I don't know if this is the best newsgroup for the question, but....
those little button batteries, for watches, etc... I always thought
they were 3 volts, but idle curiosity yesterday made me measure a few
and they were closer to 1.5.... of course, the package won't tell you.
Any **hard data**?

there are many different sizes and voltages.

You cannot possibly be serious.

Yes, your brain is made of concrete.

In my experience, the package often does tell you if you look.

But if you can't find it, the battery has some sort of type number,
which you can look up in a battery data book, which will tell you the
the chemistry, voltage and capacity ratings, and just about anything
else you might want to know.

As a general rule, cells that are very thin for their diameter, rather
like coins, are usually some sort of lithium chemistry and the voltage
is about 3 V.

Smaller diameter but thicker cells are often either silver oxide or
alkaline, both with about 1.5 V when new. In fact, for many standard
sizes, you can get both chemistries (e.g. LR44 is alkaline, SR44 is
silver oxide). Silver oxide is more expensive but has higher capacity
and more stable voltage during its life.

Cells that have an air hole, and a small piece of tape covering the
hole, are zinc-air cells. There used to be 1.35 V mercury batteries,
which provided very stable voltage, but these have mostly vanished now.

Then what's an AG13? ;-)

(AG is the symbol for silver,but AFAIK,they are alkaline cells.)

and more stable voltage during its life.

All the lithium cells I've seen have had the voltage marked on them;3V.
If only to prevent them from being used in 1.5v applications.

Many of them do in fact have the voltage inscribed on them though it is
difficult to see. And often it is on the packaging. It would be easy to
find a source of voltage specs on the web.

Ah; the lithium vs. silver oxide facts are useful. Thanks. I assumed
that the silver oxide was also 3 volts.
I remember mercury cells; used to seek them out for powering my cute
little radio shack/allied/lafayette multimeters.

Don't you read the packages, or take a close look at the batteries
themselves?

Gosh no, look at the packages and the batteries to see if they had
voltages on them, I never would have thought of that. (^_^)

Then, why did you say "of course, the package won't tell you"?
