I bought a complete kit of cordless tools at an auction. The tools do work but the batteries are nearly dead. They are 14V. The kit was used, but complete except for the battery charger. Later in the same auction I bought a cordless drill, also 14V but a different brand. That one has the charger. The batteries from the first kit dont fit in the charger, but I opened the charger and it would be easy enough to run a few wires out of it, and I could easily make a wooden thing with a few pieces of copper strapping to make contact with the batteries. Of course I know the polarity must be correct.
My question is whether these chargers are all the same as far as current (amp/miliamp) output? Obviously the voltages match, so is there any reason not to do this? You dont need to give me a speech about safety. I know to do the work with the charger unplugged from the wall outlet, and how to check for proper battery polarity with a meter.
Thanks
