Disposable Hearing Aid Batteries

Now Mercury Free – We are excited to announce that we are now only stocking Mercury Free hearing aid batteries. This new generation of batteries is not only better for the environment, but in preliminary tests, they have been proving to last slightly longer than our previous generation. These batteries will insure that you get the maximum performance from your hearing aids. Get your new Mercury Free batteries in boxes of 60 and save $25 over the normal price.

Battery Plan – Davidson’s includes a 3-5 year supply of batteries with the private pay purchase of hearing aids. The length is dependant of the performance level package chosen. See clinic for full details.

Battery Sizes – Hearing aid batteries come in four different sizes. Below is a list of the sizes, the models that each is typically found in, and the expected battery life of each size.

  • 10 (yellow tab) lifespan of 3-5 days
    size 10 are typically found in CIC and IIC models of hearing aids
  • 312 (brown tab) lifespan of 5-7 days
    size 312 are typically found in ITC, RIC and small BTE hearing aids
  • 13 (orange tab) lifespan of 7-10 days
    size 13 are typically found in ITE and BTE hearing aids
  • 675 (blue tab) lifespan of 9-14 days
    size 675 are typically found in Power BTE hearing aids

Disposing of Batteries – We recommend that you recycle your old hearing aid batteries. We have a battery recycling collection at all of our clinics, so you can easily drop them off the next time that you come in and we will recycle them for you.

Rechargeable Batteries – We also carry replacement rechargeable batteries for Signia and Siemens hearing aids in our offices as well as the Z-Power batteries used by Widex, Starkey, ReSound, Unitron and Oticon. Further to this, we also have the new Phonak hearing aids with their built in rechargeable batteries.

Maximize Your Battery Life

Here are a few ways that will help you to maximize the life of your zinc-air hearing aid battery.

  • Store your batteries between 50-77 F (10-25 C) in a low humidity environment. (Do not store in the refrigerator)
  • Store them in the packages that they come in. If they come into contact with other batteries or metal objects, they can short out and greatly reduce their life span
  • Turn off the hearing aids at night. In most cases, this requires opening the battery door
  • Wait at least 2 minutes after taking the sticker off of the hearing aid battery before inserting it into the hearing aid
  • Do not place active batteries in a fully sealed container such as a dry aid kit as this can greatly decrease the battery life

Battery Tip – Take the sticker off of your new battery and leave it for 2-5 minutes to fully activate it before inserting it into the hearing aid. This will provide you with a longer battery life.
