I have an electronic scale that uses a 9v battery and it says "use
alkaline batteries only". I prefer to use rechargeable NiMH
batteries. How can the product tell the difference (or can it) and
what would be the problem, if any, of using non-alkaline batteries
in such a product.

Thanks,

Rechargable batteries tend to have a lower voltage than
non-rechargable, so the voltage difference might cause trouble. My
guess is the "Use alkaline batteries only" is there because the
manufacturer knows the device likes to eat batteries for breakfast,
lunch, and dinner.

Or pehaps the current drain is so low that alkalines will last for
years, and rechargables will self discharge in days to weeks. For low
drain devices like clocks, calculators, and scales with LCD displays,
or other infrequently used devices, rechargables do not really make
sense. Alkalines have a shelf life of several years.

Very good point!
