I used to have an old Makita drill that came with Ni-Cad a battery that eve=
ntually stopped being usable.=C2=A0 I bought a pair of lithium-based replac=
ement batteries.=C2=A0 On the surface they looked like a much better option=
with double the capacity and they worked with existing drill and charger.=
=C2=A0 But (there's always a but, isn't there?) to make Lithium batteries w=
ork in a Ni-Cad environment required a electronic circuit and this circuit =
was always on and drew enough power to deplete the battery overnight.=C2=A0=
I could charge them up in the evening and the next morning they would be c=
lose to dead.
But I see these are Nickel-Metal Hydride batteries.=C2=A0 Ni-MH batteries h=
ave characteristics more similar to Lithium - at least with regards to the =
charging regime (I've designed a battery charger for Ni-MH so I am familiar=
with this) but are less susceptible to abuse.=C2=A0 I also see the bullet =
point about no self-discharge - which was my problem.=C2=A0 This is a $45 g=
amble (as it is with most no-name stuff from the Pacific rim) but YMMV.=C2=
=A0 This might be a good one.=C2=A0 Let us know.
BTW I bought a pair of Milwaukee 12V tools and never looked back.=C2=A0 I p=
itched all my Ni-Cad drills and recycled the batteries.
