About Sanyo AA

The 4HR-3UWX 4-AA rechargeable battery pack utilizes SANYO's Double X (XX) battery Powered by eneloop which provides 2500mAh of performance for long lasting, high power capacity, extreme applications. XX battery is a perfect choice for powering high current consuming devices such as photo strobe flash lights; providing more than twice the number of flashes per recharge in less than half the time as compared to conventional alkaline batteries! Wireless keyboards, mice, game controllers, radio controlled toys and a range of household devices can all realize extended performance when powered by XX batteries.

SANYO's engineers developed the XX batteries to excel in extreme conditions where high power performance in very low temperature environments (down to -4 degrees Fahrenheit) is needed. The new XX Nickel Metal Hydride batteries retain up to 75% of their capacity even after one year of storage. Unlike regular alkaline batteries which can only be used once and are wasteful to the environment, the XX batteries can be recharged up to 500 times. They come pre-charged and can be used immediately out of the pack. XX Powered by eneloop batteries deliver reliable, high power battery performance when and where you need it most!

The only batteries I will use now

These batteries are by far the best rechargeables I have used to date. I purchased these for use in my Canon 550EX speedlight after hearing good things about the Eneloops. Right out of the package, without charging them, I was able to get a little over 400 flash cycles out of them over the span of 2 months (the final 100 were shot outside in 20 degree F weather). I have never been able to get that out of any other battery, lithium, alkaline or NIMH. I am sure these batteries will last even lo...

So Far So Good

By

from Charlotte, NC  -  Semi-Professional

These were charged out of the box and ready to use. I'm using them in my Canon 580EX II's and I've only had them out twice so far, but they seem to work just fine. Recycle time seems to be just as good if not better than regular Alkyne AA batteries.

Great alkaline replacement

By

from Washington, DC  -  Quality Oriented

At first I was skeptical that a rechargeable battery could replace the alkalines I use in my equipment, especially with manufacturers warning that rechargeable will perform so badly. However, these batteries work. My primary use for these is with my Tascam DR-40. I could easily burn through three dozen alkalines in a weekend. I've run some simple tests using my DR-40 and the rechargeables last as long or longer than the equivalent alkalines. I also recommend the Maha PowerEx MH-C801D for recharging these batteries.

Might out last me

By

from Indiana  -  Getting Started

Haven't had these that long and so I'm still breaking them in. They seem to be doing all that they should be doing.. Have placed these in some night lights in the house and then charging in the morning. If they live up to the 1500 recycles that had been said they may outlive me. I would buy them again and may do so in the future
