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

Hi,
There are few different kind of batteries with diferent characteristics
for charging. If they are same kind, why not?

So how does one determine what kind of batteries are in the pack?

Not very likely. Also the required charging charastics of the
batteries may be different.

Cordless tools typically have nicad, or lithium ion batteries. If the
charger and the tools are both nicad, it should work just fine. Or if they
are both lithium ion.

Might be worth buying one tool to get the charger, or maybe find another
charger on Ebay. I had a look a while back for my 14.4 volt Miluakee drill,
and folks are selling chargers on Ebay. If you got a good price on the
tools, maybe just go buy another charger?
