Reviews Summary for MH-C801D Deluxe Professional Charger
MH-C801D Deluxe Professional Charger Reviews: 4 Average rating: 4.5/5 MSRP: $85. Discount retail is LOWER
Description: PowerEx Launches a Cutting Edge 1 Hour Eight Cell Charger

La Verne, CA - August 12, 2005 -- Maha Energy Corp., the maker of PowerEx batteries and chargers, introduces the MH-C801D Eight Cell One Hour Charger. This international, high-performance charging system refreshes old and degraded batteries and makes charging easy.

The MHC-801D features eight independent circuits that charge one to eight AA or AAA batteries in any combination. It’s like having eight independent chargers! The charger incorporates a large LCD screen displaying the charging status of each battery. The English-language-based display replaces traditional LED indicators.

Maha Energy’s team of engineers developed a brand new Eight Cell (0.001V resolution) microprocessor. This microprocessor will charge batteries to their maximum capacity without overcharging or undercharging… delivering true precision!

The MH-C801D provides the option to choose between a soft charge and a fast charge mode. The soft charge delivers the highest battery life and allows 100% compatibility with older, lower capacity batteries. The fast charge allows eight batteries to be fully charged to their maximum capacity in as little as one hour!

The Eight Cell charger is embedded with a high-rate battery conditioner that will charge, deep-discharge and recharge batteries automatically for maximum rejuvenation. The cycle restores the batteries to their optimal performance level minimizing any memory effect. Batteries that were previously thought ready for the recycle bin can be brought back to life.

The MH-C801D intelligent system will charge batteries anywhere around the world with a heavy duty switching AC Power Supply. This 100-240V, 50/60Hz universal adapter employs a rugged DIN connector for reliable contact. The MH-C801D is perfect for home, office or travel.

The MH-C801D charger’s MSRP is $84.95.
Product is in production.

A must have charger for AA/AAA's  Time owned: more than 12 months
I use my Maha MHC801D almost daily, since almost all my portable ham gear, photo gear, and camping gear run on AA's or AAA's. I have never had a problem with it. Love the fact it charges a mixture of 8 cells simultaneously and keeps you abreast of progress on each cell individually. (I use 2500mAH NiMHs). The small fixture sits inconspicously on a table, ready for action. Now I always leave the QTH with freshly charged batteries. Best charger I have ever own.... and I have had many.

Great charger small LCD  Time owned: 6 to 12 months
I bought this about a year ago and I am glad that I did.

The Good! I works well and it has a battery exercise setting that restores batteries with the memory problem pretty well.

The Bad. It doesn't do C, D and 9 volt batteries. (I understand that they have one that does AAA-D cells now).

The ugly. The batteries get very hot in fast mode and the LCD can hardly be read by a person with good eyes.

Overall. It really works well

Very good, very expensive.  Time owned: 6 to 12 months
I bought mine about 8 months ago and found that it worked very well. I use rechargable batteries instead of a battery pack in my Icom T2H and this is an excellent way to keep them charged. My three complaints are the the batteries get very hot in the fast charge mode, the power supply for the charger is large and clunky and that the product is extraordinarily expensive. $85.00 is a LOT of money for a battery charger.

Maha's Next Big Thing  Time owned: 0 to 3 months
It seems to work well. Maha seems to have learned a few lessons from their earlier chargers, which honestly, weren't as good as they could be.

This time they seem to have started with a clean sheet of paper and as far as I can tell seem to have a well thought out product. So far I am impressed with this charger.

This charger charges AAA and AA cells, as few as one, as many as eight. Each cell appears to have it's own monitoring, Maha asks that you group different type cells together.

This charger has a "soft" mode which causes the charger to charge (and discharge) the batteries at a slower rate at the cost of longer recharge time, but providing longer life. This is a good thing, something earlier charger such as the Maha MH C-777 lacked. Although it charged the battery fast, it trashed it fast, too.

I have tried charging 1800 ma/h and 2300 ma/h AA cells in "soft" mode with no overheating issues so far. The batteries do get quite way too hot in "normal" mode, which supposed to charge at a 2 amp rate. Way too fast for my taste. I checked the batteries charging with an IR thermometer and they were running 190 degrees. Ouch! Maha suggests using 2000 ma of larger capacity batteries in normal mode.

A word about the power supply, it's switching dual output "cord wart" that's is rated at 2000ma at 18 volts with a second output rated at 20 volts at 300 ma, a total of 42 watts, which should provide adequate power to charge all 8 batteries a 2 amps each, or just a tad over 22 watts of power. It doesn't get warm, but is somewhat electrically noisy in the lower HF bands-especially when there is no load on it (no batteries charging).

Pros: It can charge any number of AA or AAA cells up to it's capacity, it does a good job reconditioning batteries, it has a great display that shows the charge mode of each individual battery (discharging or charging), and has a slow charge mode for preserving the life of your batteries when you aren't in a hurry.

Cons: RF noise generator, display somewhat cryptic, operation isn't straight forward, and in the normal mode may change lower capacity batteries way too quickly causing overheating.

I am rating this charger a 4, the only reason it's not a 5 is that I feel that the fast charge (regular) mode should be selected, not automatic and "soft" mode should be the normal plug and run mode.
