It seems like the premum from Energizer are better than the Duracells
I switched from Duracells to the Energizer Lithium Ultimate (there is , lower, another "rank" of energizer Lithiums there, be sure ot look for "Ultimate" only)
Advertised as holding power for 15 years.
Duracell Lithium advertise 9 or 10 years.
Made in USA BTW....
