The length of time the battery will last depends upon the type of battery, the type of hearing aid and also how often the hearing aid is used and the volume which it is set at.
To ensure that your battery lasts as long as possible, simply open the battery door when the device is not in use, which disconnects the battery and preserves its power.
It is important to use the correct battery size for all hearing aids. The colour of the battery pack reflects the size of the battery that is required. It should never be necessary to force the door of the battery compartment to shut. This could cause permanent damage to the hearing aid. If the compartment will not close, check that the battery is inserted correctly and is the correct size for the device.
Only remove the protective tab when fitting a new battery to the device.
Remember to always keep spare batteries handy. Modern batteries do not fade. Instead, they provide maximum power, until they simply stop working. A warning beep may sound when a battery replacement is required.
Finally, it is every bit as important to keep hearing aids batteries away from children and pets.
By following these simple tips, concerning hearing aid battery maintenance you can enjoy assisted hearing for the longest possible period of time and improve your quality of life, regardless of hearing loss.
