Hearing aid batteries everActive PR44 (size 675) — pack of 6

Pack of six everActive PR44 (size 675) hearing aid batteries designed to supply reliable power to hearing instruments that require 675 cells. These zinc-air cells conform to standard size 675 dimensions and nominal voltage, making them compatible with most behind-the-ear (BTE) and in-the-ear (ITE) hearing aids specified for 675 batteries. The pack contains six individual batteries, each sealed with an activation tab to preserve shelf life until use.

Advantages

everActive PR44 batteries deliver consistent voltage output appropriate for devices that demand the higher capacity of size 675 cells. Zinc-air chemistry provides a stable and predictable discharge curve, which helps maintain device performance throughout the battery life. The individual seal tabs extend shelf life and simplify transport and storage. The batteries are lightweight and shaped to fit standard 675 compartments, enabling straightforward replacement.

Suitable for

• Behind-the-ear (BTE) hearing aids that specify 675 batteries
• In-the-ear (ITE) and custom-fit hearing instruments requiring size 675
• Everyday battery replacement for non-rechargeable hearing aids
• Devices and situations needing extended runtime from a larger zinc-air cell

Key specifications

• Cell type: zinc-air
• Size designation: 675 (PR44)
• Quantity: 6 batteries per pack
• Form factor: button cell designed for standard 675 battery compartments
• Typical use: disposable primary battery for hearing instruments

How to use

Before inserting, remove the protective adhesive tab to activate the zinc-air cell; allow the battery to ventilate for a few seconds to reach operating voltage. Insert the battery into the hearing aid following the device manufacturer’s polarity markings, ensuring the flat side matches the positive or negative orientation required. Close the battery compartment securely. Replace batteries when you notice reduced device volume or distortion, and dispose of used cells according to local battery disposal regulations.

Usage recommendations

Store unused batteries at room temperature in a dry place and avoid carrying loose cells in pockets with metal objects. Replace all batteries at the same time and remove a battery from the device if it will not be used for an extended period to prevent leakage. For optimal performance, follow the hearing aid manufacturer’s guidance on battery handling and replacement intervals.
