I was looking for a cheap "smart charger" and stumbled upon this charger from this page:
http://www.amazon.com/The-Best-AA-Battery-Chargers/lm/R1MD2AX62GW80A
It was the cheapest one in the list, and I had a very limited budget, so I decided to buy it and try it out. I ordered it on September 4th, and it arrived on the 10th. When I opened it, the first thing I noticed was that it was not the same charger as pictured. Then I saw on the package, "highspeed charging from 30 min" and immediately decided that I didn't want it, because I know that fast chargers are not good for your battery's health. I wrote to the seller telling them that I was returning it because I didn't want a 30 min. charger, and I recieved this response.
"The charger you ordered and received is not a 30 minute charger. Its maximum output is 600 milliamp which means that a 2400 mah AA battery (for example) will charge is approximately four hours. (If it were a 30 minute charger, it would have to charge at 4800 mah; however, this charger's maximum output is 600 mah mathematically impossible to charge a standard battery in thirty minutes.) What the charger packaging and information is telling you is that within the first 30 minutes of charge time, the charger will reach its maximum charge based on the type of battery and its condition. There is no battery that this charger will charge in 30 minutes. From the manufacturer's specifications:
THE CHARGING CURRENT: The maximum charging current per channel can be up to 600mAh or 2.4A total. The charging current is adjusted permanently according to the quality, inner resistance and fast charging capability of each individual battery.
I hope this clears any misunderstanding and that you will choose to keep the charger and enjoy it.
Thank you for your order."
So I decided to keep it and try it. I have some 2500 mah Tenergy Batteries, so I plugged them in to see what would happen. I monitored them carefully, and after a couple of hours, they started to heat up. They got hot enough that I got worried, and put them and the charger in the fridge for a while. After they had cooled down, I put them to charge again. But again the batteries began to heat up, so I put them in the fridge again. Then charged them until the green lights stopped blinking which means they are done charging. The total time elapsed was about 4 hours including the refrigeration! As it says in the description, each of the batteries stops charging individually when it is done and you can charge from 1 to 4 batteries.
If this charger hadn't heated up the batteries so much, I would have given it 5 stars. Perhaps I could just set the charger in the fridge when I am using it? :-)
P.S. See my customer images that I uploaded to see what you are actually getting, as the product description does not have accurate photos.

This charger charges batteries as well as I could have hoped. It is much faster than the last one I owned, but I wish it also had the capacity to charge the larger batteries like C and D cells. You also have to have two batteries charging at the same time, which is only slightly inconvenient. I think it will meet our needs.Best Deals for Accupower Accu-manager 2010 AA-AAA Battery Charger Charges Nimh

Even though I have only used it a few times it works great for AA batteries. But I recently bought a phone that used AAA rechargeable Nimh batteries and even though it showed they had charged them when I put them in the phone they showed they were just about dead. I used the actual phone charger and charged for 7 hours like recommended and they charged to full fine on the phone charger so not to sure about charging AAA with it. I like the fact that I can take it with me in the car and use the 12v system. My camera seems to be a battery hog so it will come in handy when I take a trip.Update. I have used this a number of times since I bought it. I even bought the same brand 4 pack AA batteries for a digital camera. I charge in pairs and it always seems like one finishes charging and then other one won't stop charging. I have used Ni-cads for years and I know when they start to warm up that usually means they are at the peak of there charge. I am not sure if I have a bad battery but it does it with another brand I have also and it doesn't help to change charging bays. I also just bought cordless phones that use AAA size Ni-MH batteries and this charger is supposed to be capable of charging them, well it wouldn't charge them. I stuck then in there and it showed they were fully charged but when I put the batteries in the phone they showed dead. I ended up having to just charge them in the phone charger.
