Product Description
Conventional rechargeable batteries have numerous advantages that make them great to use for your portable electronics. But they also come with certain disadvantages. After purchase, rechargeable batteries have to be charged before they can be used. And once charged, rechargeable batteries lose the stored energy rather fast. The charging takes quite long and rapid chargers are expensive. Not only that, but continuous charging or frequent charge to "top off" the lost energy (without complete discharge) can destroy the battery.
All these negative attributes have one root-cause: self discharge. Self-discharge means that a charged battery slowly discharges itself without any equipment consuming any current. This is the reason for rechargeable batteries being sold in a discharged state. And this is the reason that keeping charged batteries for some time did not make any sense. When you needed them, the energy was gone. Sanyo eneloop batteries have an extremely low rate of self-discharge, which means they hold their stored energy for a very long time--charge your batteries once and put them in your kitchen drawer, and over a year from now you'll still be able to use them right away, without needing to charge them again.

Best rechargeable I found, 2010-04-22
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.
Rechargeables That Has Shelf Life Close to Alkalines, 2010-03-26
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
Fantastic little batteries!, 2010-03-22
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.
Eneloops are the way to go!, 2010-06-08
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.
Near the top of the pack, 2010-03-20
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.
