Hearing Aid Batteries and Battery Testers

When your hearing is less than perfect and you rely on some type of assistive listening devices to be able to hear properly and communicate well, it is important to be sure that your hearing aids are working at their best at all times. Making sure that the hearing aid batteries are in good shape is one of the most important aspects of ensuring that the hearing devices are working correctly so that you can enjoy better hearing.

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.

How long hearing aid batteries last will depend not only on the type of battery itself, but also on the kind of hearing aid products that the batteries are being used in, since some demand more power than others. Another factor in battery life is how long the aids are used each day.

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.

Many users say that they prefer to use a hearing aid battery testing device that shows not only if the battery is "live" or "dead" but also has a gauge that can indicate the amount of power remaining in the battery. It is also best if the model is durable so that it can withstand years of regular usage and if it can test more hearing aid batteries in pairs rather than singularly. Another convenience built into many testing units is a storage compartment that can hold spare batteries.
