My hearing aid battery runs out after 2 days. It used to last 2 weeks — why has this happened?
Hearing aid battery voltage drain may vary depending on the listening environment. Most hearing aids brought into the office with this complaint have had poor quality batteries installed. The quality of batteries has an enormous effect on the performance of the hearing instrument. Occasionally, a short or defective part in a hearing aid may be responsible for excessive battery drain. If proper quality batteries are inserted and the problem persists, please contact your hearing health care professional. Finally, some models of hearing aids especially “completely in the canal hearing aids” have been known to be significantly harder on batteries with a battery life span of only 2-3 days.
