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.

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

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.

Of the different brands I have, (purchased before I knew about Sanyo Enerloop) these are the ones that hold their charges the longest when not in use (perhaps in use too but I have not taken the time to measure it for sure). When I reach for Enerloop I know that I will have a fully charged, ready battery which is not the case for any other brand I own.

I charge my batteries with a La Crosse Technology charger (BC-9009) which is also the best charger I ever had and the only one I use now. (It charges, discharges, refreshes, tests and charges at different powers including trickle - also great to revive completely dead batteries). I also keep handy a small Delkin power tester (in case the charger is busy). I have not been wanting for ready batteries since I use this combination. Sometimes I think of getting a second Lacrosse charger, but really I have not had the need for it - I have maybe 30+ rechargeable AA and AAA in use at this time plus a dozen mixed spares.

Sure, eneloops may not have the high capacity of some of the other batteries, but they do hold their charge MUCH longer. I've replaced all my rechargables with eneloops, and I have yet to be disappointed.

Purchased the Sanyo 8 pack Ni-Mh AA batteries over a year ago had them in my FugiFilm camera for over 5 months with excellent results until I replaced the original 4 with the second set. The second set lasted maybe 3 weeks with little use while I had put the first ones into a Lacrosse BC-700 charger to full charge. Now both sets last about two weeks until exhausted with little or no activity with the camera. I tried to contact Sanyo with no results as of yet and Lacrosse states that their charger is working correctly and if the batteries don't hold a charge in the camera it's probably a battery fault. An expensive lesson hopefully with some type of good results. Sanyo has a 5 year warranty on the back of the package but after two months I have no answer from them....BobO

I have used eneloop AA batteries exclusively for more than three years. Long ago, I moved from disposables to rechargeables for the simple economics. Let's say you need 500 discharges from your batteries. You can buy 500 disposable batteries or you can buy one rechargeable and recharge it 499 times. You will never find the cost of the electricity you used to recharge the batteries in your monthly bill - it is measured in the single-digit pennies. So as long as your rechargeable batteries cost less than about 500x the disposables, you are coming out money ahead. When I first went to NiMH rechargeables, I found that the old-technology batteries went dead on the shelf almost as fast as when they were in use. Not so with eneloop. I can charge eneloops up, put them in my camera bag and count on them to produce full power a week or a month later. I wish all my battery needs were covered by eneloops!

I've been using the Eneloop batteries for over a year in my flash lights and electronic equipment at home, work & play.
I have found these batteries to hold their charge and out preform any other recharagesable - regardless of the cost.
This is a GREAT product!

I've been using Eneloop batteries for a few years now for my digital camera and all my "gadgets" and am very satisfied. I've yet to have one wear out or fail.

I have a PHILLIPS phone system in my house that I was really disappointed in because the batteries that came with them would die after 10 min. I really wanted to keep the phones because they look great.

I bought these batteries in hope that they would work. Put them in the phones, charged them over night then kept the phones off the cradles until they died. Believe it or not the phones lasted between 3-4 days, receiving calls and on idle. Couldn't believe it!

Performance certainly seems to be a strong point of these batteries. Highly Recommended!
