How Often Should You Change Hearing Aid Batteries? A Comprehensive Guide

Hearing aids have completely changed how people with hearing loss see their surroundings. But when it comes to the batteries that power these devices, how often should you be changing them? In this guide, we'll uncover the factors that influence battery lifespan and provide you with valuable insights to ensure your hearing aids function optimally.

Understanding Battery Longevity:

When it comes to the longevity of hearing aid batteries, there is no one-size-fits-all answer. Several factors come into play, including the type of hearing aid, the size of the battery, and how you use your hearing aids. Let's take a closer look at how these variables impact battery life.

The Role of Battery Size:

The size of the battery is a crucial determinant of its lifespan. Different battery sizes are used in hearing aids, each with varying durations:

1. Size 10 Batteries: These are the smallest batteries and typically last for about 3 to 7 days.

2. Size 312 Batteries: Slightly larger in size, these batteries usually provide power for 3 to 10 days.

3. Size 13 Batteries: Larger in size, these batteries offer a longer lifespan, lasting approximately 6 to 14 days.

4. Size 675 Batteries: The largest among the options, these batteries can last the longest, often powering your hearing aids for 9 to 20 days.

However, it's essential to remember that these figures are approximate and can vary based on individual usage patterns and hearing aid specifications.

Factors Affecting Battery Life:

While battery size is a key factor, other elements also influence how long your hearing aid batteries will last:

Usage Patterns: The more you use your hearing aids, the quicker the batteries will deplete. Consider your daily wear time and the environments you're in.

Volume and Settings: Higher volume levels and advanced features like Bluetooth or noise reduction can drain batteries faster.

Moisture and Humidity: Exposure to moisture and humidity can impact battery performance.

Open vs. Closed Hearing Aids: Open-fit hearing aids tend to have longer battery life compared to closed-fit models. 

Ensuring Consistent Power Supply:

To ensure you always have a reliable power supply for your hearing aids:

Keep Spare Batteries: Carry spare batteries with you, especially if you're away from home.

Check Expiry Dates: Always check the expiration dates on batteries to ensure they're fresh and will provide optimal performance.

Consider Rechargeables: Some modern hearing aids use rechargeable batteries, eliminating the need for frequent replacements.

Consult Your Audiologist:

Every individual's hearing aid usage is unique. Consulting your audiologist or hearing healthcare professional is crucial for personalized guidance on battery management. They can provide tailored recommendations based on your hearing aid model, usage habits, and specific needs.

Changing hearing aid batteries is a fundamental aspect of maintaining your hearing aids' performance. By understanding the factors influencing battery life and implementing best practices, you can ensure your hearing aids consistently deliver the exceptional sound quality and comfort you rely on. Remember, the expertise of your audiologist is invaluable in navigating the nuances of battery usage for your unique hearing needs. For more information visit or call us on 96 5839 5839.
