Below, find 3 important things you need to know about hearing aid batteries for your hearing aids:
- Hearing aid batteries are zinc-air batteries and mercury free. Therefore, to get the best performance from a zinc-air battery, the factory-sealed sticker should be peeled off the back and the hearing aid battery should be left open to the air for at least one minute to fully activate before placing it in the hearing aid. Once the factory-sealed sticker has been removed, the battery is "activated" and is continuously running.
- Hearing aid batteries can generally last anywhere from 5-7 days. Of course, this is all dependent on a 16 hour per day use cycle, the size of the battery and power needed by the hearing aid.
- There are five sizes of hearing aid batteries with packaging color coded so you can easily remember what “color” battery your hearing aid requires. Size 5 is red, size 10 is yellow, size 13 is orange, size 312 is brown (also the most popular size) and size 675 is blue.
