FAQs
How long do VARTA Hearing Aid Batteries 312 typically last?
Battery life varies depending on the hearing aid's power consumption and usage patterns. However, VARTA batteries are designed for reliable, long-lasting performance.
Are these batteries rechargeable?
No, VARTA Hearing Aid Batteries 312 are single-use batteries and are not designed to be recharged. They must be replaced once depleted.
What does '312' refer to?
The number '312' refers to the standard size code for these hearing aid batteries. It indicates the dimensions and color coding (typically brown) used to identify them.
Why do I need to wait after removing the tab?
The colored tab protects the air-activated Zinc-Air cells. Removing the tab allows air to enter, initiating a chemical reaction that powers the battery. Waiting allows this reaction to stabilize for optimal performance.

Yes, these VARTA batteries are mercury-free, making them a safer and more environmentally friendly option compared to older battery technologies.
Can I use these batteries in other devices?
These batteries are specifically optimized for hearing aids. While they might fit in other small devices, their performance and longevity are best ensured when used in compatible hearing aid devices.
How should I store unused batteries?
Store unused batteries in their original packaging in a cool, dry place between 10°C and 30°C, away from direct sunlight and metal objects.
Troubleshooting

Ensure the colored tab has been removed and wait at least one minute for activation. Verify the battery is inserted correctly with the correct polarity.
