Nominal voltage of zinc chloride cell

More data:

My observation would be someone gave you a digital voltmeter for xmas and you didn't know what else to do with it?

Sure. What happens when you put them upside down?

The polarity changes! Whouuww!

See the ANSI standard for primary cells - the 2001 version downloadable from here:-

max open circuit voltage for a Zinc Carbon/Chloride is 1.8V per cell

You can't rely on a little load at 150ma, why not try 0.5 - 1 amp? You will see a better picture, right now you see gray picture. Not a good source to make a determination. Repeat the test several times to make sure your meter is out of wax.

Good guess, I was going to say his meter is out of wax.

I would lay odds that "Jim Thompson" didn't actually write...

as he is a native English speaker, and the idiot whose best use of time seems to be to try to spoof other people clearly isn't.

Look at page 6 of this document. There is a perfectly good technical explanation for the shape of the discharge curve, but I can't tell you. We wouldn't want the terrorists to get their hands on this information, would we?

The standard costs between 68 and 75 bucks, per section. Your link is to the "scope of" summary.

Hey Rat, I won't disagree with you Rat Bastard, I love your cute name.......Heehee.......Dontchaknow?....... I can still do business with you, pls see details of my work below:

Dunno if I can trust Duracell, their 2-hr charger took 8-9 hrs to charge

So it is. Best try here then:-

This is for the 2001 version : for 2005 you must pay the bucks

Yes, you bought a Chinese voltmeter.

P.

No problem! He can use a big ole screwdriver to pry a chunk out of each ear, and he'll be all set for another couple months.

Hey, I want some of those "alkyline" cells - the voltage gets higher when you use them!

Hmmm, 8% rise over 15 seconds. That's about double the voltage every couple of minutes. By the end of the day, I'd have more volts than I'd ever use.

Be careful. If you draw too much current from them, the resulting ionization flash will melt everything in your house.

Whatsamatta poor soldier? No friend? Can't help it? too lonely? Your big problem is, you're such a dumbfuck chipmunk follower. And no God is not blessing America as you asked. Do you know why? You guys sinned against God Big time, you killed million innocents and you do not count them.

Yawn. What a patheitc forgery.
