BATTERY LIFE - HEARING AID BATTERIES
How long should a battery last?
The truth is that there is no single answer that works for everyone.
Just as a hearing aid user's hearing loss is unique, battery life is also determined by different factors, so each user will have a specific battery life.
Approximately we can establish an average life span for each of the different battery sizes:
Size 675: 20 to 25 days.
Size 13: 12 to 17 days.
Size 312: 7 to 10 days.
Size 10: 5 to 8 days.
Factors Affecting Hearing Aid Battery Life
- Degree of hearing loss
As the hearing loss becomes more severe, more amplification of the hearing aids is required. This causes an increase in the energy used by the battery, so the more severe the loss, the shorter the battery life.
- Hours of daily use of hearing aids
Battery life is determined by the hours of use of the hearing instruments. The more you use the batteries, the longer they will wear out and the shorter their life will be.
- Hearing aid technology
As technology advances, hearing aid processors become more efficient, reducing battery consumption. Generally we can say that batteries last longer in modern hearing aids.
- Weather
In climates with higher humidity, battery life is reduced. It is recommended to store the hearing aids with batteries in a dry place to improve their autonomy. The use of electric dehumidifiers may also increase battery life.
- Temperature
As the temperature drops, the voltage of the battery decreases, which reduces its autonomy.
- Altitude
At higher altitudes, the percentage of oxygen in the air is reduced, decreasing the battery voltage of the hearing aid. This may cause the battery life to be reduced.
