Like smartphones, laptops and tablets, Cochlear sound processors with rechargeable batteries use lithium-ion batteries. Not only are they better for the environment than disposable batteries, but they are also lightweight and offer a lot of power and energy for their size.
Battery life varies for every user, according to the programs you use each day, your implant type, the thickness of skin covering your implant, how often and for how long you stream from devices, and the size and type of battery used.
In any case, the amount of charge a battery can hold and the amount of power it can discharge decreases as the battery ages.
So, if you use rechargeable batteries, here are five ways to get the most from them.
1. Don’t let your batteries go flat
With older style rechargeable batteries, it was common to let the battery go completely flat before recharging, however this is not recommended for the newer lithium-ion rechargeable batteries used widely today.
In fact, letting them discharge completely may actually shorten their lifespan. So remember to recharge your batteries before they become completely flat.
2. Recharge your batteries fully
When you charge your batteries, ensure you charge them to their maximum capacity. You should also charge them fully before storing them.
3. Avoid extreme temperatures
Batteries don’t like excessive heat or cold. Exposure to very high or low temperatures can speed up the ageing process of your rechargeable batteries.
Avoid leaving them in hot environments, such as in direct sunlight or inside a parked car. Ideally, store your batteries at room temperature.
4. Cycle through your batteries
Do not store your rechargeable batteries for extended periods of time. If you have multiple batteries, it’s a good idea to rotate use of them all instead of using one and storing others.
5. Replace your batteries when indicated
Even with the greatest care, batteries will age and degrade over time.
When your battery doesn’t provide you with enough time on air for your needs, it’s time to consider replacing.
When a battery reaches the end of its lifespan and can no longer be charged sufficiently, the charger will let you know by a flashing orange indicator light. Make sure you replace your rechargeable batteries as soon as you need to.
