I had a whole set of 14.4 Volt cordless tools including flashlight, small circular saw and a drill.
First the charger went, then the batteries died, and then before I could buy replacements the company then switched to the 18V format and dropped all product support for the 14.4V line.
I purchased a new 18 Volt drill from another manufacturer in protest but it really wasnÃÂ¢Ã¢ÂÂ¬Ã¢ÂÂ¢t as good as my old one, the chuck slips when drilling and the drill clutch doesnÃÂ¢Ã¢ÂÂ¬Ã¢ÂÂ¢t seem to handle torque well.
So how to resuscitate my old tools cheaply?
I had two 18V batteries and chargers from other tools and when I jumped them to the 14.4V tools they seemed to run okay. The challenge then was to convert a 14.4V battery into an adaptor.
Step 1: Step 1 Salvage
Gut the battery, removing the NiCD batteries inside and safely recycle them. Salvage the clips off the battery that serve as the connectors to the Tool.
