For anyone who relies on any kind of assistive listening devices to augment their hearing, it is very important to take extra measures to be sure that the hearing devices are always working at an optimal level. Hearing aid batteries are a very fundamental aspect of ensuring that hearing aids are functioning correctly and fully for the best benefit and to make sure that you enjoy a better hearing environment.
There are many different sizes and models of batteries for hearing aids and they are unique to the particular model of hearing aid that you have. Normally, when you are first fitted for them, they will come with a set of batteries pre-installed and with a couple of additional sets of back-up batteries as well.
The life expectancy of various types of hearing aid batteries will be different according to both the type of battery itself and also the kind of hearing device in which it will be used. The amount of time that a hearing aid is used each day on a regular basis will also play a role in the life of the battery.
A general rule of thumb is that the batteries for them should be changed every ten days to two weeks, although you may find that you need to change them more frequently or less frequently. It is a good idea to keep track of how often you need to change them so that you can identify a pattern, in order to anticipate the supply that you will need to keep on hand.
In order to help you get the maximum use from a set of batteries for them, it is often useful to purchase a hearing aid battery tester. Such a battery testing device can help you identify the point at which your batteries have begun to lose power and are at a level where they need to be replaced. This is a better method than simply trying to listen to changes in the quality of the sound you are hearing through the hearing aids.
Another reason why this is important is because, as the batteries for them lose power, the assistive listening devices are not able to work at their optimal level of performance. When this happens your hearing can actually be damaged more by wearing them with worn out batteries because of distortions that can result.
A good battery tester can also be useful in troubleshooting when your hearing aid products develop some type of problem. Using a tester will quickly show you if the problem you are having is simply a matter of drained batteries or if there is some other problem that is not related to the batteries at all. This should also help avoid throwing out perfectly good batteries in the course of trying to fix the problem.
The best type of hearing aid battery tester will include some type of readout that shows you on a scale the amount of life that is left in the batteries. It should also be a good, durable model that will last for many years of consistent usage and it will be most convenient if it holds multiple hearing aid batteries. There are even some models available that have storage compartments where you can keep your spare batteries.
