High energy @ a low price!

With 2500mah they last longer than most disposable batteries and with a 1,000 recharges they cost less than a penny a day to use!


Most Liked Negative Review


Sorry, I do not recommend for purchase

The battery purchased only worked well for a month in our cannon camera. Afetr that what ever way we charge, it does not get charged to work in camera. Battery gets hot while charging. The charger it self stops after a charge of one hour or so. We tried to charge making the charger off and on and continually for so many days but there is no result.

Capacity drops down after a few cycles


from NY  -  Hobbyist/Enthusiast

After a few recharges, the capacity dropped fast. One dropped all the way down to 678 mAH Tried the refresh function on the charger a few times but never got close to the 2000 mAH stated on the package. Not the Sony quality that I expected.


product is fine, buying it from Adorama

Great Deal for a quality product


from Shelton,CT  -  Quality Oriented

Its a very durable high quality battery from Sony . Which last long , really long


Excellent Experience


from Mason City, IA  -  Value Oriented

My original purchase was identified as an 8 pack. When it arrived as a 12 pack for the same price, I was pleasantly surprised. Excellent service from Adorama, as usual. I haven't used the batteries yet, but I expect as a Sony product they will be fine. They don't expire until 2017.


Honest responsible retailing!


from Brooklyn, NY  -  Quality Oriented

I assume that the batteries work like batteries normally do. I purchased two 8 packs at an extremely good price which turned out to be an inadvertant price mistake. Adorama instead sent one 12 pack for what I had expected to pay for a single 8 pack, and honestly explained what had occured. You can't beat that.


Fully charged!


from Rochester, NY  -  Quality Oriented

I always like these batteries because they are durable. I used it for my 580EXII, it holds up to 300-500 pics which I am very pleased.


The Best


from Crawfordville, FL

These Are Long lasting batteries they last for like 3 months when others barly last 2 weeks


pretty good for the price


from Fremont CA  -  Photo Enthusiast

I have used this to charge and restore some 20 AA and AAA size NiMH batteries and they are all working very well (some of them have not been used since 2009) after the charge. With the price I paid I am very satisfy with its performance.


Very good battery


from Fremont, CA  -  Semi-Professional

I mostly use Sony AA NiMH for my Canon flash. It never fails me. Great product.


Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
GARY C  It is a good price for the capacity, and number of expected hours of use.
Shopper  how many shots backup it has?
PHU C  I used this majorily for my canon flash. Reboot time is sufficient enough. I honestly dont go by shots because it also depends on how intensive the situations that might require you fire more often in a short period of time. Also, the batt holds its juice quite good being stored unused for a while (several weeks). Overall, this serves its purpose nicely. Of you plan to use for point n shoot cameras, such as canon power shot models, shiuld not be a problem! I also would recommend you to use it with charger that has refresh function, which can helps the batt maximize its cycles. Also, for the right price, get for pairs for back up.
Shopper  CAN YOU GIVE ME SOME TIPS ON KEEPING THE Sony Cycle Energy AA Nickel Metal Hydride (NiMH), 2500 mAh Rechargeable Batteries - 4 PackMfr. Part: NHAAB4EN SKU: BYSONMAA4 CHARGED?
GARY C  I do not suggest using them for a digital camera since they don't seem to last long for that use. I'm not sure if any rechargeable battery works well in a digital camera. They seem to work great for Phillips cordless phones, TV remotes, and most other uses.
