Battery life is one of the most important practical considerations when choosing a hearing aid. Nobody wants their hearing aid to die in the middle of an important conversation or family gathering. Understanding how long different batteries last will help you plan ahead and choose the right hearing aid for your lifestyle.
Hearing aid batteries come in standardized sizes, each color-coded for easy identification. The battery life depends on the size, the hearing aid's power requirements, and how many hours per day you wear your device.
Disposable Battery Sizes Explained
Size 10 (Yellow Tab) - 3 to 7 Days
The smallest hearing aid battery, used primarily in CIC and IIC hearing aids. Due to its compact size, it holds less power and typically lasts 3 to 7 days with 12-16 hours of daily use. Signia CIC models use this battery size to maintain their ultra-small form factor.
Size 312 (Brown Tab) - 3 to 10 Days
A popular mid-size battery used in many RIC and smaller BTE hearing aids. It offers a good balance between size and longevity. With typical use, expect 3 to 10 days of battery life. Many Signia RIC hearing aids use size 312 batteries.
Size 13 (Orange Tab) - 6 to 14 Days
Used in standard BTE hearing aids, size 13 batteries are larger and last significantly longer. They are a popular choice for users who want fewer battery changes. Many Signia BTE models like the Motion series use this size.
Size 675 (Blue Tab) - 9 to 20 Days
The largest hearing aid battery, used in high-power BTE devices for severe to profound hearing loss. These batteries offer the longest life of any disposable option, often lasting two to three weeks.
Rechargeable Hearing Aid Batteries
Rechargeable hearing aids have become increasingly popular, and for good reason. The Signia Pure Charge and Go series uses lithium-ion batteries that provide a full day of hearing on a single charge. Simply place your hearing aids in the charging case overnight, and they are ready for the next day.
Key advantages of rechargeable hearing aids include:
- Convenience: No more buying, storing, or fumbling with tiny batteries.
- Cost Savings: Over the life of the hearing aid, you save thousands of rupees on disposable batteries.
- Environmental Impact: Fewer batteries going to landfill.
- Reliable Power: Lithium-ion batteries maintain consistent performance throughout the day, unlike disposable batteries that gradually weaken.
What Affects Battery Life?
Several factors can shorten or extend your hearing aid battery life:
- Streaming: Using Bluetooth to stream phone calls or music drains batteries significantly faster, sometimes reducing life by 20-30%.
- Volume Level: Higher volume settings require more power.
- Humidity: Pakistan's humid climate, especially during monsoon season, can affect battery performance.
- Temperature: Extreme heat or cold reduces battery efficiency.
- Advanced Features: Noise cancellation, directional microphones, and tinnitus masking use additional power.
How to Know When Your Battery Is Low
Most modern Signia hearing aids provide low-battery warnings. You will typically hear a series of beeps or tones when the battery has about 30 minutes to 2 hours of life remaining. Some models connected to the Signia app will also send a notification to your smartphone, giving you time to prepare a replacement.
