I'm still holding off...heard too many firsthand stories of chargers

You'd be very well advised to check into those stories before placing too
much confidence in them.


Most recent story of just a couple of months ago--JD dealer here has
started carrying Milwaukee, Makita, and another one or two in new
dealership showroom besides the Green-branded stuff (the maker of whom
for them I'm not positive--need to ask Russ about that). Anyway was
looking for the LED lantern attachment to go on the existing Milwaukee
NiMH packs I have for winter backup power-outage lighting relief and
didn't have any for them, only the Li. So that naturally go to the
discussion of same and he mentioned he'd had three packs overheat and
nearly start fires on different tools/manufacturers and they had also
had trouble with some in the shop. So his take was "don't leave them
unattended" -- mine is "not taking a chance" at least yet.

I find that very hard to believe. Very hard. Dealer's stories are not all
that reliable. Especially if the dealer is older or fixed in some older way
of doing business. You really don't think this would be more well
publicized if it were really true?


I don't know what the difference really is but there does seem to be a
fundamental behavior in that they have a much higher probability of
thermal runaway occurring.

No, it doesn't.

Fair enough.

Especially if he has old stock of nimh or nicads that he wants to push out.
