Hearing aid batteries RAYOVAC Size 13 (PR48) Zinc-Air — 80 pack

RAYOVAC Size 13 (PR48) zinc‑air hearing aid batteries come in an 80‑cell pack intended for regular replacement in compatible behind‑the‑ear and in‑the‑ear devices. These cells use a zinc‑air chemistry that activates when the protective tab is removed, delivering a stable voltage profile suitable for many analogue and digital hearing aids. The larger pack size is convenient for users who replace batteries frequently or for caregivers managing multiple devices, reducing the need for frequent reordering.

Advantages

These RAYOVAC Size 13 batteries offer consistent output throughout the discharge cycle, helping maintain clear audio and device functionality. The zinc‑air chemistry provides a balance of capacity and reliable voltage under typical listening loads, and the individual cells include a protective sticker to delay activation until ready for use. An 80‑cell pack reduces per‑replacement handling and is practical for households or clinics that require a steady supply.

Suitable for

• Behind‑the‑ear (BTE) hearing aids compatible with Size 13 batteries
• In‑the‑ear (ITE) and receiver‑in‑canal (RIC) models designed for PR48 cells
• Frequent battery replacement schedules and multi‑device use

Key specifications

• Battery chemistry: Zinc‑air cell
• Physical size: Size 13 / PR48 format
• Typical application: Disposable hearing aid power source
• Pack quantity: 80 individual cells
• Activated by removing protective sticker

How to use

Remove one cell from the blister pack and peel off the protective tab to allow air into the cell; a brief wait after activation lets the battery reach optimal output. Insert the battery into the hearing aid according to the device manufacturer’s polarity markings, ensuring correct orientation. Replace batteries in safe, dry conditions and dispose of used cells according to local battery recycling guidelines.

Usage recommendations

Store unopened packs in a cool, dry place and avoid exposure to extreme heat or moisture. Keep spare batteries in their sealed packaging until needed to prevent premature activation. If a hearing aid exhibits intermittent sound or reduced volume, check the battery contact points and replace with a newly activated Size 13 cell.
