How do I know when my hearing aid batteries are low?

Most modern hearing aids provide low battery warnings through beeps, voice announcements, or notifications in your hearing aid app. You may also notice reduced volume, distorted sound, or intermittent functionality. Some hearing aids have LED lights that change color when batteries are low. For rechargeable hearing aids, check the battery level in your app or on the charging case. It's good practice to establish a regular charging routine or keep spare disposable batteries to avoid unexpected power loss.
