Thanks, David. The Amazon listing indicates compatibility with the =
original charger and several reviews say they had no trouble doing so. =
It is a $40-$50 gamble either way and I have too many projects at the =
moment to add rebuilding a battery pack to the mix. I will give the =
Amazon pack a try and report back.
Jim
p.s. I switched to Milwaukee battery tools, as well. I started with the =
M12 set and then added M18=E2=80=99s as well. I especially like the =
fact that one charger will charge both the 12v and 18v batteries. I =
still have some of my old tools and have bought a couple of adaptors to =
be able to continue using a few of them with the M18 batteries. They =
are reasonably inexpensive and work very well. I wish I could do that =
with the Bosch saw, but no one make one and, while I could probably rig =
something using the old pack, I don't want to risk burning out the motor =
running it at only 18 volts.
