The Maha MH-C9000 WizardOne is going to be my favorite charger--that much I know. I've always wanted a charger which displays the available capacity of the batteries because it allows not only battery match to extend the life of my battery collection, but also informs me of batteries which are on their way out and should not be used with other batteries. Four completely independent circuits control each battery and determine the proper charging and discharging rates.

Heat is certainly not an issue if you let the MH-C9000 determine the proper charging and discharging of your batteries. In fact, my AA 2700mAh test batteries were actually cooler than they've ever been. You can increase the charging rate of the batteries, and this is definitely a great feature of the MH-C9000 which I am sure many will use to speed up the charging and discharging for special emergencies where power is needed as soon as possible.

HIGHLY RECOMMENDED

I noticed a few cons, but one really stuck out in my mind and irritated me. One of the best features on the MH-C9000, the time elapsed display, ONLY shows the time elapsed for that particular charging routine. As noted in the review, there are several charging routines within several major modes of the MH-C9000. So, this effectively renders the information useless. I'm hoping Maha quickly re-designs the MH-C9000 so that at least we have a TOTAL ELAPSED TIME available. I will say I'm glad Maha decided to keep with the backlit LCD and even made it larger this time around. Kudos on that one.

After having a few packs of AA 2700mAh NiMH batteries in storage for about 6 months, I decided to test them on the MH-C9000. Well, it performed flawlessly. I was very impressed. The approximate 10% battery capacity which was lost over these 6 months sitting in a box, was reclaimed using the MH-C9000 in the IEC standard Break-In mode. The typical Refresh & Analyze mode is not enough for batteries left unused over 3 months (and Maha states as much in the user manual).

So, should you buy one of these? Hell Yes. This device brings a new era to battery charging and come to think about it, brings the control back to YOU, the person who uses the batteries, versus other charging devices which simply tell you with a green LED if the battery is ready, and amber or red if it is not. Now you can finally be a productive power manager of your electronics components because the MH-C9000 gives you the dynamics no other charger can provide.

Maha MH-C9xxx For C and D Batteries? Other versions?

I suspect we will see the Big Daddy of all chargers in not only AA and AAA, but supporting C and D batteries as well. Of course, this won't be cheap and I suspect if in fact available in the future, it will be roughly twice as much as the MH-C9000. However, considering the obvious features of being the center command console for virtually all your batteries, I wouldn't have a problem with the price. For now, the MH-C9000 will satisfy most users as AA and AAA batteries are the most commonly used in electronics.

What I also look forward to, is possibly an 8-AA/AAA version, which would really be nice, especially for those photographers out there who have multiple flashes and those who have multiple remotes still lying around.

Where To Buy Maha Chargers?

I've been emailed a few times on just where to buy Maha chargers and the response is always the following: go to Thomas Distributing. They have the best selection at the best possible prices. You can also go directly to their Maha MH-C9000 page. I've been dealing with Thomas Distributing for many years and they are the only place I purchase my batteries and equipment from. They are also one of the very few businesses I will be completely confident in recommending to all my friends and DigitalDingus viewers.
