Somewhere on the forum I've seen mention of a particular brand of rechargeable batteries which give exceptional performance? Buggered if I can now find the thread?

Anybody got any recommendations?

It depends what you want from your battery. There are two types of NiMH batteries: one type (called "Hybrid", like Eneloop) give good shelf life, but don't have quite as much power as the other type (like PowerEx).

So, if you want a battery you can leave in the camera bag for a month, use Eneloop (or any other "Hybrid" NiMH battery), if you want a battery which you charge up immediately before a day's shooting, go for PowerEx or similar.
 
eneyloops are great - get em on ebay about £7 incl post.
 
Another Sanyo Eneloop fanboy here. My camera (Pentax k100d) didn't last too long on 2800MA rechargeable batteries. Eneloops, even though they're nominally less powerful (about 2000MA) last forever! Similarly, for non-rechargeable batteries I found that Energizer Lithiums were the bees knees...
 
Hoping the OP does not mind, and to keep the information in 1 thread, which type would be best for using in a flash? Looking on 7day shop there are 800, 1000, 2000, 2100, 2500 mAh which confuses the hell out of my poor little brain!!

You're going to have to explain that one to me.....higher capacity cells not lasting as long as ones with lower capacity.
I fully appreciate how an "Eneloop" type battery can supply its power more quickly but how can it last longer :thinking:

I see they're no longer guaranteeing xmas delivery. so Amazon or eBay it is.

Simply put Susie, think of it as the size of your bird feeder....the larger it is then you'll be filling it less often (or birds with bigger appetites can nosh just as long as blue tits).

Bob, I would imagine that possibly the stated mAh rating of 2800 isn't anywhere near it. There seem to be quite a few like that.

A set of 8 Eneloops average 1980 mAh according to my analyser..

Maybe that's what the poster means :thinking:

Anyway, I swear by Eneloops for my flashgun, which only gets occasional use..

Hi Canon Bob

Yes, good point. That's what I found in real life. I scouted round the internet just now and this article http://www.stefanv.com/electronics/sanyo_eneloop.html says a couple of interesting things. One is the well-known fact that eneloops (and other similar ones) keep their charge for a long time compared to normal batteries, but that eneloops get better over time at retaining a charge. They also apparently have lower internal resistance so they can deliver the energy more effectively. My std batteries were 7dayshop 2800Ma ones but they weren't new - perhaps std ones get worse over time, but they weren't ancient and hadn't been overused.

All I know is that if I recharged the 7dayshop ones, put them in the DSLR, you would find that next week the camera had 'low battery' warnings, whereas eneloops would be ok the next month. Hope that helps.
 
Ah, that makes sense. I assumed that your reference to lasting longer meant more shots rather than holding their charge for an longer period.

Thanks for clearing that up.

yes indeed cowasaki you did, hi there ;)

i have noticed a lot of eneloop copy / clone batteries around now, seems all the big boys are doing an "instant" type now.

Nice info on your original post cowasaki :thumbs:

Yes there are a few alternatives. I find that I get 500 flashes out of a set of eneloops and I don't have to worry if the sets in my camera bag are going to be flat or not.
