I am a new owner of a pair of Siemens Music hearing aids.
I am looking for low cost sources of 13SA or equivalent Zinc Air
Is there a Battery of the Month club?
Do all size 13 batteries provide the same number of hours of use
or should I look for a particular manufacturer or part number for
best performance versus lowest cost?
Please post to group and email reply to me also if possible.
