OK, before I go any further, this tip is probably extremely dangerous, so I only offer it for those brave enough to try it.
This weekend I have got some jobs to do on the van, which require the use of my trusty Black and Decker Quattro. I dug it out from under the huge pile of junk in the garage, and got the battery and charger to give it a full charge.
The charger went straight to fully charged! Thinking this was unlikely I tried to use the drill, battery totally dead. So connect it back to the charger, which instantly shows that the battery is fully charged.
I did some google research, and found this tip. What you do is identify the positive and negative poles on the battery, next connect a car battery charger to the correct poles on the battery, and leave it charging for about 5 minutes. Now connect the battery to the proper charger, and hey presto, the charge cycle begins!
I am led to believe that this works because a NiCd battery develops crystals internally if not used for a long while. This technique dissolves them? As I said, probably not particularly safe, but it saved me £50 for a new battery.
