Duracell 364 watch batteries?

A month or so it last depend how long you have the merchandise on

is it a heavy duty battery?

Honestly I don't think it's considered a hevy duty battery . But it's one of the better battery's on the market. Sorry I don't have a better answer for you.

Need an aaa battery that is very slightly smaller in diameter than other brands such as amazon's -- will this work?

batteries are made to industry standard sizes thus the AAA, AA, etc. if you are replacing a AAA then all the brands should fit the same . The battery cradle is made to accommodate slight factory manufacturers tolerances.

They are talking about milliampere-hours.The higher the mah,the longer your battery will last under usage.
