Cochlear™ Sound Processor Battery Guide & Tips

How long will my batteries last and what affects their life?

Battery life varies for every sound processor user and is dependent on a variety of factors, like the age of the battery, programs and sound processor functions that you use every day, your implant type, sound environment and volume levels. The size and type of the battery has an impact as well as the thickness of your skin where it covers your implant. Streaming from compatible Apple or Android devices and using True Wireless™ devices can also impact your sound processor’s battery life.

Here’s a quick guide as to what you can expect from your sound processor’s batteries and practical tips to help extend your processor’s battery life.

What is the difference between battery life and battery lifespan?

It’s beneficial to understand the difference between battery life and battery lifespan. 'Battery life' is the amount of time your device runs before it needs to be recharged. 'Battery lifespan' is how long your battery lasts until it needs to be replaced.

How do I get the most out of my battery life

Please be sure to read these 6 tips to get more out of your battery life:

Don’t let your battery completely run down without recharging
In the past, rechargeable batteries needed to be fully run down before recharging. But the newer lithium-ion batteries used with Cochlear sound processors will actually have a shorter lifespan if you let them become completely flat before recharging.
Fully charge the battery with each charging cycle
Charge your batteries to their maximum capacity, and remember to fully charge your batteries before storing them.
Store batteries at room temperature if possible
Don’t leave your batteries in a hot car or in direct sunlight; they really don’t like excessive heat or cold.
Rotate your rechargeable batteries daily if you have several of them
Don’t use one battery and store the others for later. It’s better to rotate each battery each time you use it.
Replace your rechargeable batteries when needed
All batteries will degrade as they age, so when your battery no longer provides you with enough power for your daily needs, it’s time to replace the battery. Your sound processor will alert you to a low battery status.
Set your sound processor to turn off when you remove it
To save battery life, some processors, such as the Nucleus® 7 and 8 sound processors, allow your clinician to set the processor to turn off two minutes after you take them off. Ask your clinician for advice.

Find out if you are eligible for an upgrade to a newer sound processor.

New generations sound processors support improvements on rechargeable battery and power draw. Learn more about the latest models.
