Setup and Installation

Rayovac Extra Size 312 batteries feature child-resistant packaging to enhance safety. Follow these steps to safely access and install your batteries:

1. Opening the Packaging: The battery packaging is designed to be child-resistant and requires scissors to open. Carefully cut along the indicated line on the package to access the battery wheel. It is recommended to perform this over a table to prevent batteries from falling.

2. Removing a Battery: Once the package is open, carefully remove one battery from the wheel.
3. Activating the Battery: Rayovac Extra batteries are zinc-air batteries. They are activated by air. Remove the protective tab from the back of the battery. For optimal performance, allow the battery to sit un-tabbed in the open air for approximately one minute before inserting it into your hearing device. This allows air to fully activate the zinc-air chemistry.
4. Inserting into Device: Refer to your hearing aid's instruction manual for specific guidance on how to correctly insert the battery. Ensure the battery is oriented with the correct polarity (+/-) as indicated by your device.

Operating Instructions

Once properly installed and activated, your Rayovac Extra Size 312 batteries will power your hearing aid. The lifespan of the battery will vary depending on the hearing aid model, usage patterns, and environmental conditions.

• Power Indicator: Most modern hearing aids have a low battery indicator. Replace the battery when this indicator appears or when you notice a decrease in sound quality or volume.
• Consistent Performance: Rayovac Extra batteries are designed for consistent power output throughout their life cycle.

Maintenance and Storage

• Storage: Store unused batteries in their original, unopened packaging at room temperature, away from direct sunlight and extreme temperatures. Do not refrigerate.
• Handling: Always handle batteries with clean, dry hands. Avoid touching the activated side of the battery (where the tab was removed) with your fingers, as oils and dirt can affect performance.
• Device Care: When not using your hearing aid, open the battery door to conserve battery life and allow moisture to escape, which can help prevent corrosion.

Troubleshooting

• Hearing Aid Not Working:
  • Ensure the battery tab has been removed and the battery has been allowed to air activate for one minute.
  • Check that the battery is inserted correctly with the proper polarity.
  • Verify the battery door is fully closed.
  • Try a new battery. If the issue persists, consult your hearing aid's manual or a hearing care professional.
• Short Battery Life:
  • Ensure the battery tab was removed just prior to use and not prematurely.
  • Check for excessive moisture or extreme temperatures, which can reduce battery life.
  • High-drain features on your hearing aid (e.g., streaming, Bluetooth) can consume more power.
  • If consistently experiencing short life with new batteries, consult your hearing care professional to check your device.
