5 out of 5 eggsGreat Charger

Pros: Easy configuration, large enough display, Still working (occasional use) 8 years after purchase

Cons: minor: would have liked simultaneous display of all 4 slots - rather than the sequential readout. The ability to manually cycle through the slots helps offset this (when you are in a hurry to check status on 4 cells).

Other Thoughts: I would recommend it, but there are now (2016) other units which probably have more features.

4 out of 5 eggsGreat charger but

Pros: Fast, easy to use! Does everything they say it does and does it well!

Cons: Now the but; The light on the lcd is strong enough to read a book by so don't use it in a bedroom overnight, and stays on as long as there is a battery in it. The controls while easy to set, need to be set every time you insert a battery. So if you use 2000ma AA batteries all the time you have to reset it every time (for each battery) since it defaults to 1000 after removal. A real pain in the b**t!!

Other Thoughts: I dropped an egg off this review because of my cons otherwise it would be a 5. For a $60 (with shipping) battery charger you would think they could do better. Like default adjustment or set able presets. As for the light issue. A simple software change could turn it off after 3min and a button depress could turn it on again. Come on!!

5 out of 5 eggsBest Charger Money can Buy!!!!!!!!!!!!!!

Pros: *It does everything you expect a charger to do and then some
*You have to have half a brain to use its not plug and play although it will still charge if you close your eyes and just stick in batteries.
*To get the most out of the charger and your batteries read the instructions.

Cons: None!!!!!
Some people complain about the bright LCD screen

Other Thoughts: I own 4 all bought from Newegg!!!!
It works on all rechargeable batteries.
Just don't be surprised if you find out your cheap knock off batteries or older batteries are not really 2500mah or 2400mah.
I'm charging 4 Kodak batteries that say 2400mah I'll be lucky if they hit 1000mah.
Also some Harbor Freight 2500 or 2300 at best 1900mah.

1 out of 5 eggsAVOID THIS PRODUCT

Pros: I would say price and capacity but when you read my other thoughts below you will see why I can't really say that.

Cons: Batteries only charges batteries to 80% of rated capacity regardless of the caliber of the battery you are charging.
This charger is a BATTERY KILLER and will kill off your batteries when they have only been charged a fraction of their rated charges.

Other Thoughts: Maha's solution is that I pay another 40% to have a working product because the product NEVER WORKED FROM DAY ONE.

My first communication about this defective charger was prior to July 25, 2014 about 3 weeks after I bought it and since then IT HAS RUINED 4 Sanyo Enelop XX 2400mAh batteries and 3 of the 4 Powerex 2700mAh batteries that came with the charger.

Before I bought this charger I was using cheapo Duracell chargers that I got with 2x1700mAh AA batteries for 5 bucks at a discount electronics store. They were my first rechargeables. As I started to use more wireless devices such as keyboards, mice, headsets etc I started to look for higher capacity batteries but kept using the chargers that came with my first rechargeables and NOT ONE OF THE BATTERIES that I charged in those chargers died in 3½ years. To this day the batteries that came with those first chargers (I still charge them in the chargers they came with using the PowerEx charger for my higher capacity batteries. And in the time since I bought this charger It has ruined 7 batteries (4 Eneloop XX batteries (Sanyo's top of the line batteries) and 3 of the batteries that came with charger which from looking at Maha Energy's offerings in the market are Maha Energy's top of the line rechargeables. And during this time NOT ONE of the lower end batteries that I have been charging in these cheapo chargers has ceased to function. NOT ONE and the hilarious thing is they were 3.5 years older to start with and they are still functioning perfectly and my NEWER, HIGHEST Quality batteries available ANYWHERE are being destroyed one at a time by this BATTERY KILLER.

Batteries will die for absolutely NO REASON. They may be charging a little lower than typical (which for this charger is from 70-85% of their rated capacity then suddenly they show the dreaded HIGH. This most recent one actually had a reason I guess but it's DEFINITELY NOT A GOOD ONE. I had a power bar that was switched off while the charger was charging some batteries and one of the PowerEx 2700mAh batteries that was in the charger is now showing HIGH and will not charge anymore but prior to that it was working (semi-fine) meaning it was charging to the pathetic 80% this charger allows..

And Maha's solution is for me to pay 40% of the cost of this charger to ship a product back to them to get a working product after I have already lost $50 in batteries to this BATTERY KILLER that doesn't charge batteries to anywhere near capacity even though I have been buying the highest capacity, highest quality batteries available. And the batteries that have been so murdered by this BATTERY KILLER have not even come close to the number of charges they are rated for (somewhere in the neighborhood of 20-25% of the charges they are rated for before being killed off) so it's not a matter of the batteries just outliving their useable lifetime.

