Hearing Aid Batteries
Hearing aids require batteries to operate. Your audiologist will tell you the size that your hearing aid requires. Each hearing aid battery size is associated with a color, making the batteries easier to identify when purchasing. See the table below for the size, associated color, and the life expectancy of each battery. The life expectancy can depend on the size of the hearing aid and the amount of use. Batteries can be purchased at a store that has a pharmacy, or from an online merchant. Always buy unopened batteries (with the seal on). It is best to purchase batteries with 1.45 volts, rather than 1.4 volts. This will ensure you do not get a false “low battery warning” from your hearing aid. Some hearing aids have a rechargeable battery option.
Hearing Aid Battery Use:
- Your audiologist will show you how to insert and remove batteries from your hearing aids.
- Batteries have a positive (flat) and negative (lip) side. They will only fit into the hearing aid one way.
- Wait approximately 60 seconds after removing the peel-off tab from the battery to allow the air to activate the batteries before inserting them into the hearing aid. Read the back of the battery pack for instructions.
- Locate the battery compartment on the hearing aid and open the door. Insert the battery and close the battery door, this will turn the hearing aid on.
- Newer hearing aids will often give an audible alert to signal to you that the batteries are low. You might also notice poorer sound quality with lower batteries.
- Remove dead batteries from your hearing aid right away, and open the battery door at night or when you’re not using the hearing aids to prevent corrosion.
- Store hearing aid batteries at a normal room temperature.
- Batteries are dangerous if ingested. This is particularly concerning for small children and pets. If a battery is accidently ingested, call the Poison Control Center immediately at 1-800-222-1222.
