Trying to decide what brand of hearing aid batteries to buy, wife has
heard Eveready are not too good, RayoVac may be better. I'm curious
if any actual data out there. Consumer Reports has nothing that I
could find.



I have not noticed any real difference from brand to brand, with all of
them lasting roughly the same length of time for the same hearing aid at
the same settings..

I've been wearing hearing aids for 47 years. Battery sizes used have been
675, 13, and (briefly) 312. Currently I'm wearing a pair of Siemens Nitro,
which use 675.

What is far more important for battery life than brand is how much power
the hearing aid draws versus the size of the battery used. But that's a
design issue and is affected by the settings of the hearing aid.

Your hearing aid provider should give you a trial period of a couple of
weeks. Battery life will be revealed during that trial period.

The worst instance for me was a pair of Widex I-forget-whats I recently
tried that took 312s. My hearing-loss meant that the Widexes needed to be
boosted to nearly their maximum output. Battery life was FIVE DAYS. The
312s were simply too small for the power needed.

My surrent Siemens get about three weeks out of their 675s -- regardless of
brand. That's the longest of any hearing aid I've ever had.
