Hello all,
I have multiple Makita tools, all of which use the 9.6V, 9000 battery.
I know that it is just 8 sub c cells all stacked inside a housing.
Is there anything that would prevent me from cracking open the housing
and replacing the batteries? They are aging a bit and not providing
much life. Would replacing them with Ni-Mh cells confuse the charger?
Thanks!
Justin

Lack of a soldering iron, probably.

No, but it might ruin the batteries. IIRC, NiMH and NiCAD use very
different voltage and amps when charging. Stick with the NiCADs...

That case is made to close tolerance and thermally sealed; I believe that
was with the intention of preventing what you're trying to do. Replacements
at $30 each make it not worth my trouble, as I get about 3-5 years per set.
You _can_ get the NiMH batteries and charger to use with the tool, but
charging rates and feedback circuitry are too different to cross over.

After picking up a "fancy new" 18V drill...I decided a 12V Makita
was plenty. I have not been dissapointed.
However, I must admit that I have a 1/2" Milwaukee that I pull out for
big jobs. Usually, it is more of a logevity issue, rather than
power...such as 170 1/2"dia holes I drilled in oak this weekend.

I had the same problem with my old Makita. Both batteries no longer took a
charge at nearly the same time. If I was going to replace one, I had to
replace both. I took one of the batteries apart to try what you suggested.
I messed around with it for a while and finally opted to pitch it all. New
drills are cheaper than the two replacement batteries. I opted to get a 18v
in its place, for not much more money. It's been worth it to not have the
agravation.

I actually did this to my dewalt batteries a month ago. The soldering
was a PITA because of the connections. I had to get the right size
cells at a battery store but they work like new now.

Thanks for the advice :-) The drill is not as powerful as the fancy
new ones anyway, maybe it is time for a replacement as you suggested.
