No more disposable batteries 

The most common reason for choosing rechargeable hearing aids is to avoid having to deal with disposable batteries. Users will not need to head off to the shops to purchase new batteries, saving time and money. Clients will often spend up to $100 a year on disposable batteries, even more if they regularly stream content from Bluetooth devices. When considering this, rechargeable hearing aids become a more cost-effective option in the long run. 

Additionally, rechargeable hearing aids make it easier to self-manage. This can be particularly useful for those with vision and dexterity issues. Some older clients may struggle with replacing the small batteries and may find it a frustrating process. Most of these clients may then need a carer or family member to assist. Rechargeable hearing aids help the client to reclaim some of their independence. The hearing aids can be simply dropped into the charger and left overnight to be charged – no fiddling with cables is required.

Full day of charge

Modern rechargeable hearing aids will give you at least 24 hours of continuous use, inclusive of time spent streaming, from one overnight charge. As long as you remember to charge overnight, you will never be caught off guard with a dead battery during the day.

More resistant to daily use 

Modern lithium ion hearing aids are completely sealed. This means they have a higher IP rating and more resistant to dust and moisture. This reduces maintenance issues, improves the performance and increases the life of the hearing aids.

Difference between current (Li-ion) over older gen batteries

The previous generation of rechargeable batteries were Silver-Zinc batteries. Similar to the Lithium-Ion batteries, they will give about 24 hours of usage. The battery compartment isn’t sealed so it can be easily switched out to another rechargeable battery. However, the major drawback is that the battery typically only lasts for a year before it needs to be replaced. This means more frequent maintenance and ongoing costs.


Battery life

As with all batteries, performance will degrade over time. Lithium ion batteries will typically last about 5 years before issues occur. At around this time, the battery will need to be replaced. Although performance will suffer, the battery will still continue to provide power but its capacity will degrade over time.  

Sealed case 

Because modern lithium ion hearing aids are completely sealed. If the battery experiences any issues or reaches the end of its battery life, it cannot be replaced by the user and will need to be changed by the manufacturer.
