[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]In my SL and Rollei 35S I am using new old stock 675 mercury buttons for hearing aids, with a nominal output of 1.4V. 675 1.4 zinc-air buttons are easily anf cheaply available, from pharmacies (yes, cheap even there), hearing aid specialists and even from my local photo dealer. 625 zinc-air buttons are speciality products only available from good mailorder houses. Perhaps the commercially available ones are jst 675s with a jacket. Most likely the smaller 675 deliver less current and have less capacity than 625, but I am hoping that this does not affect the meter. Same with the 0.5V off.
