Eneloops - the only AA batteries that I trust.
June 22, 2010
I have been using Sanyo Eneloop AA batteries for about seven months now and they are, hands down, the best AA batteries that I have ever used. They last a long time both in use and when in storage. My flashlight, a Fenix TK40, is notorious for showing the limitations of various types of AA batteries. If high quality batteries aren\'t used, even brand new ones fresh from the package, the highest \"turbo\" light output setting on the TK40 will noticeably not be much brighter than its next highest setting. With ordinary alkaline cells, the turbo mode becomes the same as the high mode, but with Eneloop batteries, the turbo mode definitely blows away all the other settings. That is still true today, about seven months after I first bought my first set of Eneloop batteries.
One of the best things about the Sanyo Eneloop batteries that isn\'t mentioned on the product packaging is that they do not leak. Alkaline batteries are notorious for leaking, even when brand new, so I do not suggest using them in any electronics that you care about. Sanyo Eneloop batteries just do not leak at all. Thus, I use them in all of my electronics that require AA batteries, including not only my high quality flashlights, but all my Nikon camera equipment (F-100 and SB-23) as well. After discovering Eneloops, I will never ever use an alkaline AA battery again.
Do yourself a favor and replace all the alkaline AA batteries in your house with Sanyo Eneloop AAs. All it takes is one alkaline battery leakage to ruin your electronics gear and thus the cost of the Eneloops is money well spent.
Yes, they are *that* good.
