Hearing Aid Batteries

The advancement of hearing aids has led to more complex battery types. Despite the innovation, batteries still maintain an easy to identify color and number code. Dove Hearing Center stocks battery types for several hearing aid models, old and new. This makes the clinic a convenient spot for device wearers that need access to extra parts.  

Battery types

The most common sizes are orange (#13), brown (#312), yellow (#10) and blue (#675). Knowing which battery type is compatible will prevent device damage. The color and number system were created as a helpful guide when making a battery purchase. But even in a worst-case scenario, damage will only occur when the wrong batteries are forced into the hearing device. Before installing a new battery, wearers should doublecheck the color and number for compatibility. Regularly replacing batteries keeps hearing aids at their optimal performance.

Rechargeable hearing aids

Rechargeable hearing aids follow a different set of rules than normal hearing devices. Rechargeable batteries never have to be changed when they deplete. Instead, the hearing aid is loaded into a portable station that charges the batteries back to full capacity. It is a convenient feature that is only available on select models.

Rechargeable devices are a great alternative for wearers with arthritis. It gets rid of tedious battery changes while also improving the overall efficiency of the device. Rechargeable hearing aids have better power-saving routines to take full advantage of usage habits. The longer the device is used, the more optimized it becomes when draining the battery.  

How to care for batteries

Hearing aid batteries use zinc-air technology. It is activated with oxygen that passes through holes in the filter of the battery. When activating for the first time, users should let the battery sit out for a few minutes. This allows it to work at maximum capacity without any problems.

Batteries should be stored in a safe place until they’re ready to be used. Avoid direct sunlight, high temperatures and damaged packages. Always clean the device to make sure it is clear of earwax and debris. When changing batteries, a blockage can seep into the compartment and cause damage. Following normal care instructions for hearing devices is a natural way to extend the life of a battery.
