This review is from: Sanyo Eneloop 8 Pack AAA NiMH Pre-Charged Rechargeable Batteries (Electronics)

I purchased both Sanyo eneloop and Tenergy AA & AAA NiMh batteries. I did a capacity test on two sets of each type of battery on BC-700 charger/tester. The results are as follows:

Tenergy AA Capacity Battery 1 = 1137 Battery 2 = 1340
Eneloop AA Capacity Battery 1 = 1884 Battery 2 = 1907

Tenergy AAA Capacity Battery 1 = 747 Battery 2 = 752
Eneloop AAA Capacity Battery 1 = 782 Battery 2 = 795

Tenergy AAA batteries actual capacity is 75% (~750/1000 rated) of rated capacity
Eneloop AAA batteries actual capacity is 99% (~790/800 rated) of rated capacity.

The Tenergy AA batteries actual capacity is only 43% (1127/2600 rated) of rated capacity
The Eneloop AA are closer at 95% (~1900/2000 rated) of rated capacity.

Conclusion, spend a few more bucks and get the good (Eneloop) batteries.

** UPDATE 3/21/10 Tested another 4 Tenergy AA batteries, Battery 1 = 1228mah, Battery 2 = 1189mah, Battery 3 = 1193mah and Battery 4 = 1204mah. I'm not sure how they can call these 2600mah batteries.

5.0 out of 5 stars Rechargeables That Has Shelf Life Close to Alkalines, March 26, 2010

The biggest drawback for Nickel Metal Hydride batteries is the shelf life. I got gadgets and toys all around the house, so I constantly charging batteries to have them ready when I need them. There will be very little juice left if you put them in the shelf unused for a couple of months. A waste of time and energy. Hence, one of the biggest advancement in battery technology is the arrival of the new low discharge Nickel Metal Hydride batteries. This is another great step in helping the environment. I have very few left of the old batteries since I started to replace all of them with low discharge batteries. Eneloops and Duracell are 2 of the best of its kind.

Pros:
-Low discharge.
-Well constructed
-Conventional size and dimension. I had other batteries that I have to use a screwdriver to remove from my camera because it is fatter than other "AA's".
-Looks so sleek and sexy designwise

Cons:
-More expensive than ordinary NiMh
-Not available at many stores
-Maxes at around 2000-2100 mAh

5.0 out of 5 stars Fantastic little batteries!, March 21, 2010

I've been using AAA Eneloops for a while (maybe a year) and have been impressed with their ability to retain a charge for long periods of time. I put some in a remote for an upstairs TV back when I first got the batteries, but we misplaced the remote and couldn't find it for many months. Finally found the remote in a toy box last week (nobody knows how it got there) and the batteries are still going strong.
