personally I have had great luck with SOME energizer battery's and NOT so great luck, after some digging I found out some of the battery's I BOUGHT off E bay were counterfeit branded battery's
so, heads up, that MIGHT be your issue
I used to be able to get battery's from work , there industrial line lithium energizer and they lasted better than anything I had tried
I ALSO bought some of them off Ebay and same deal, ended up NOT being REAL Energizer battery's and like you they didn;t last but a few days and died?
I am now using Duracell's LOL
and they get me pretty good life
but its a shame so many scammers are out there selling things under false advertising!
