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.
