Curious, I measured these
- Duracell alkaline AA, 86g
- Tenergy 2300 Ahr, 95g
- Amazon 2400 Ahr, 104g
- Powerex 2700 Ahr, 107g
- Duracell alkaline AA, 344g
- Tenergy 2300 Ahr, 380g
- Amazon 2400 Ahr, 416g
- Powerex 2700 Ahr, 428gg
The downside is that with all Eneloops, they are heavy and the higher the rating, the longer the recharge, and a charger must be matched to the battery — Eneloop makes its own charger, though its pricey. These batteries are used in my GPS and I can squeeze out 3 weeks of use out of that on one pair of Eneloops. I do not use them in cameras or flashes because I do not use flashes and the camera (EOS 1N with PDBE1) is heavy enough without putting in the even heavier Eneloops (x8)!
So in a flash unit (which uses 4 AA), the difference is 36g - 84g for faster recycle and more total flashes of NiMh, or 1.27 oz to 3.0 oz. Not much of a penalty.
Where can you get the 5000 mAh AA?My post referred to the larger capacity 4,500 mAh Eneloops (there are also 5,000 mAh available now, as per a friend's reminder at lunch time), not the unknown (to me) brands you mentioned, with the exception of Duracell, which I never use.
There are also Varta, Panasonic, several varieties of EverReady, Fujifilm... still other batteries.
You put x8 Eneloops in an EOS 1N's power drive booster and apart from the reliability uptick, you'll immediately notice the weight. It is a camera that is easier to wield when the added weight of batteries is a consideration. I sometimes swap out the heavy Eneloops for lithium AA, but a careful watch has to be kept on this as a power source (as a side note, specifically to the two types of power drive booster E1, only that model with the asterisk denoting AEL can take lithium AA batteries; the use of lithium AA in boosters not so marked causes shorting).
I can't be sure about making a camera go faster but the orange and black rabbits powered by Duracell here in the U.K. can certainly climb for longer than the standard white rabbit. They look more attractive as well.Unless the rechargeable would make my camera goes faster I don't want to use them in cameras.
I use MN-2 battery pack in the Nikon MD-4 motor drive and MN-30 in the Nikon F5 because they make the camera frame rate higher. That's because they put more cells in the pack than 8 cells. Otherwise, for in camera use the alkaline batteries last long enough and have long shelf life so I don't see the need to use rechargeable in them. For flash is a different story because the rechargeable not only makes the flash recycle faster but the flash uses too much power so it makes more sense to use them.I can't be sure about making a camera go faster but the orange and black rabbits powered by Duracell here in the U.K. can certainly climb for longer than the standard white rabbit.

Thanks for the factual reply, Chan Tran. My post was just a bit of fun. When I saw the phrase "make the camera faster" the amusing advert on U.K TV came into my head where the Duracell rabbit is more powerful than the normal white one. No doubt I needed to explain my post better for a non U.K. person.

All types of batteries leak. Even rechargeable ones. I had a Canon F-1 motor drive with a nicad pack and it leaked. I also had NIMH AA batteries leak too. Hopefully, engineers will design devices that take that into account and mitigate damage when leaks happen. With greater demand for denser energy batteries housed in a smaller space, some batteries explode into flames in people's pockets.I like electronic film cameras as much as the mechanical ones. One issue with electronic cameras is the need for batteries. NiMh batteries, like the older technology NiCad, still lose charge over time.
The big issue with that is a camera that gets infrequent use will not be ready to go without a charge. By the time the batteries are charged (even 15 minutes quick charge), the opportunity may be long gone.
I have converted almost everything I own to Li-Po or Li-Fe battery. Except for cameras. I'm in the process of doing that. The main benefit is the batteries stay charged. So, when I grab a camera or flash, it is ready to go.
BTW, I'm no fan of Alkaline cells. They leak and destroy equipment.

I know that some brands claim to have batteries with 2800ish mAh in them, but it's a well known fact that they lose much more juice than LSD cells from Eneloop. So it's either volatile 2800 dictated by marketing, or steady 2000.I would be surprised if anyone can pack 4500 mah in any AA sized battery. That said I use and like Eneloops.
