Default Battery for Moisture Detector

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.

Default Battery for Moisture Detector

Forgot to say - this is a soil moisture detector for potted plants.

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

I'm guessing that if it leaks it is more toxic for plants than zinc-carbon
or lithium batteries.

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

I wonder if the writer of the instruction was
having a bad day. Might been meant to write
to use only alkaline battery?

Voltage/current curve not compatible?
Buy "heavy duty" zinc chloride batteries - they are a lot cheaper
anyway.

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

I did find a chart (half way down on the right)
comparing alkalines to carbon zinc. If you find
comparison between zinc chloride versus alkaline,
I'd sure like to see it.

In my own tests, alkalines of various brands outlast
carbon zinc four to one. I mixed and matched a bunch
of cells in various applications. Came out 4:1 fairly
consistently.

And what does that have to do with the SIZE of a 9 volt battery???

You're the one who has recently posted that
zinc chloride cells last longer than alkalines.

Maybe it's because alkaline batteries leak and destroy?

And carbon/zinc don't??

On this thread battery life was never mentioned. You just want to
prove how big a prick you are.

The only thing I can think of is that an alkaline battery has a much
lower internal resistance and that might cause a problem for the
electronics.


Just a guess.
