Cochlear Implant Vs. Hearing Aid
Hearing aids and cochlear implants allow those who are hard of hearing to enjoy & perceive sound with clarity. Both of these devices accomplish this task in different ways. Hearing aids allow the user to hear better by amplifying the sound around them in order to be more easily heard and understood. Cochlear implants work by sending electrical signals to the brain which are then in turn decoded as sounds by the brain. These devices also have different needs when it comes to batteries. If you try to utilize regular hearing aid batteries in a cochlear implant device, you may find the battery not lasting very long or the device underperforming. This is due to the fact that cochlear implants utilize a significant amount more power than normal hearing aids.
When looking for batteries for your cochlear implant it is important to choose batteries that have the necessary extra power, to allow your device to function properly. These batteries are usually easily identifiable with a +P. For example, a Size 675 battery that has the extra power for implants will most likely be labeled a Size 675P battery. Using a battery without sufficient power for your implant device can result in low service life, unclear sounds, or even damage to your device. Always double check with your instruction manual to ensure you are using the right type of battery for your device.

Tips And Tricks: How To Extend The Life Of Hearing Aid Batteries
Proper Storage
Hearing Aid Batteries should be stored at room temperature, and at low humidity levels. They should remain in their protective packaging until ready to use to avoid early priming and unwanted self-discharge. By properly storing the battery, you can ensure it is as fresh as possible when needed for use. It is also important to only purchase hearing aid batteries from high end retailers to ensure that they have been properly stored. Here at microbattery.com we store our batteries in a climate controlled warehouse with 24/7 air conditioning. We also cycle or battery stock regularly to ensure that batteries do not sit for extended periods of time.
Priming The Battery
The biggest mistake that users of hearing aid batteries make is skipping the priming step before using the battery. Zinc-Air batteries utilize air to properly activate and ensure proper performance. To allow air into your hearing aid battery simply remove the protective color coded tab on the battery cell and let it sit out for a few minutes. This will allow air to flow through the cell and activate the chemicals inside, which will allow full power to be utilized.
Clean Connections
Before inserting a new battery into your device, it is good practice to wipe off any connections in the device as well as the connection points on the battery. This will ensure a clean connection that is free of resistance causing gunk. The more resistance to the flow of energy, the less efficiently it will power a device.
