When ever i buy a new wall c'lock the seller mentioned don't use
alkaline battery
just use a nomal battery other wise it will damage the c'lock.Can any
person know why ?
Thanks !

Sounds like bunk to me. Are carbon / zinc "normal" batteries still
available?

Alkaline batteries are known for their capability to give pretty much
current in a short time. That's one of the reasons, commercials for that
kind of batteries always show moving ojects that use pretty much current. If
you require very little current during a long time, the alkaline is not the
battery of choice. Ordinary zinc-carbons have a much better price
performance ratio in that type of applications. Never heard that a alkaline
battery will harm a clock. I can't imagine how. Sounds like a fairy tale to
me.

Since the wall clock uses very little current, doesn't the run time
approach the shelf life of the cell? I thought alkalines were better
than zinc-carbon cells for shelf life. I use only alkalines for the
kids toys and flashlights and NIMH for the digicams.

Alkaline AA or AAA batteries have the same voltage as their
non-alkaline counterparts. If this is a standard clock with mechanical
moving hands and one or two AA or AAA cells, you can expect the
alkalines to last at least twice as long. If these are standard 1.5V
AA or AAA batteries, your salesperson doesn't know what they're talking
about (it wouldn't be the first time!) Maybe they were out of stock on
alkaline batteries. ;-)

Your call.

Good luck

Decades ago, when zinc-carbon were the only thing available, they
certainly had a tendency to leak. I remember ruined flashlights,
and likely other things, because the batteries actually went bad rather
than just ran out of power.

So I know I avoided them as alkalines came along, and that's been
at least a couple of decades. Maybe it was just the process used back
then, and zinc-carbon don't leak these days, but I'm not sure I'd want to
risk them in something that was more expensive than a flashlight.

They are called "Heavy duty" these days.

I have a pile of "Delancey" carbon zinc cells in my recycling bucket
and they are all starting to leak.

The carbon/ zinc is still available, By ohm law current input to the clock is
the same as alkaline battery, I think it may be too strong for the moving coil,
hence foce apply to the small gear maight be too strong.

No. Both zinc carbon and alkaline are voltage sources. About 1.5V. The
current they actually supply, depends on the load, not on the chemistry. So
the clock take what it needs, not what to source is able to give. If you
have a heavy load (motors for instance) things change. An alkaline can
provide much more current then zinc carbon and can provide that current for
a longer time.

How often do you buy a new wall clock?
Is the seller the same person?
No such problems exist.
Buy what fits in the clock.
If you buy "Dollar Store" batteries with a strange name on them maybe they
will leak, otherwise no difference.

Are you sure they are not saying "Do not use RECHARGEABLE" alkalines?
