Hearing Aid Battery RAYOVAC Extra Advanced Size 10 (PR70) 1.45V Zinc-Air — pack of 8

RAYOVAC Extra Advanced Size 10 (PR70) hearing aid batteries are zinc‑air cells with a nominal voltage of 1.45 V, supplied as an eight‑pack for everyday replacement use in compatible hearing instruments. These small, high‑energy cells are made to suit behind‑the‑ear and in‑the‑ear hearing aids that accept size 10/PR70 batteries. Each cell features a pull‑tab activation and an integrity seal to preserve shelf life until first use, delivering stable voltage appropriate for low‑drain hearing devices.

Advantages

The zinc‑air chemistry provides a consistent output voltage during typical listening periods, supporting clear audio reproduction in hearing aids. The compact size and standardized dimensions ensure compatibility with most devices designed for size 10/PR70 batteries. Protective seals and pull tabs maintain battery freshness and simplify activation for immediate insertion. Sold in a practical pack of eight, these cells are convenient for routine replacement and household storage.

How to use

Before inserting a battery, remove it from packaging and peel off the pull tab to expose the air inlet; allow the cell to sit for a few seconds so the zinc‑air reaction stabilizes. Insert the battery into the hearing aid according to the device manufacturer’s orientation marks, ensuring firm but gentle placement. Close the battery compartment and check device function. Replace batteries as soon as audio quality declines or according to the hearing aid’s recommended replacement schedule. Dispose of used cells in accordance with local battery recycling and waste regulations.

Usage recommendations

Store unused batteries in a cool, dry place and keep them in their sealed packaging until needed. Avoid exposing zinc‑air cells to extreme heat or humidity. For best performance, insert a fresh battery at the start of the day and remove batteries from the device when not in use for extended periods to prevent leakage and corrosion.
