"Snuffy "Hub Cap" McKinney" wrote in message news 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.

About the comments about differences in current between battery types. My understanding is that 9V is 9V and the current is determined by the resistance in the circuit.
