I've been using various Powerex batteries to run my power-hogging Minolta Dimage 7Hi since 2002, and in that time have occasionally tried some other rechargables... not a single other rechargeable has come close to delivering the output of the Powerex's.

My most recent purchase was two 4-battery sets of the 2700 mAH versions, and they have been just superb.
Not many people know that it is recommended to recharge your batteries every month to keep up their capacity and if this is not done the performance can degrade.

Even excellent rechargeables wear out, but you can expect a couple of years of great results from these, highly recommended for high-demand digital cameras.

In this time, my original Maha MH-C204F charger has provided faithful service and is still working fine. If I were getting into the rechargable game now I'd go for the MH-C9000 WizardOne Charger, because it treats each cell individually instead of in pairs.

Glad to see Amazon is finally offering Powerex.

I am a wedding and portrait photographer, so I am always on the lookout for long-lasting, quick recycling rechargeable batteries. I have tried Lenmar, Wewin, Calumet and Energizer batteries for my strobes and the Powerex have outperformed them all. In particular, when charged in a Maha charger, these puppies will last! You can't go wrong with Powerex.

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.

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!.

I own the 2200 and 2300 series batteries and love love LOVE them! They are inexpensive and last seemingly forever.

Last year I helped document a project my classroom was doing for Very Special Arts. I charged up batteries and brought a spare set for just in case. I took over 1000 pictures and filled up my memory card before I ran out of juice in the first set of batteries. The other camera used to document this project ended up being the secondary camera because they kept having to stop to recharge the battery.

Because of how reliable these batteries have been I have started basing electronic purchases on if they take AA or AAA batteries or not. I have saved a lot of money because I don't have to buy spare stock batteries. I have 18 Powerex batteries that I use over and over for the past 2 years and haven't had any problems with them.

The charger is simple to work and holds the batteries to charge better than other rechargers I have owned. There is a feature to discharge the batteries should you need to do so.

I can't begin to imagine how much I would have spent on regular batteries had I not gotten these.
