Most people have complained about their best hearing aid batteries getting depleted quickly in the recent past. What they don’t understand is that several things bring about such a rapid drainage rate. Let’s look at a few causes of quick dying of hearing aid batteries.

Other advanced functions that can lead to faster draining of batteries include Bluetooth, tinnitus relief, and noise cancellation. You can lower the drainage rate by minimizing the functions and getting the best from your device.

Altitude Change

A shift from low altitude to high altitude means a lot to the battery drainage rate. A more drainage effect occurs when batteries are in their older days. Shifting can, for instance, when going up into a high mountain or a plane. When planning a move from one attitude level to the other, expect rapid drainage of your battery.

Improper Handling of Batteries

Manufacturers educate buyers about the best handling techniques to prolong their battery life. Experts recommend pulling the battery tab once you are ready to use your hearing aid.
