The iHEARHD Battery Module is specially designed to maintain reliable hearing device operation, and prevent earwax and moisture accumulation. Any attempt to install a standard hearing aid battery will likely damage the iHEARHD device and will void the warranty. The iHEARHD Battery Modules can ordered from our website or by calling toll free 1 (844) IHEAR44 (1-844-443-2744). A 1-month supply of batteries is included with your iHEARHD purchase.
