Does anyone know how to change (I'm guessing this is a 'typo' - should
read "charge"?) a Makita 9.6 volt battery charger made for NICAD's . I
want to be able to charge 9.6 volt NiMH in it and it refuses to work.
The NiMH battery has the same physical dimensions as the NICAD >
By "refuses to work" what do you mean? Does it not charge at all, or is the
charge rate too high/low?
Try:
http://www.powerstream.com/Ni-Coin-ceLL.htm for a good rundown on the
type of charger you need. Probably a p/n PST-5830-8 will work?
There's also a lot of information on the same site about charge/discharge
rates etc. (usual disclaimer - I have no interest in the company).
A "trickle" charger can be easily built from a junked walwart with a
dropping resistor to limit the charging current to what you need. Not too
sophisticated, but will do the job if you watch the amount of time you leave
it plugged in (i.e. don't leave it on charge for weeks at a time
Hope this helps. If not, drop me a line (delete the obvious) - I've made
several inexpensive (read "cheap") chargers for small NiMH batteries to
replace original NiCad packs.
