When I bought my new hearing aids in October, they came with three years' worth of hearing aid batteries from my wonderful audiologist . Today I stopped by to pick up some more and learned that they had switched brands. Previously I was using Rayovac Proline batteries, and what I got today are " Audigy Group " branded batteries, but I'm not sure of the manufacturer.
So far I've noticed that my hearing aids' battery life is dependent on the brand. Energizer standard 312s gave me just a couple days of life while Rayovac Prolines give me a week or so. I'm curious to see how these Audigy Group batteries do. I thought about using a paper calendar and just attaching the strips from the batteries as I put new ones in, but this brand is manufactured without those strips.
So I decided to make a Google Calendar for my batteries. I just set up a new calendar (under "My Calendars" at the left, select Create) and it became one of my half a dozen other calendars in Google. I just add a notation for the day "L (or R) - Rayovac (or Audigy Group, or Energizer, etc)" to tell me which side I switched out and what brand I replaced the battery with.
Have any of you been tracking battery life? What are your results? How do you track it?