You can probably hear how impressed I am with their solution.

2 out of 5 eggs

Pros: This MH-C9000 charger could able to recover some old NiMH batteries which other chargers wouldn't even recognize. For those old NiMH batteries that this charger couldn't work with, it will display HIGH on the screen.

Cons: The biggest negative is that the MH-C9000 couldn't charge the Panasonic enelopp (BK-4MCCA) batteries fully. The charger switch to "Done" too soon before the batteries were fully charged because the cut-off threshold voltage of 1.48V is too low for these Eveloop batteries and there is no adjustment or hardware update is available to fix this problem. I contacted Maha energy about this issue and they admited there is no solution to this known problem. They recommended to leave the batteries in the charger to trickle charge the batteries until full. So, basically I bought this expensive charger and use it as a trickle charger.

5 out of 5 eggsNice

Pros: Best features, works well so far.

Cons: Improvements to be made:
-Need to be able to switch off backlight since it's v. bright.
-During charging, each button could just select a slot
-But would be far superior to have all info for each slot always displayed. More $$ display, but this is a premium unit anyway.
-Have to set charge current every time; adjustable default would be nice.

Other Thoughts: Electronic products in general (not just this charger) often show too little refinement in terms of firmware. It's like they've never been tested properly by real users, or testers aren't particularly observant.

3 out of 5 eggsDoesn't Work As Advertised

Pros: It was a pretty good price for what you get.

Cons: Unfortunately I can't get this charger to charge ANY of my batteries to their rated capacity including the ones that came with the charger and that's actually a major reason I bought this charger because I was looking to buy some higher capacity batteries for my gaming mouse. I contacted these folks about the issues I was having but got no satisfaction and now after almost six months of nothing from them I'm just warning folks about what they can expect from this product and from the company that manufactures it.

Other Thoughts: I've tried all the different modes the charger offers but none of them can get the batteries charged to their rated capacity I've tried it with Duracell, Sanyo Eneloop & Sanyo Eneloop XXX and also the Powerex batteries that came with the charger but the most I could get on even the 2700mAh batteries that came with the charger was 2200mAh which was very disappointing since the reviews I read about this charger led me to believe it was a quality product.

They were wrong.
Don't be misled.

5 out of 5 eggsBest charger I have ever used

Pros: Simply the best AA and AAA charger on the market. This charger has restore batteries I thought were lost, and improved the performance of others. I had a 15 min charger which basically destroyed my expensive batteries. I have tried other cheap chargers none have the options this one does.

Simple enough for a 5 year old to use for basic charging. insert battery click click click.

Cons: A bit expensive but wroth the investment to protect your investment.

Also if you buy batteries make sure you tell your family they are rechargeable because you may find out they have been tossing them :(.

Simple enough for a 5 year old to use for basic charging. insert battery click click click.

Other Thoughts: Get a battery organizer, you'll going to need it. I bought a simple sewing supplies organizer for a few bucks, it works good to organize them.

5 out of 5 eggsWell worth the money

Pros: I use a lot of rechargeable batteries at home and with the audio system at church. The batteries in the wireless microphones were not lasting nearly as long as they should. When I tested and refreshed with this charger, I was able to identify the batteries causing the problems. I was also able to match up batteries by mAh and now the batteries last much longer in the microphones. The refresh cycle brought some of the older rechargeable batteries back to life. Some of them resulted in an error and I was able to weed out the defective batteries. Also, now I can test new batteries and make the best choice in purchasing. Was surprised at how some of the brand name batteries have the capacity overrated by the manufacturer. The Powerex batteries that came with this charger are top-notch. You can believe the 2700mAh rating on these.

Cons: Sometimes I like to complain but even if I was in one of those moods, I could find no fault in this product.

Other Thoughts: If you use rechargeables in everything like I do, you need a good charger/analyzer. Got this on sale but even at regular price, it is worth the money.

5 out of 5 eggsSaves me lots of money!!!

Pros: Great product and has saved me $$$$!

Cons: The different settings can be confusing and overwhelming. I find myself constantly referring to the manual. It is not intuitive, thus I keep the manual nearby for reference. And some settings take a long time to charge!

Other Thoughts: I got it with an extra eight pack of batteries for a total of 12 batteries. Despite the aforementioned cons, it is saving me money, and I recommend this product.
