Buy a good charger that comes with discharger. You can set the discharge current & cut of at any particular Volts you required.

get a 30watt-50watt light bulb from the local 2 dollar shop, solder some wires to it and the other side to dean plugs, and connect battery. you can use a multimeter to check the voltage too if you want to discharge precisely or you can see the light dim, which is also a good indication to pull it off. careful though, it generates a whole lot of heat. i say 40 watt or 50, well thats what i use from recommended people. hope that kinda helps?

....but i would personally get a charger that offers discharge - slightly safer and definately more accurate. my other method is cheaper though

I picked up a used Integy Reactor 20amp fast discharger off eBay for $.99. They also make a 30amp version. Then I got two Trinity D-90 equalizers for $15. All feature a .9v per cell cutoff, so you know they are Nimh safe.

I always equalize before I charge...

BTW: The D-90 Equalizers are tricky cause they come with no instructions. The battery can only be inserted one way to get it to turn on. On top of that, you must insert the side with the end-bars first. Once you get it, it works every time...
