I used a LaCrosse Technology BC-900 AlphaPower Battery Charger to test these batteries (for sale on Amazon.com, by the way). The BC-900 can condition batteries by repeatedly charging and discharging them until no improvement in battery capacity is measured. I applied this feature to the Power 2000 batteries. Conditioning is a necessary step prior to testing new batteries, since NiMH batteries need several charge/discharge cycles before their maximum capacity is reached.
I used the most gentle setting that the BC-900 offers: 200 mA charge, 100 mA discharge. I used another feature of the BC-900 to test the capacity of the POWER 2000 batteries after conditioning was complete. Again, I used the most gentle setting. This should result in the most optimistic estimate of battery capacity. Results? The four batteries measured:
2190 mAh
2120 mAh
2070 mAh
2140 mAh
Nowhere near 2700 mAh, eh what?
I suggest that all products from POWER 2000 be scrupulously avoided. This company is clearly dishonest.

At 2700 mAh capacity, these rechargeable batteries provide up to 50% more power than comparable rechargeable batteries delivered less than a year ago. This means that you've got more and longer lasting power per charge when running your Digital-camera or any other portable device that accepts AA rechargeable batteries. The Power 2000 high-capacity AA rechargeable nickel-metal hydride batteries works for every item that uses AA batteries such as Digital Cameras, Flashes, PDA's, CD players, MP3 players, handheld video games, portable GPS devices, and many more. It lasts a lot longer than AA batteries made of alkaline or niCd cells, which were ineffective for high-drainage and power-hungry devices.
