NiZn, and it

ger before dropping to 1.1 or 1.0 V

The NiZn cells deliver ~1,500mAh x 1.7V nominal discharge voltage =3D

2,550 mWhr. A typical low self-discharge NiMH is ~ 2,000mAhr x 1.25V =3D 2,500mWhr.

In my devices NiZn lasts a lot longer than NiMH because the switchers are so much more efficient at the higher input voltage.

So, rating in mWHr seems very fair.

become competitive it seems.

They're certainly environmentally attractive. Hopefully they'll get refined/perfected over time.

Hey, for the case where a SWITCHER is used, you are right. But Mr consumer may put it in a flashlight, and use it until it looks like a glowing nail.... Those wire type bulbs behave a bit like a current source too.

You mean fire-bottles? (Do people still have those?)

The NiZn isn't gonna work in those. 1.8v isn't good for them!

Never heard that expression, googling for it shows it can mean anything from Molotov cocktail to fire-extinguisher..

I actually have 2 flashlights with indescandent bulbs, both run on 4 duracells, in once you can select between LEDs and indescandent. The duracells have been in once of those for more than 5 years I think. The other one had a sealed lead acid rechargable that I killed by accidently leaving that light on (I think), replaced it by 4 AA.

Na, ya, bit more light :-)

do they even make an 8 port eneloop charger anymore?

here's one, not sure where it was sold or why it's not available in the US

I'd use the things if I could charge 8 at once in a charger that doesn't smell like burning chinese electronics and won't kill the batteries or burn the house down with some crazy speed charging mode.
