Hello Everyone,
I made a semi-passive filter circuit that uses one 1.5 volt AA cell with a constant drain of one milli-amp. If the 1.5v AA cell remained above 1.1 volts for a year I won't bother using a on/off switch.
Will a AA last a year?
Are the Alkaline cells better in the long term than Heavy Duty AA?
Is the decay rate of a manufacturer's cells "honestly" documented some where?
Thank you,

Nope. Battery capacity for an alkaline AA is about 2850 maH
Check the url, make your own decision. Cost may come into the equation!
You mean self-discharge or shelf life figures? Probably irrelevant in any event - these small batteries are use & toss, so you keep extras on hand.

more like 3 to 6 months. with a D cell you could get a year.
yes.
the use-by date is some indication.
Bye. Jasen
