Troubleshooting
Hearing aid is not turning on after battery insertion
Ensure the protective tab has been removed and verify that the battery is inserted with the correct polarity.
Battery power depletes faster than expected
Check if the hearing aid volume is set too high or if the device has moisture buildup; also ensure the battery compartment is fully closed.

Setup, Compatibility & Care
To ensure optimal longevity, handle the batteries with clean, dry hands. Avoid touching the contacts of the battery with metallic objects, as this can cause a short circuit. When installing, ensure the positive (+) side of the battery aligns with the positive terminal of your hearing aid battery door. Store unused batteries in their original blister packaging in a cool, dry place between 10 °C and 30 °C. Exposure to excessive heat or cold can degrade the chemistry and shorten the service life of the battery.
