Sony ECM-50 info?
 

Hi,

I've got an old, but functional Sony ECM-50 lavalier mic. I just put a new "N" cell in, and was wondering if anybody had any info on how long the battery is expected to last in this mic? Obviously, I haven't got the manual, and of course Sony has no info...

Thanks!

mine go for months...

Thanks. I kind of figured that. I was thinking of my retired AT825, which claimed 400 hours (or about a month) of use on one cell.
