Battery Costs
I having been buying my hearing aid batteries (312) at a big box store. I pay $8.49 for 48. I have be getting around 6 days on a battery. I did some research and read that the Duracell battery was giving the longest life of any of the batteries tested. I calculated the time I am getting with my batteries from the big box store compared to the time the tests showed for the Duracell battery. If I got the time, as calculated, for the Duracell battery they would be less expensive per hour. I was excited to put a set in and see how long they lasted. Keep in mind, I am talking same hearing aid, different battery. Turns out I get exactly the same time on the Duracell batteries that I had gotten on the other batteries. Since the time is the same, here is the calculated cost.
48 @ 8.49 = $.17 per battery 80 @ 28.95 = $.36 per battery.
Seeing that the Duracell are twice the cost of the big box battery, when these are gone I will go back to the big box.
