Using my Lacrosee BC-700 battery charge/test function, the 4 "AAA" batteries performed as follows:
Battery 1 = 913 mAh
Battery 2 = 901 mAh
Battery 3 = 894 mAh
Battery 4 = 942 mAh
(See picture on customers' submitted images)
All packs a lot of juice compared with other comparable brands, and even slightly higher than Eneloop and Duracell.
Although, Duracell and Eneloop rate their batteries only 800mAh but perform better on tests, Imedion rates their batteries as 950mAh, but in my actual test performed lower as shown on above results.
(I will run more tests to verify whether 950mAh rating is justified)>
Imedion is from Maha Energy Corporation. They also make 9V, C and d pre-charged batteries under the label Imedion.

I use these batteries in my vibrator. Trust me, it's important that they don't run out at the "wrong" time or it could be pretty frustrating! So far I've been happy with them, and they seem to work better than the reachargeable Energizer and Duracell brands I've used before.
I use a Duracell brand battery recharger that I already own, and these batteries reacharge fine in it so you don't have to buy the "matching" charger if you already have one.

I have used several low discharge AA and AAA batteries including Sanyo Eneloop and Spectrum batteries like Rayovac Hybrid. The Sanyo Eneloop were reigning supreme until these came along. These seem to blow them out of the water. Mine arrived rather chilled from a UPS truck in Minnesota. My ZTS battery tester read them cold at 100%. These things peform well warm as well ... which is a major improvement over the others. Further, they offer a strong 2100mAh rating and I find this a bit conservative with my C9000 charger in break-in mode. At the promised 85% capacity after one year, no other low self discharge battery out there can compete. What can I say? These are MAHA Powerex batteries!

I've been using rechargeable AA batteries for quite a while in my Nikon CP990 and have been a fan of Maha brand batteries since the beginning. I upgraded as new and stronger models came out, each with the ability to last longer and longer...however up until the Imedion the increase in performance was incremental and the discharge rate over time seemed about the same.
Well those days are over, the Imedion brand is more than different by the slick re-branding and new name, it actually significantly out performs the previous Maha batteries I've used and to top it off the discharge rate is much slower. Where with the previous batteries I'd be lucky if I can spend 5 shooting days before needing to recharge; with the Imedion 2100 I can double that time! It is quite liberating not to have the camera die on me just when I want to take a shot, I recommend these to any one using a digital camera and I am sure they'd be awesome as well in remote controls and the toys of children. A great product from Maha, highest recommendation!

I can't believe how great these batteries are. I recharge them with the La Crosse battery charger I bought with them. I used to use the non-rechargeable Alkaline Ultras from the major battery companies and just saw my money thrown away after they discharged. These PowerEx's have saved me a LOT of cash in the past few months. I use both AA and AAA batteries for a fair number of electronic gadgets I have around the house, from battery operated bluetooth mice to portable radios to smaller walkman radios to portable cordless desktop lights and I am SO impressed at how LONG these batteries last. I think they actually OUTLAST those expensive Alkaline Ultra Ultras I used to use! I can't recommend these too strongly. They are THE BEST rechargeable batteries I have EVER used. Buy them and SAVE SAVE SAVE money over the long haul. They are a fantastic value!!! Oh, one more thing...you can charge them up in advance and keep a stockpile of them just as you would regular batteries. They discharge very very slowly so no worries about having them lay around too long. These ARE a BEST BUY!!

Use these batteries every day. Recharge them every time we use them professionally. they just keep on working. We shoot probably 10,000 shots (no kidding) with the batteries in a year and then buy new ones.
