FAQs
What does 'Zinc Air' mean for this battery?
Zinc-air batteries use oxygen from the surrounding air to power the electrochemical reaction. They require a small tab to be removed to expose vents that allow air in, activating the battery.
How long do these batteries typically last?
The lifespan varies based on the hearing aid's power consumption and usage patterns, but Rayovac Extra batteries are known for their long-lasting performance, often lasting several days to over a week per battery.
What is the shelf life of these batteries?
Freshly stocked Rayovac Extra Hearing Aid Batteries typically have a shelf life of 2-3 years from the date of manufacture, provided they are stored properly.
Can I use these batteries in devices other than hearing aids?
No, these batteries are specifically designed and optimized for hearing aid devices only. Using them in other electronics may result in poor performance or damage.
Why is the color code yellow?
The yellow color code is a universal standard for Type 10 hearing aid batteries, making it easy to identify the correct size and type for your device.
Are these batteries environmentally friendly?
Yes, these batteries are mercury-free, making them a more environmentally responsible choice compared to older battery technologies that contained mercury.
How should I store unused batteries?
Store unused batteries in their original packaging at room temperature in a cool, dry place. Avoid direct sunlight and high humidity.
Troubleshooting
Hearing aid not turning on after battery replacement
Ensure the protective tab has been removed and the battery has had a minute to activate. Check that the battery is inserted with the correct polarity (+/-). Try a new battery from the pack.
Hearing aid performance is weak or distorted
The battery may be low or depleted. Replace with a fresh, activated battery. Ensure the battery compartment is clean and the battery is making proper contact.
Battery seems to be draining faster than expected
Ensure the battery tab was removed only when ready for use. Check hearing aid settings, as higher amplification or wireless features can consume more power. Extreme environmental conditions can also affect battery life.
Battery won't fit into the compartment
Double-check that you are using the correct battery type (Type 10, yellow code) for your specific hearing aid model. Ensure there is no debris in the battery compartment.
