So it is possible for this charger to have a 4 slots 2 Amp contineous output. Hey Tyco,

The charger has a 12 Volt 2.0 Amp input, and 4 times !!2 Volt!! output 2.0 Amp. So it is possible for this charger to have a 4 slots 2 Amp contineous output.

I used to have BH-900, which I accidentally fried by connecting it to wrong transformer. This unit overheats and overcharges batteries thus decreasing their life. A hint should be that the adaptor with 2A cannot in anyway provide 2A for each slot by any other way but pulsating the current. So f.g. by choosing charging current of 500mA, you will end up having current pulses from 0 to 1500mA. Re-flex charging is excellent thing, but the max charge peak should not exceed the entered rate by that much and not that often it heats up the battery. Other charger I have (for rc-models) is Duratrax ICE and it's reflex charge is like it should be. At 500mA charge, it peaks to 1A for a half a second every minute or so. This way the battery won't heat up at all. This unit will be hidden in the dark corner of closet and BH-900 will be ordered in, since I use rechargable batteries quite a lot, I kinda like them to stay in shape for as long as possible.

Guess what Robert [author of this article], your precious BC-900 [version 33] is prone to going up in smoke. Versions 32, 33 and to a lesser extent version 34 have been reported to literally melt batteries and some of these bc-900 chargers themselves have melted. Fire hazard indeed. There is now a version 35 available and although there have not been any public reports of this particular version causing meltdown issues, just wait. The toasteroven complex generally rears its ugly head anywhere from a the first week of ownership to 2 yrs. down the road. If your version 33 has been flawless, count yourself lucky. Another serious issue with Lacrosse is their customer service. Terrible...and that's on a good day. Steer clear of Lacrosse if you value customer service and reliability of products. Last but not least, Lacrosse Bc-900 algorithm used to calculate/display your lovely mah ratings/voltage is not as accurate as the Maha c-9000. So, you're welcome to believe those numbers on your screen if you wish. This is not to say Mh-C9000 is without issues, such as repeating digit [in cycle mode = fixed in 2nd version]. Termination problems [in charging mode = fixed in 2nd/3rd version]. AAA batteries sometimes not making proper contact, or losing contact. The negative AAA terminals need to be adjusted forward. This issue has yet to be resolved. Yet, at the end of the day...I'd rather have a product that doesn't have the history of melting down, nor a history of crap customer service, like Lacrosse. So...don't be blind man..open your eyes and look at the pros/cons of all products. You, unfortunately have chosen the lesser product, simply because you own it. I find this very amusing.

It wasn't clear until later in 2007 that the new firmware was actually released in March 2007 with serial numbers beginning with OG. Maha chose to be low-keyed about the firmware rev. They did not and have not released any information on what changes were made or when they were made. A mistake, in my opinion. All the information available was hearsay. As stated above, I didn't retest and don't plan to retest the MH-C9000 because there are other things I don't like about it. Do your own due diligence and make your own choice.

For the last hour I've been reading that thread about termination problems thinking that it is indeed a problem with the MH-C9000. When I ended on page 20 the thread stopped, with a last post in February 2007. I wondered why that was so I searched for all posts with 'MH-C9000' in the description and it turns out that Maha actually solved the problem in February and none of the MH-C9000 builds since that month have any of these terminator problems. Since that period I read nothing but very positive reviews about this product and in the majority of the people think it's now better than the BC-900, again - based on what I read on that forum. So I think I was fair to think that you should have tested with the new build. You have never done this and because of this you've given your visitors false information. You have also compared a brand new model with no major updates to BC-900 which was much more mature, had received much more updates, which is like comparing apples with oranges. Why, because you're so in love with LaCrosse BC-900 and want to make the MH-C9000 look bad, like childish MAC users want to make Windows users look bad? And as for the 4 slot display that it's missing; true, but not really important, it doesn't make the charger perform better on the BC-900 in any way and that's what people actually buy a charger for. “The MH-C9000 has an issue with charge termination – discussed in depth on the CandlePowerForums.”

Firmwares are there to improve things. You do recommend the La Crosse, but only with...and here it comes... 2nd generation firmware...doh! You don't make any sense. “Update June 1st: I have no intention to retest the Maha MH-C9000 with second rev firmware”
