Style Name: 4 AA NiMH
[Important note on June 30, 2014]
I just noticed that Amazon combined my old review for the CHP41US charger with the new Energizer CHRPROWB4 Pro Charger. I hate it when that happens! Anyway, when the price comes down I may give this charger a try (the present price of ~40USD is ridiculous for a basic charger with low-capacity batteries). In the mean time, use caution when you shop.

==== Original Review follows ====

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.

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.

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.

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).

Style Name: 4 AA NiMH
So I bought this charger because it is advertised as "smart" when it is ANYTHING BUT.

I do a lot of photography, some stills, some time lapse, so when I get home after a shoot I have two pairs of batteries with different remaining charge (lapse camera uses way more battery).

So you plug all 4 batteries into this charger, one pair on one side, the other pair on the other side... this is what happens:

They charge for 15-30 minutes, then the indicator starts flashing (error) and you go to pull the batteries out and the less-discharged batteries are HOT, VERY HOT!!

The more-discharged batteries have barely been charged!!!!

THIS MEANS: This "smart" recharger is nothing more than HYPE, and uses the SAME CHARGING VOLTAGE AND CURRENT FOR ALL 4 BATTERIES SIMULTANEOUSLY. THIS IS NOT "SMART"!

A real "smart" charger can distinguish AT LEAST between pairs of batteries, if you want to get technical, a REAL "smart" charger will monitor each battery individually to INSURE that they are charged completely and more importantly, NOT OVERCHARGED.

This "smart" charger will only charge effectively, and without DAMAGING YOUR BATTERIES, if you make sure ALL 4 BATTERIES have the EXACT SAME charge remaining when you put them in.

THAT IS NOT SMART CHARGING!!!

Do yourself a favor and STAY AWAY from this charger. You will ruin some of your rechargeables and also find yourself with quarter or half-charged batteries when you need them.

THANKS FOR THE RIPOFF ENERGIZER. I will be buying Duracell products from now on.
