The advent of hearing aids many decades ago was a great blessing to the numerous people who had a hearing loss to one extent or another. However, no matter what kind or style of assistive listening device a person uses, all of these important hearing units are dependent upon minute batteries for power. For this reason, making sure that the hearing aid batteries are in good working order is always a high priority for hearing aid users.
There is a wide array of different styles, models and brands of hearing aid products on the market and as a result there is also a wide array of hearing aid batteries that are designed to work with these different models of hearing devices. It is important to be sure that the correct type of hearing aid battery is purchased for the hearing instrument or there can be damage, not only to the device but also to the hearing of the person wearing the device with the wrong battery.
All types of hearing aid batteries are round in shape and quite small. This has added to the possibility of becoming confused over the right battery model. To help with this, all batteries have an engraved model number on the surface and that also identifies the voltage of the cell and the manufacturer.
The problem with the etchings that are engraved on these batteries is that they are also very small and often extremely difficult to read. As a result, in addition to the etchings to help identify the different models of batteries, they are also marked with colored bands around them. These colored bands help to further distinguish the various battery models, so that they can more quickly and easily be recognized, reducing the risk of confusion between models.
When purchasing batteries for hearing aids, the packaging that holds them usually has large and easy to read markings to help people be sure they are getting the right model of battery. The main problem can be trying to read the engraving of the existing battery in the hearing aid because it is so small.
A good tip is to write down the exact model on a card that you carry in your purse or wallet, so that you always have it on hand when at the store. This simple tip can help to reduce errors when buying batteries for your hearing aid products, which will not only reduce problems with having the wrong battery but will also save money in the long run.
The general life span of hearing aid batteries depends on the size of the battery itself. Larger batteries will generally have longer life spans than the smaller batteries. However, this is not always the case because there are some hearing aids that simply draw more power in order to operate correctly.
