Energizer Mercury Free Zinc Air Battery for Hearing Aids, Energizer Hearing Aid Batteries

Energizer zinc air batteries are primarily designed to provide power to behind-the-ear, and in-the-ear miniature hearing aids. In most hearing aid applications, zinc air batteries can be directly substituted for silver oxide batteries and will typically give the longest hearing aid service of any common battery system.

All Energizer hearing aid batteries are 0% mercury batteries since 2009.

Battery Characteristics:
• Highest capacity-to-volume ratio for miniature batteries.
• Relatively flat discharge curve.
• Essentially constant internal resistance.
• Activated by removing covering (adhesive backed tab) from air access hole.
• Most effective in applications that consume battery capacity in a few weeks.
• Must have access to air (oxygen) to operate.
• Nominal voltage of 1.4
• Excellent service maintenance prior to tab removal.
• Available in common hearing aid battery sizes.
