Brown is your color and the B347PA/312 is your battery if you use any of these Beltone hearing aid models:
- BTE 66
- RIE 63 and 64 (Promise and Ally)
Battery size: 312 (7.9 X 3.6 mm). Lifespan: up to 5 days (does not include streaming; for frequent streaming, estimate lifespan at 2.5 days.)
All zinc-air batteries from Beltone are activated by oxygen and thus are factory-sealed with a sticker that must be removed before using in your hearing aids. Be sure to store at room temperature in a dry environment.
Contact your Beltone Hearing Care Professional at a location near you for more information.
