Pros and Cons of Rechargeable Hearing Aids in Tampa Bay – Part 2 Battery Technology

In Part 1 of of my overview of rechargeable hearing aids we talked about the pros and cons of the technology. In this Part 2, I will be delving in to the different types of batteries, both disposable and rechargeable.

Zinc-Air Batteries:

  • The most common hearing aid battery
  • Disposable
  • Four sizes: 10, 312, 13, 675
  • Last anywhere from 4 – 14 days, depending on the battery size
  • Readily available in audiologist’s office, drug stores, grocery stores, and online

Silver-Zinc Batteries:

  • Rechargeable
  • Requires replacement approximately once per year
  • Often interchangeable with disposable batteries
  • Recyclable and non-flammable


  • Rechargeable
  • 3 – 5 year lifespan
  • Fully encased in hearing aid (no need to replace)
  • Energy efficient and longer battery life
  • Fast charging mode
