Hearing Aid Battery FAQ
How long do hearing aid batteries typically last?
A standard hearing aid battery lasts anywhere from 3 to 14 days, depending on the hearing aid type, battery type and capacity, and the amount of hearing aid use.
How do I know if I should change batteries?
- Change your batteries if sounds become distorted or you have to turn up the volume more than usual.
- Some hearing aids will also make a small beeping sound when the battery is low. Be sure to switch batteries immediately when you hear the alarm.
- Hearing aid batteries often lose power very suddenly, so it’s smart to carry an extra set of batteries with you at all times.
- To protect against discharging your backup batteries, keep them away from coins, keys or other metal objects.
What’s with the seal on hearing aid batteries?
Always purchase unopened battery packages. Make sure the seal on a new battery is unbroken. A hearing aid battery begins to discharge as soon as the protective seal has been removed.
Are there ways to minimize battery drain?
- After removing the tab from the battery, let the battery sit for 3-5 minutes before installing it in your hearing aid. This “activation” time allows air to reach the materials inside the battery and activate them.
- When you’re not wearing your hearing aid, turn it off or open the battery door to minimize battery drain.
- If you won’t be using the hearing aid for an extended period of time, remove the battery entirely.
- Avoid storing in extreme temperatures to keep from draining battery power and shortening battery life.
What are some good hearing aid battery care tips?
- Store hearing aid batteries at normal room temperatures.
- Do not refrigerate.
- Wash your hands thoroughly before changing batteries. Grease and dirt on the batteries may damage the hearing aid.
- Leave the battery compartment of your hearing device open at night so moisture can escape. Doing so will keep the battery from corroding and damaging the hearing aid.
- Remove dead batteries immediately. A completely discharged battery may swell and become difficult to remove.
