La Crosse Technology BC-700 or BC-900 chargers or BC-9009 kit.
They appear to all be the same charger.  Kit includes 4 x AA &
4 x AAA batteries plus AA to C and C to D adapters plus case.

Charger has 4 slots, each holds 1 AA or 1 AAA battery.  LCD has
4 positions to display information for that slot; you can cycle
through voltage, current, time elapsed, and mAH injected/used.
(I believe Maha C9000 LCD has 1 position and you have to cycle
 through all 4 slots to get data for 4 batteries under charge.)

I have a couple BC-900's used mainly for charging NiMH batteries.
Charge current is adjustable -- given the time I have available
before I need a set of batteries, I adjust to minimize stress on
the cells or to minimize time to recharge.  Currents available
are 200mA, 500mA, 700mA, 1A, & 1.8A if my memory is correct.
When cell is fully charged, it switches to 20mA trickle.

They also can measure actual mAH which I use occasionally to
monitor cell status.  And there's a reconditioning cycle which
I've used and seems to work.

La Crosse BC-900 charger is physically smaller than Maha C9000.

Amazon: Maha MH-C9000 is US$55; La Crosse BC-700 charger is
US$30 and BC-9009 kit is US$40.

I'm happy with my BC-900 chargers; AA batteries are decent too.

I have not had any hands-on contact with a Maha C9000 but I have
wanted to do a comparison between them -- just too little time.
