Good Product
I ordered 12 of these NiMH batteries for use in various AA powered devices. They all tested at over 100% of their rated capacity, when discharged at 700mAh.

This is my 2nd order from Battery Junction
This is my 2nd order of Panasonic Eneloop Pro batteries for a grand total of 48 batteries. As a photographer I need batteries that are dependable and have a decent power curve, the Eneloop Pro 2500 mAh batteries are just such a battery. Whereas the output of standard AA batteries drops significantly after initial use the Eneloop Pro batteries maintain a constant output for a significany longer period of time. As an example, when using standard alkaline batteries I get about 20 full power flashes before my recycle time goes from 4 seconds to 7 seconds. With the Eneloop Pro batteries I get about 75 full power flashes before I see a time lag between cycle times. Lets face it, 4 of these batteries cost as much as 32 AA Alkalines but the constant output and ability to recharge is woth the cost.
ProsConstant output level, 75% more than alkalines. Rechagable ( about 9 hours for full charge, depending on charger) low self discharge
Conscost rechargable up to 500 times (2000 mAh versions rechargable up to 2000x)

Very enviromentally friendly
Each battery can replace 500 alkaline batteries. Imagine the raw materials, packing, shipping, handling and production energy that saves. These are so much better than batteries that you only use once. Also since these never leak (I have never seen one leak and I have about 100) imagine the flashlights that are ruined and have to be replaced because of alkaline batteries. Ruined flashlights is waste generation. Lower internal losses because of low internal resistance. This gives greater current for photography flashes, high brightness flashlights and other high power devices. This results in more run time and faster flash recharge.
ProsEnvironmentally fantastic. Save money versus alkaline or other one use once batteries. Will handle higher power levels efficiently so less energy from the cell is wasted as heat, giving longer run time. Will not leak and ruin flashlights or other items.
ConsThese have not been widely advertised by the suppliers as to the advantages. Lower profit for battery manufacturers and sellers.

Best AA Rechargeable
I have over 12 trail cameras in service and the Enelloop Pro Black batteries have been consistently the most reliable. Better than the White premium version. Better than other higher capacity brands.
ProsBest and longest lasting out of many brands tested.
