battery but in the mean time, I picked up a inexpensive Great Neck 18v Variable speed drill for $20 and a second battery for another $10.
Oops, you have one of the marlboro power Paks. Is the only way to charge it with the 110 adapter ?
