Style Name: 4 AA NiMH
This package (Energizer Smart Rechargeable Charger for AA/AAA Batteries, with 4 AA Batteries Included) contains a very impressive-looking charger. The charger (CHP41US) features a countdown timer, a battery 'Fuel Gauge', and four bad-battery indicators. It looks like a very smart charger - until I examined closer.

The first warning sign is that: Would You Believe this charger can only charge in pairs? That is, it cannot handle 1 or 3 cells. A real smart charger has to monitor and charge cells individually, because this is the only way to ensure that each cell is not over-charged or under-charged.

The next thing I found out is that: the so-called 'countdown timer' is mostly for show. It's The Old "2-bit counter in a 7-segment display" Trick. The display always start from '8' (eight hours) when a pair of depleted cells is inserted, regardless of the actual remaining charge time. As the batteries are being charged up, the counter simply decrements through '6', '4', '2' and finally '0', even though the actual charge time may turn out to be just five hours.

The 'Fuel Gauge' on this charger is marginally useful. It shows 1-4 bars, based on the combined voltage of one battery pair. If two pairs of batteries were inserted, the fuel gauge is for the pair with the lower voltage. It soon dawned upon me that both 'countdown timer' and 'fuel gauge' are based on the same information. For examples:
2.2V = 1 bar = 8 hours,
2.4V = 2 bars = 6 hours, and so on.
By the time the combined voltage of two cells reaches 3.0V approximately, the charging is terminated. If the two cells have different capacities, then the lesser one is inevitably over-charged.

I had the same problem as a previous reviewer. This charger indicates all batteries are bad, including the batteries that came with it. I bought it new and locally for $9.99, which is what the batteries alone would have cost me, so it wasn't worth returing. Hopefully it actually charges the batteries and it's just a screwed up indicator. Still, it should do what it's ADVERTISED to do.

Style Name: 4 AA NiMH
I was skeptical of buying rechargeable batteries because some are duds. However, I bought my oldest boy an Xbox 360 and I did not want to continuously pay money for batteries. Therefore, I decided to buy this charger. It works great. The game is played a ton. Still, the batteries last about three weeks, prior to needing re-charging. Initially, you will have to charge the batteries for eight hours for a full charge. The countdown timer indicates how much time is left for a full charge. Once the counter reaches 0, the batteries are fully charged. Since the charging duration is long, I would suggest keeping two batteries charged, at all times. Therefore, when the other two batteries run out, they can be switched with two charged batteries. I don't know what the issue is with other reviewers of this product. All I can say is I got my money's worth. Not to mention, I am saving money by not continuously paying money for batteries. That can be very expensive.

I had this charger for a year. No complains about it.
You should know that the "timer" that is has, is just a timer that detects batteries and put the quantity of hours depending on that. Not really "intelligent" nor related to the battery capacity. It's helpful but not really "clever".
I used this charger for a year, and then it stopped working. Now, when you plug it, you see for a few seconds the display and it goes off and it doesn't work anymore. That happens every single time you plug it.

Style Name: 4 AA NiMH
I read a lot of bad reviews for this charger but I'm one to not really care how long it takes to charge a battery, and even if the battery charger isn't as accurate as it says it is, I still find it highly useful because I just let the batteries charge. I'm not really concerned with the "useful-ness" of the display, in fact, I use it as a night-lite for my grandson. The best part is, it does what it's supposed to, and that's recharge batteries. It took about 4 hours to fully charge all 4 of my AA batteries that had been completely expelled their use. Now I'm not saying that's a good thing (it's not 2 hours) but it's not a bad thing either. I recommended this to everyone I know and they too have had no issues. If you're an old man like me, just buy one. I don't have all day to sit around and watch the batteries charge, just leave them on overnight and they're charged by morning. Great product.

This is a great little charger for AA/AAA batteries. I use it primarily for keeping batteries charged for the Wii and a few R/C toys, it charges fast enough for my needs and is compact and seems very durable.

Style Name: 4 AA NiMH
every single battery that goes in this charger says it's bad. Brand new energizer rechargables that came with.. brand new energizer rechargables bought afterward... duracel rechargables that were bought about a year ago... none are tested to be "good". I've put these so-called bad batteries in other chargers and it charges up with no problem and holds a charge for an expected life.

at this point, i want a refund (but will be more heck than it's worth to get my $15 back).
