This review is from: Powerex AA 2700mAh Rechargeable NiMH Batteries w/holder- 4 Batteries Per Pack (Electronics)

These Powerex AA rechargeables are the best I've tried.

I've tried several different brands of NiMH AA batteries (Delkin @ 2900 mAH, Power2000 @ 2500 mAH, La Crosse @ 2600 mAH, Duracell @ 2650 mAH, and DigiCam @ 1800 mAH). I use the La Crosse BC-900U charger on all of them so that I can see to what capacity they can be charged to, and even the La Crosse batteries that came with it can't be charged up to their own stated capacity. Duracell and Delkin both had a dud in each 4-pack of AA batteries. For all five manufacturers, the fully charged capacities of their AA batteries never exceeded about 80% of their stated capacities. None ever came close to a "full charge'. There was always at least one in each pack (excluding the dud in each pack) that would only charge up to about 50-60% of capacity, which would lead to a premature "Low Battery' shutdown of my camera.

The Powerex on the other hand, all charged to 95%+ of their rated 2700 mAH capacities and really last!.

5.0 out of 5 stars The BEST rechargeable AA batteries, July 1, 2007

This review is from: Powerex AA 2700mAh Rechargeable NiMH Batteries w/holder- 4 Batteries Per Pack (Electronics)

I purchased 4 packages of these batteries to use in my electronic flashes at a wedding. One set of charges AA batteries got over 300 flashes on my Nikon SB-600. This is over double the expected number of flashes that are expected according to the Nikon owners manual. These batteries are the best NiMH batteries I have ever used (and I've been purchasing many brands over the years.) They also have an excellent shelf life which I have never seen in other brands of NiMH batteries. In short, if you need rechargeable AA batteries, just buy these. You won't be sorry.

This review is from: Powerex AA 2700mAh Rechargeable NiMH Batteries w/holder- 4 Batteries Per Pack (Electronics)

I was looking for a good rechargeable battery with at least 2000 mAh. I decided to buy eight each of the following three types of batteries:

Duracell DC1500B4N Rechargeable AA NiMH Batteries (2650 mAh)
Powerex AA 2700mAh Rechargeable NiMH Batteries (2700 mAh)
Sanyo Eneloop AA NiMH Pre-Charged Rechargeable Batteries (2000 mAh)

I'm posting this same review for all three batteries.

I also bought a La Crosse BC-9009 battery charger (which, apart from the manual, is quite excellent). This charger gives you the option to test battery capacity, so I used it on the 24 batteries that I bought. Granted, a sample space of 24 batteries is quite small, but it's good enough.

The Duracells came in at 1547, 1399, 951, 2200, 2220, 2180, 940 and 905 mAh for an average of 58% of rated capacity (avg. 1543 mAh / 2650 mAh).

The Powerex came in at 2620, 2560, 2570, 2630, 2440, 2470, 1318 and 1053 mAh for an average of 82% of rated capacity (avg. 2208 mAh / 2700 mAh).

The Sanyos came in at 1940, 1867, 1931, 1961, 1856, 734, 1786 and 1895 mAh for an average of 87% of rated capacity (avg. 1746 mAh / 2000 mAh).

Although the Sanyos 87% is better than the Powerex's 82%, the powerex comes out better from a cost perspective. The Duracell's were not even in the running.

In September 2009, for 8 batteries, the Duracells cost me $22.22, the Powerexs cost me $25.98 and the Sanyos cost $24.41.

Based on this, the Powerex's cost $1.47 per Ah. The Sanyo's were $1.74 per Ah and the Duracells were $1.80 per Ah.

Given all this, I'd say the Sanyo's were decent, the Duracell's were losers, but when I need more batteries I'll stick with the Powerexs.
