SOME will worl at 1v/cell. Others will not.

CY: I was careful to buy one flash light on C cells (four cell mag) because often the C cells are the last ones to be found in stores. Bummer about your experience.

CY: You are far too kind!

CY: Yes, both the short lights and the magnet ones take three AAA cells.

CY: The Etons are good. And also take AA cells. I did have a wind up radio that was far more junky. Ended up selling it off.

I've taken apart Duracell 6v lantern battery. The ones I've had were four D cells and a spacer and some metal conductor.

Each of the three or four lantern batt had ONE bad D cell, the other three were fine.

Energizer are supposed to be F cells, but I've never taken one apart.

Silly Micky. If the volume goes up, the AAA turns into an AA.

I guess so. Darn.

Even 5 or 10 years ago I don't think I used many batteries. It seems I need a lot more now.

I guess.

Actually I liked flashlights that use C cells because I could hold one in my mouth.

Now, I can hold the 3-AAA 9 LED light in my mouth and the question is, Do I attach that cord or not? I really don't use it, and it feels funny in my mouth, but not that funny!

Very nice of you.

Yeah, they do. They're quite good but anything cheaper, like at the dollar store, is too cheap.

LOL

I had a wind-up radio, but after I wound it, I put it on the floor and it wouldn't spin.

That's pretty good. I have to confess, I compare everything to the batteries I got at Monoprice. About 20 cents each, either size, 6 months ago. I only bought them to get to a minimum order for free shipping (a temporary offer) and I didn't realize how cheap they were. Now I don't want to pay shipping for just batteries, although come to think of it I think their shipping is moderate and it might still be worth it.

Yeah, you read the reviews and some mention prices far above what they are charging now. They might mention prices far below too but when prices are high, I'm not reading the reviews.

Good point.

I've never heard of them.

The spacer must have been pretty big.

CY: Yes, that is a good reason. For me, a strap on head light works OK for many things.

CY: I don't use the cord very often. Might want to leave it off.

CY: Yes, quite nice. Of course, you may wish to buy some alkalines when things get back to normal and you can find them.

CY: I tried one from Dollar Tree. The tube is too small, won't take some batteries. The batteries just don't fit in the tube. The HF free with coupon and $4.99 purchase light is good. I put grease on the tail cap threads, the machining is really rough. But, it is machined not stamped. The black HF free lights are really good light output.

CY: Some are junk. The Etons are actually reasonable quality for the size and price.

Please consider buying a wind up turntable atachment.

I remember it being kind of X shaped, and about an inch tall. Been a few years. What I remember being irritating is to think of the various 6 volt batteries being thrown out by people, not knowing they contain three good D cells. Just rip em open with diags. What a waste of perfectly good batteries.

I'll reword it:

Prices on Amazon are inconsistent.

Switch to Eneloop AAA batteries. They cost more up front, but in the long run you'll save a lot of money (and avoid throwing away so many batteries).

You can buy the Panasonic BK-4MCCA8BA Eneloop 8-pack on Amazon for about $16. That works out to about $2 per battery.

The package claims you can recharge them up to 2100 times. I have a hard time believing that figure, but even if you recharge them just 100 times, that brings the per battery cost down to just 2 cents per battery.

Yes, you'll need to buy the additional charger, but that's a small investment for long term savings.

I've been using the Eneloops for a few years now. Unlike the old Nimh or Nicad rechargeables, I can charge these up ahead of time and have batteries ready to use when I need them. I have about a dozen AA and a dozen AAA, with about half of those in various devices around the house (remote controls, clocks, etc.).

I wish they made C and D cell eneloops (not just those little plastic adapter tubes) for longer life in lanterns and whatnot, but I have very few devices that use those battery sizes anymore. It would also be nice if they made 9V eneloops for smoke detectors.

Per HerHusband:

How is shelf life?

e.g. Would you be comfortable putting them in a flashlight that would not be used for a year or so and then be expected to have a reasonable burn time when used?

Amazon page says "Maintain up to 70% of their charge after 10 years (when not it use)"

I'll let you verify that claim for us. ;-)

In general, NiMH cells (i.e., Eneloop) have a higher self-discharge rate than, for example, alkalines.

However, the Eneloops have been optimized for low self-discharge. Their open-circuit voltage quickly falls but remains relatively flat. Total capacity after ~6 months "on the shelf" falls by ~20%.

If you wanted it to be usable a year (or five) down the road, go for good alkalines. Note that the NiMH chemistry yields a 1.2V cell voltage whereas the Alkalines will be 1.5V. (This is more pronounced when the NiMH's sit unused vs. "right off the charger") So, a two-cell flashlight is already half a volt "low" with NiMH's.

[Note that you also need a flashlight with a mechanical power switch so the "switch" isn't stealing power waiting for you to use it]

I keep "crank lights" in my BoB as its not the sort of thing I remember to check up on regularly (and I *need* the lights to work, there).

However, even the crank lights rely on (rechargeable) batteries internally. So, I've been planning on modifying one of my "wind up" (different from "crank") radios to act as a power source for the flashlights (though bulky).

Also, trying to find a convenient way to package a larger "generator" for bigger loads (~10-20W)

Even if the total internal resistance of one cell was too high, would not the other 3 cells be almost depleted as well? Presumably their charge capacity was similar due to all 4 being similar in the masses of the electrodes, and during the lifetime of the 4 in series, the total current would be identical for each cell.
