Enter the total battery capacity (amp hours) and the power usage (watts) into the calculator to determine the hearing aid battery life.

Hearing Aid Battery Life Formula

The following formula is used to calculate a Hearing Aid Battery Life. 

HABL = 10 * BC / P
  • Where HABL is the Hearing Aid Battery Life (hrs)
  • BC is the battery capacity (amp hours)
  • P is the power consumption (watts)

To calculate the Hearing Aid Battery Life, multiply the batter capacity by 10, then divide by the power.

What is Hearing Aid Battery Life?

Definition:

A Hearing Aid Battery Life is the total time a hearing aid can run without being charged.

How to calculate Hearing Aid Battery Life?

Example Problem:

The following example outlines the step-by-step process for calculating a Hearing Aid Battery Life.

First, determine the battery capacity. In this example, the battery capacity is 20 amp-hours.

Next, determine the battery consumption power. In this case, the consumption rate is 10 watts.

Finally, calculate the Hearing Aid Battery Life using the formula above:

HABL = 10 * BC / P

HABL = 10* 20 /10

HABL = 20 hours

FAQ

What factors can affect the battery life of a hearing aid?

The battery life of a hearing aid can be affected by several factors including the volume at which the hearing aid is used, the type of hearing aid battery, the age of the battery, the temperature and humidity of the environment, and how often the hearing aid is turned on and off.

How can I extend the life of my hearing aid battery?

To extend the life of your hearing aid battery, you can turn off your hearing aid when not in use, store batteries at room temperature, avoid exposing your hearing aid and batteries to moisture, and use a battery tester to avoid mixing old and new batteries.

Are there different types of batteries for hearing aids?

Yes, there are several types of batteries for hearing aids, commonly known by their color-coded sizes: 10 (yellow), 312 (brown), 13 (orange), and 675 (blue). Each size offers different capacities and lifespans, tailored to the power needs of various hearing aid designs.
