Nominal voltage of zinc chloride cell

J

John

I am in the Uk and recently bought some budget zinc chloride AAA cells.
I was surprised they has a no-load voltage of 1.65v. A different brand
has a voltage of 1.69v.

Isn't that rather high? How can the manufacturers cram such a high
potential?

I did a few checks on some AAA cells....
Budget zinc chloride1:
no load = 1.65v: after 15secs at 150mA = 1.44v

Budget zinc chloride2:
no load = 1.69v: after 15secs at 150mA = 1.45v

part-used Duracell M3 alkyline:
no load = 1.45v: after 15secs at 150mA = 1.56v

part-used Energizer NiMH rechargeable:
no load = 1.33v; after 15secs at 150mA = 1.24v


Not too sure what this shows about thos zinc chloride! Any
observations?

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

See the ANSI standard for primary cells - the 2001 version

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.

Perhaps he should measure the beam current of a 26" TV tube

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
2500ma batteries, and the universities are full of hypers.

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.
