Hearing aid batteries

A standard hearing aid battery lasts anywhere from 3 to 22 days, depending on the hearing aid type, battery type and capacity, and the amount of hearing aid use.

• 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.

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.

• 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.

• 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.
