AccuPower IQ-328 Battery Charger Analyzer Tester AA AAA NiMH NiCd

I have two other more expensive chargers but they don't work any better than these. I liked it so much, I bought a second one. The first one I've had almost 2 years now and not a glitch or missed cut off. I chose this model because first, the low price and second because of the higher charging current capabilities. The higher capacity batteries would take all day with other chargers. These have the 1000mA x 4 or 1800mA x 2 capability plus everything else as described. Four independent and separately controlled slots is great because I have AAA batteries as well and some devices use 1 or 3 batteries. Charges each battery to whats needed plus checks capacity and reconditions as well. Everything you need and want in a charger and nothing else. Has worked great with all brands I have (Duracell, Energizer, Rayovac, Sanyo, Tenergy...) Bought with Sanyo Eneloops' and all were shipped fast. Definitely recommend this product and seller.

I bought this after reading reviews about rechargable batteries and chargers untill my head ached. I figured out that was futile, and I couldn't go wrong just going by what Nlee The Engineer recomends. I still think that's great advise and want to thank him for taking the time for all his great reviews and I hope it doesn't seem like I'm second guessing him. I bought this when his earlier reviews gave it 5 stars. He's since lowered it to 3 stars because of problems when charging 4 batteries at 1000mA. I might have bought a different charger, but I'm really happy with this charger. I've got 32 Enellops and a bunch of older Rayovac and Energizer AA batteries, so I use the charger a lot. I'm not nearly as smart as the smart chargers, and have only used the charge and refresh modes. I use 500mA most of the time and ocassionaly 700mA. I couldn't be happier with this charger and the Eneloops. It does what I need it to do, and was priced right.

I've had several AA / AAA chargers over the years and even converted some hobby charger to test suspect batteries. Last decent charger I bought was a LaCrosse BC500 that lasted 1 year before the display went bad. After reading up on this charger that has been sold in Europe and the UK over the last year I decided to give it a shot as it had excellent reviews. Very solid charger, well built and smart in design. Buttons and body are stout, and interface is well thought out. You dont need to select the cell like many chargers, controls work the last cell inserted. You can opt to put in all 4 cells and control all the same making charging setup quick. And yes, you can charge or discharge, test all together at different voltages by setting each cell then moving to the next. Tested actual battery mah to 2 other chargers on 3 separate cells and it's very accurate to other readings. Heat sensor protection makes it safe to operate (haven't gone over 105F yet @ .7 amps). All in all this is a perfect charger for those that want all the info you could use to determine your cells are working well. Easy to use and looks built to last, much more so then any competitive priced chargers I've come across. 2/7/13 Update. After buying a 2nd unit and running extensive testing along with some other users I've found some limitations that were unexpected. It seems at times it may false peak running full power 1.0amp x 4 cells. 2 other users reported this and it happened to me as well after many test runs. I've never had any issues running 4x .7amp charges and it's been 100% reliable at that setting (AA). So if your not set on running 4 cells at 1 amp and 3 hour or less charges are fine, it's still a very good charger for those condition. Recommend .7amps for AA and .5amps for AAA. Stick with those settings and you should be good to go. Also, 1.0 and 1.5 amp charges should be fine for 2 cell charges in slots 1 and 4.

This seems like a great charger, it has lots of options and does charge each bay individually. This also provides information about the status of each battery, voltage, milliamps, and milliamp hours. It allows you to charge, deplete and recharge to condition the battery, and to analyze the battery. The part I was mistaken about was the analyzing of the batteries. I figured I'd put one in there and get a reading of the MA/MAH. Turns out though, to get this you have to allow the charger to "do its thing" which is I think a condition cycle and then a re-charge. Doing all of this takes a long time. So finding out the status of a battery isn't that easy or quick. The charging part is handy, you can charge at different rates - 200, 500, 750, 1000ma rates - a great feature if you want to slow charge a battery vs. doing it quickly. So the features of this are amazing and at an amazing price. This isn't a simple fast or slow charger and that is all - it is way more. But sadly I really wanted to know easily and quickly if some of the older nimh batteries I had were worth keeping or recycling - and this isn't quick or easy to find this out. I'm sure it is worth the money, especially since you can drain and re-charge (condition) a battery and maybe give it new life instead of assuming it is ready for the recycle bin. UPDATE: I have spent some time working with this charger. It can be a simple plug and charge unit, but it is worth going beyond that. You can change the charging amperage going from a slow charge to a fast charge, and everywhere in between. Fast charging is super fast. You can re-energize older batteries by using the conditioning mode. Activating features and understanding the many display options are a challenge - I'm a tech guy and I struggled to understand it all. But I did and have found this to be a great unit. The end of whatever cycle you use (there are 4 modes) it is possible to see the MAH rating of the battery so you can decide to keep or recycle based on how well it rates (press display even when it displays the word FULL until you see MAH). Just note that the MAH will change from MAH to AH automatically when it exceeds 1000mah, which is typical on AA nimh batteries. I would HIGHLY recommend this if you are inclined to take the time to learn the charger and allow the batteries to go through a process of conditioning - which can take a day to drain and recharge (or whatever else it does) to condition these batteries. You won't waste getting rid of older batteries that are still okay or new batteries that aren't up to par.
