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