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 and then divide by the power.

## What is Hearing Aid Battery Life?

Definition:

A Hearing Aid Battery Life is the total time that a hearing aid can run without needing to be charged.

## How to calculate Hearing Aid Battery Life?

Example Problem:

The following example outlines the step-by-step process to 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
