They don't last longer. They last shorter, regular nimh can have higher capacity, the only upside to enloop is they self discharge slower.

They sell like crazy every time we(ncix) have them on sale. Never used them myself. Don't think they last any longer than regular AAs under heavy use, just that they discharge very very slowly if not used. Could be wrong anyone want to correct me?

When you say reg AAs you mean regular NiMH correct? If you are referring to alkaline AAs are regular AAs, these eneloops will run circles around alkaline batteries in heavy-demand devices.

Yes, if the regular NiMH had a great capacity than enelopps 2000mA hours then it would last longer (take more pictures in my case), if the batteries were both discharged at the same time, or a least within a week.

With me, I would never shoot enough pics to discharge a set of batteries in one day so when I was done and put my camera down for 3 or 4 weeks then my regular 2500 to 2600 mA hour batteries would be near dead after a month. But with these eneloops, even if I shot enough pics to reduce the capacity to 1/2 charge, I would still have more juice left after a month with eneloops then I would with the regular NiMH batteries.

Basically, I had to recharge all my NiMH once a month to keep them fully charged. With the eneloops, I can go 6 months to a year and never have to touch them. Just grab my camera with the 2 sets of eneloops and I am good to go anytime.

So if I were to use the batteries everyday in a flashlight, I would be better off with regular rechargeables that have a higher capacity? If I were to buy some regular rechargeables, what would be the better brand?

How do these precharged batteries do in cold weather vs. regular alkalines or regular rechargeables? I am talking below freezing in the middle of winter.

EDIT: It looks like Energizer has precharged batteries as well. They also have a higher capacity than eneloops.

planning to pick a few up to use in my logitech harmony remote, and my wii controllers. those thing eats batteries like crazy.

maybe

whether they are actually higher, who knows, are there any review lineups on candlepower forum or another site?

i know alkalines are lousy in cold, that is why folks have to pay for those lithium expensive batteries if they go into extreme environments.

if you do need it everyday, yes then low selfdischarge doesn't have much meaning for you, especially if you keep a second set on charge.

So, it's physically impossible or unfeasible to manufacture 1.5V LiPo cells?
Correct.
It's the nature of the component chemicals/elements used. NiMH and NiCad chemistries give about 1.2V per cell. Lithium-ion and lithium polymer are around 3.6-3.7V. Lead-acid is 2V per cell, and alkaline is 1.5V.
Complaints about voltage yields would need to be addressed to the basic properties of the Universe, C.O. the Big Bang singularity. ;)
