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.Get more detail about Tenergy High capacity NiMH Rechargeable battery package: 12 AA 2600 mAh + 12 AAA 1000 mAh.
