Late to the party...

Thanks everyone for your info here. I was about to make a whole new thread asking about batteries, despite having seen this one already. But just now I checked and saw this one was only created in November 2012, so there's no need to post a new one for updated information, as this is just about as recent as I can get.

Cheers.

Hi
With the eneloops does it matter if you use the 2000mAh or the 2500mAh (for speedlites)
I know 2500 is more power, and might last longer?


update
I juts checked the details on the 2500 ones, nowhere near as good as the 2000mAh ones
Low self-discharge - retain up to 75% of their capacity even after one year of storage.
The economy and environment friendliness are ensured by having 500 cycles

That's not as bad as it sounds - after 500 cycles, they don't just stop working, but the capacity deteriorates. So after 750 cycles they might be just as good as 2000mAh ones :) And do you really want to recharge them daily?

I don't think anyone I know relies on the exact amount of power after a year, it's just they don't p*ss away their power as conventional rechargeables do. You could very well use these to power a remote for multiple years, for instance, and with a flash you won't notice the difference after a month or two, which is the important point.

I wouldn't worry - I'm fully stocked up, but the minute I need more Eneloops, I'll be sure to buy a packet or two of 2500's.

very good points, thanks

Rat:
I have to come back on my promise to buy Eneloop XX's for flash use: according to this page (Dutch language), the standard Eneloops have a lower internal resistance, which means they can recharge your flash quicker. Having emptied six sets of AA's shooting indoors yesterday, I can safely say that to me, that's an important issue :)
