Sanyo eneloop AA batteries

LOL good point! I'm talking about eneloops. I thought Mark1 was also.

Yes the Eneloops. They are about half dead after a week. I bought a battery tested just to prove to my self I am not crazy. They are strong enough to run the flash for a few quick grabs of the kids.... But even then they recycle so slow. I finally threw then out a few weeks ago. So far I am having better luck with some cheap Rayovacs I needed in a hurry.

I use Eneloops and Rayovac Hybrids - I haven't been in a situation where the recycle time affect my shooting, but I do replace them after a month or so. There's a huge thread on battery testing somewhere here...

I have not done any head-to-head testing but, it appears that the Eneloops recharge faster than alkaline batteries.

I recharge them with the supplied slow rechager. From what I have read, the quick chargers don't work well with the Eneloop batteries.

In fact I have purchased a second charger since recharging more than one set of batteries is such a slow process.

Charge faster than alkaline? I sure hope that alkaline doesn't recharge at all

Wow, that has not been my experience. I have several sets and they often sit for weeks without use. Every time I have popped them into the flash units (430 and 580) they work like a charm.. and I don't have a complaint about recycle time, as they seem faster that any other battery that I have used. They also last much longer (more pops) than any battery I have used.

Perhaps something happened with yours ..

Eneloops for my PW's, and Powerex's for my 580exii's. I based my decision on this thread, which I'm surprised nobody's posted yet... https://photography-on-the.net …677074&highligh​t=eneloops

I think that's because the guy that made the thread was posting here. I need to get some powerex's. How much faster is the cycle rate of those compared to eneloops?

The recycle time will be almost identical. The mAh rating doesn't affect recycle time, only the number of flashes produced. You've got a bigger water bucket with the higher mAh batteries, but the drain hole at the bottom is virtually the same size.

OK so you mean powerex has MORE pops per battery but drains faster over time
and the eneloop has less pops per battery with drains slower over time

I run Eneloops in anything that requires AA or AAA batteries, including flashes. I love them and they've never failed me.

I meant that the ability to deliver current to charge the flashes' capacitor is about the same, i.e., recycle time for the flash will be similar regardless of the mAh rating.

Your statement above is accurate. Eneloop batteries won't give as many flashes but they will still be useful in a couple of months when the higher capacity batteries have lost their charge. But if you use the higher capacity in a short period of time (and charge them before each outing), the 2700 mAh batteries are a better choice.

I'll take twenty flash pictures one day and it may be a month before the flash gets used again. So in my case, eneloop batteries are better for me.

According to that guy's tests, up to first 100 pops or so both Powerex 2700 and eneloop's recycle time is about the same. Longer it goes, however, Powerex 2700 can sustain the recycle time a whole lot better than eneloop.

I just got a set of the new Eneloop XX, haven't really run them through any good tests yet.

I have several sets of regular eneloops and use them in my flashes and other things like Xbox controllers, which they are excellent in.

I have had no problems with them so far.

I moved to a 15 minute charger a while ago. Because of the eneloops that I had being so short lived. I had to.... Charging them for 4-5 hours each set.... and I have 5 flashes to feed.... I would be there for days ahead charging them all. So I went to a 15min and could do it in several hours.

I know that it is not that "good" for the bateries. But I know of some that have been used for years with no detriment to the battery either in holding the charge or duration while in use. But I also dont try to wring out every last charge that I can. One set of rechargeables pays for it self with about 3 charges. After that, it is all a bonus. So I dont mind dumping them when they cant keep up any longer.

Good point. That's where the higher capacity comes into play.
