AA Battery Charger and Batteries

[timkbryant]

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

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
