Equipment Review – Rechargable Batteries Sanyo Eneloop

By Pye Jirsa on February 12th 2009

eneloopAs wedding photographers we absolutely destroy our batteries. It is typical for us to go through 12 AA batteries each on a single shoot. Now, shooting as often as we do, this gets quite expensive quite quickly. So, we began the trek of looking for good rechargeable batteries that could easily power flashes on their own.

We tried out three different brands of rechargeable including Energizers, Duracells and Sanyo Eneloops. We quickly noticed that early off in the trial, the Duracell and Energizer rechargeables held significiantly more charge than the Eneloops. Both the Energizer and Duracell rechargeables held charges around 2,500mAH while the Sanyo Eneleoop was at a humble 2,000 mAH.

What did this mean? Well it meant that for the first month or so the Duracell and Energizer batteries held more charge and thus lasted longer than the Eneloops. However, this quickly started to change. We started noticing that the charge and battery life on the Duracell and Energizer batteries began to diminish far quicker than that of the Eneloops.

Charge after charge, the Eneloops held up to powering around 300-400 flashes (with decent recycle times) while the Duracell and Energizers were starting to die off at around only 200 flashes.

So, if you are looking for rechargeables to be used in high power devices such as flashes, consider a set of Sayno Eneloop Batteries. You and your pocket book will be glad you did. For even quicker and more consistent flash recycling, check out our article on the Quantum C Power Pack.

    People used to ask me about these batteries all the time when I worked at an electronics shop. Caused me to look into them – glad I did. Now there are many imitators, but everyone knows the Eneloop name for low-discharge NiMH.

    I use the Eneloop batteries and agree they are the way to go! I can validate the 300-400 flashes with a SB-900 flash. Others change their batteries in their flashes much sooner than I do.

    My only concern with the Eneloop batteries is the rumor they take longer to recharge for the next shot. The SB-900 has a overheat monitor and others claim the Eneloops cause it to overheat faster than regular AA batteries. I am not sure if this is true or not since I have only shot with the Eneloop batteries in the flash.

    Others, do you have this problem?

    wow, good to know! I use a slightly higher capacity battery (2700mAh) by powerex. they sell on amazon, but I’ve found ’em on ebay for slightly cheaper. these have worked well for me, but I think I’d like to try a set of the eneloops some day. sounds like they’re workin’ well, and ppl on amazon seem to really like ’em! I’ll also soft charge all the time, which takes longer, but the trade-off is the batteries will last longer.
