A:AnswerThank you for submitting your question! The life span of the battery depends on the volume of usage of the user, and the type of the hearing aid itself. If it is a high drain device that processes high volume type of sounds, the battery is expected to deplete faster. If it is a low drain device that processes low volume type of sounds, the battery is expected to deplete at lower rate.
