All batteries are of the same quality, I think! Try resetting and downloading! By the way, it is perfectly normal for batteries to run out every month! Here is a few ways to save them:
go to any grociery store ( i go to bel air) and go to the battrey, camera, etc. aisle. Then go to the small round battreys. Then get a battrey that say CR2032 and buy it. thats what i do! hope it helps!
