Interestingly, in my Alta2 aids Duracell lasted about half a day longer than Kirkland Signature; but in my Opn aids with their higher power demand of streaming the Kirklands actually last longer. It must be something about the power curve on the two batteries. In my Alta2’s I got about 6.5-7.5 days with KS and 7-8 with Duracell; in my Opn’s, I get 3-4 days with KS and sometimes as little as 2 with Duracell.
