Understanding Size 312 Hearing Aid Batteries
Size 312 hearing aid batteries, also known as 13, are a popular choice among hearing aid users due to their compact size and reliable performance. These batteries are designed to fit seamlessly into smaller hearing aids, providing power for an extended period. Let's delve into the details of size 312 hearing aid batteries, their features, lifespan, and how to handle them.
Size 312 Batteries: Specifications and Features
Size 312 hearing aid batteries measure 7.9mm in diameter and 5.4mm in height, making them one of the smallest standard button cell batteries. They are typically marked with a '312' or '13' on the negative terminal. These batteries are zinc-air, meaning they require oxygen to function and have a tab that must be removed before use.
- Capacity: 70mAh
- Typical voltage: 1.45V
- Average lifespan: 3 to 7 days, depending on hearing aid usage and settings
How to Use Size 312 Hearing Aid Batteries
Before inserting a size 312 battery into your hearing aid, ensure you remove the protective tab. This allows oxygen to reach the battery, activating it. After removing the tab, wait about 5 minutes before inserting the battery. This allows the battery to develop a charge. Once inserted, your hearing aid should be ready to use.
Maximizing the Lifespan of Size 312 Batteries
To get the most out of your size 312 hearing aid batteries, consider the following tips:
- Store batteries at room temperature, away from extreme heat and moisture.
- Replace batteries in pairs to ensure consistent performance and prevent early battery drain.
- Turn off your hearing aids when not in use to preserve battery life.
- Regularly clean your hearing aids to prevent moisture and earwax from damaging the batteries.
Recycling Size 312 Hearing Aid Batteries
Once used, size 312 hearing aid batteries should be recycled to minimize environmental impact. Many communities offer battery recycling programs. Check with your local waste management department for recycling options in your area.
Comparing Size 312 Batteries with Other Common Sizes
| Battery Size | Diameter (mm) | Height (mm) | Capacity (mAh) |
|---|---|---|---|
| 312/13 | 7.9 | 5.4 | 70 |
| 10 | 11.6 | 5.8 | 170 |
| 312 | 7.9 | 5.4 | 70 |
As shown in the table, size 312 batteries are smaller than 10 (or 16) batteries but have a lower capacity. They are ideal for smaller hearing aids where battery size is a critical factor.
In summary, size 312 hearing aid batteries are a reliable power source for smaller hearing aids. By understanding their features, proper usage, and care, you can maximize their lifespan and ensure optimal performance. Always remember to recycle used batteries to protect the environment.
