I've got a moisture detector that takes a 9v battery, and it says not to use an alkaline battery. Never seen that type of warning before. Anyone know why an alkaline battery is not recommended?

Thanks.

I know that different battery materials can have slightly different
voltage but nominally alkaline and carbon-zinc are the same.

They're a different size, however. iirc carbon-zinc are shorter.

You sure about that??
Lithium and other rechargeables tend to be shorter, but zinc chloride
and alkalines are generally the same.

I don't remember for sure which one is shorter but in 9v, one is.

I can't use an alkaline battery in one of my voltmeters. I have to
use a standard battery. Because it's shorter. So I guess it's the
carbon zinc that is shorter.

(If it's not shorter is more narrow, but I'm sure it's shorter.)
