Huh? CREE make LEDS.
CY: Well, maybe they use different names.


Yes, Carbon zinc cells are very easy
to find in stores in the USA. Very low energy
capacity. Low amp delivery. And they lose power
rapidly. And leak easily. Brown corrosion, around
the flat negative end.

So why does anyone buy them? You'd only be fooled once.
CY: Price. The carbon zinc AA cells are eight for a buck,
at Dollar Tree. Alkalines are four for a buck. Some consumers
don't know that alkalines last four times as long. As such,
a much better product for the money.


When I was a kid (before alkalines were invented),
my Dad bought a charger that was supposed to recharge
carbon zinc cells. The second charge didn't last very
long, either.

I'm prefectly willing to use up such a cell,
for testing.

10 years ago I was looking at chargers for zinc carbon/chloride and
alkaline. They only charged them 10 times and the charged cycles were
much lower capacity than the original.
I think all the charger does is do it slowly.
CY: In the US, Rayovac used to sell alkalines
called "Renewal" which were supposed to be
rechargable up to 25 times. I did buy some,
but not used them for much.
