Costco 312 Battery Life Study in KS9s

Might be a good time to consider rechargeable batteries.

Amazing amount of landfill waste, and that’s only one user.

I tried RayoVac 312s with my K9s. I find I get just under 5 days of life, versus 4+ days with the Kirkland branded 312s. In both cases, I wore my aids about 15 hours a day, of which 3 hours were streaming.

I agree that batteries shouldn’t go in landfills. I bring them to a recycler. Also, they actually take up very little space. I kept them in an old prescription bottle and all the batteries used in a year barely filled the bottle past the half way point.

With similar usage that is pretty much what I averaged with the old KS-6s or the new Rextons. The replaceable batteries work better with my schedule.
