Hearing aids can change your life! But you have to remember that these devices also require proper care and maintenance for extended use. You must learn to extend the juice of your hearing aids’ batteries, even change them, when needed.
Before we proceed to the effective tips in extending the life of your hearing aids’ batteries, let’s take a look at their average life. On average, these batteries last for 3-7 days with the actual number being dependent on several factors. These include the type and size of the hearing aids, the type and size of their batteries, and the number of hours the hearing aids are used, among others.
Use the Oldest Batteries First
Batteries for hearing aids last for several days but these also have their expiration dates. You should always check the expiration dates on batteries, if any, so that you’re aware of when to use them. You must also remember that the longer these batteries are stored, the shorter their usable life will be.
For this reason, you have to use the oldest pack of batteries first. This way, the spare batteries in your purse will always be usable. Store spare batteries in a dry room, which should neither be cold nor hot; refrigerators and bathrooms are then unsuitable places for battery storage.
Turn Off Your Hearing Aids When Possible
Obviously, the batteries’ juice will be conserved when the hearing aids are turned off. You must then remove your hearing aids from your ears and turn them off, whenever possible. These instances include before going to sleep, taking a shower or bath, and relaxing in a quiet environment.
If you won’t be using your hearing aids for an extended period, you should remove the batteries from the battery compartment and place them in a dry area. This aids in preventing corrosion to their metal parts, among other possible damage caused by trapped moisture.
But if you will be using your hearing aids shortly after turning them off, you may want to consider leaving the battery compartment open. The excess moisture that has accumulated inside the compartment can then evaporate and, thus, there’s less risk of corrosion on the batteries. Plus, it decreases battery drain.
Again, place your hearing aids with their battery compartment open in a safe and dry place! Placing in on the kitchen sink or bathroom sink will defeat the purpose, not to mention that the hearing aids can become wet.
The way batteries are handled upon opening also make a difference. Wash your hands before replacing the old batteries so as to avoid getting dirt on the new batteries and the hearing aids. Avoid removing the plastic tab on a battery pack when the batteries won’t be used immediately. Wait for 5 minutes and let the new batteries sit, so to speak, before placing them into the battery compartment.
