Why Do My Hearing Aid Batteries Die So Fast?

If you are like many people, you may be frustrated with your hearing aid batteries dying so fast. You may have even started to question if your hearing aids are defective or if they were made improperly. This article will address these concerns and shed some light on the situation. The five steps below should help you understand why this is happening and how to stop it from happening in the future.

Clean your battery contacts regularly

If your battery is not making good contact with the hearing aid, it will die much more quickly than usual. A simple way to clean them is with a dry cotton swab. You can also use an eraser for this purpose if you do not have any other supplies on hand.

Do NOT try to use toothpaste or baking soda for this process because they are too abrasive and may damage the contacts over time. Also, be sure that when you are cleaning off the battery after using the method above, be careful not to touch anything else but the metal parts of it! Even oils from your fingers could contaminate something like hearing aids which require very specific cleanings.

Remove moisture that has accumulated inside of your hearing aids

The moisture in the air around us can form condensation inside of hearing aids. It is especially likely to happen if you are using your device in a humid environment or during rainy weather. Unfortunately, this water vapor will corrode the battery contacts and severely shorten its lifespan. The best way to avoid these problems is by removing excess moisture from within the devices themselves. 

Do NOT use rice because while it does absorb some liquid, it doesn't do so completely and could actually cause corrosion over time! Several products on the market may help with this, such as desiccant packets (like those found in dry shampoo bottles), silica gel bags, and even small vacuum cleaners designed specifically to remove dust. Moisture can also accumulate inside of your charging case, so be sure to keep it closed tightly between uses.

Use fresh batteries regularly

Do not wait until you are down to one battery before changing them. You have probably heard that the best way to preserve a lithium-ion battery is by using partial charges instead of complete ones? Rechargeable hearing aids work in much the same way, so try your best to avoid draining it completely every time if possible.

There are also products on the market designed specifically for storing batteries, such as holders or cabinets. If you don't have access to these types of storage devices, then simply store your batteries somewhere where they will be less affected by extreme temperatures and won't come into contact with other metal objects regularly. Examples include places like bedrooms where there aren't usually major temperature changes throughout the day due to heating or air conditioning units being turned on or off.

Since some hearing aid batteries last longer than others, try only to buy the ones that you know will be able to power your devices for a long time and avoid buying more just before they die completely! While we can't control every aspect of how our batteries work, there are many things we can do to preserve their lifespan. 

If these steps don't help, then it may be worth contacting an audiologist who knows exactly why this happens with your specific device. Each one functions differently depending on its age, size and technology type, so your audiologist should have all of the answers in this regard.

Keep spare sets of fully charged batteries for emergencies

If you already know that something like the weather is going to cause your batteries to die more quickly, then why not have a set or two around just in case? They are easy enough to keep on hand, and they could save you from being completely stranded if this happens.

If none of these tips work well with your particular hearing aid battery brand, consider contacting an audiologist who works with many brands before making any final decisions about what else to try since each one functions differently depending on its age, size, and technology type. Be sure that when buying new batteries, you always choose the right size, type, and technology for your devices.
