[8x AA] I love these rechargeable eneloop batteries so much, that I have purchased these batteries for all of my flash units. These batteries are powerful and they last a long time during my photo shoots to the point where I have never had to change them. The only regret I have about eneloop rechargeable batteries is that I should have purchased them years ago. Since buying and using these batteries (which is about 6 months now), I have never gone back to purchasing or using Duracell AA batteries and I never will go back using them for my flash equipment.

[8x AA] Eneloops are the best rechargeable batteries you can get , so good that people counterfeit them. B&H is one of the few places where you currently don't have to worry about getting fakes.

[8x AA] I have been getting great performance from the ENELOOP batteries. This was a re-order because I'm using these wherever I use AA-AAA batteries.

[1.2 V] I've been using Eneloops since they came out. I have ~120 AA and AAA cells in various types of equipment from TV remote controls to DVMS, to HTs, to speedlights. My battery analyzer shows that some dated 2010 (2nd Gen), and used daily, have lost less than 10% in capacity. And none have given me any problems; no failures, no leakage.

[1.2 V] I was looking for easy to use rechargeable batteries. BH is a huge place and the first sales assistant showed me right away where to go to get what I needed.

[8x AA] I've used these all over since they first came out and have never had one be defective or die prematurely. Very reliable.

[0.475 lb] I've been using eneloop batteries since 2006 and it wasn't until last year that a few of the oldest ones started dying. I used keep a few spare alkaline batteries around as backups, only to have them self-corrode on the shelf long before their expiration date. I don't bother with that anymore since the eneloops maintain charge in storage well enough that they are more reliable than alkaline even for emergency backups.

[8x AA] Used them for a Wedding the next day.

[0.475 lb] Over the years the eneloop rechargeable batteries have proven to be the most reliable. They hold their charge really well. I can leave them in my older Nikon speedlights without worrying about leakage -- though it is still best to remove any battery from a device that is not used for years. And when I need the speedlights there is enough charge while I am charging others. The Panasonic chargers included in some SKU's are highly recommended. They provide the best current regulation for these batteries.
