Summary: BUT WHERE'S THE #523 - 4.5 VOLT ENERGIZER?
Review: I love energizer and I'm sure the Energizer ACP5136-D 4.5 Volt Cellular Alklaline Refillable Pack is up to the same great standards as usual but can you help me.....

I purchased a microphone 10+ years ago and have faithfully used the energizer No. 523 which is a 4.5 Alkaline battery. I must have purchased the "last 6 pkgs" last year because I can't find them anywhere. The nearest large city centre to where I live is Edmonton. Can you "pretty please" advise if there is an outlet/business that sells this battery or an alternate battery # I can use for my mic.
