When you rely on a hearing aid for everyday use, drained batteries leave you disoriented and trying to cope until you can get the right replacements. Maximizing the lifespan of each set of hearing aid batteries saves money and eliminates at least some of those late night trips to the pharmacy. Learning the four most common reasons the batteries run down faster than usual could help you get more out of each set.
Each extra feature added to a basic hearing aid increases the power it needs to run. These features include
- Direct audio input drivers for connecting the device like a pair of headphones
- Directional amplifiers to pick up sounds from certain directions at a higher volume
- T-coils to prevent high pitched feedback from telephones and other microphones
If you don’t use or need these features, consider switching to a simpler model without them or simply turn them off. Running as few extra features as possible helps your hearing aid batteries last as long as possible.
Loud Noise Levels
The amplification process that allows a hearing aid to help you responds to the noise levels around you. If you go to a rock concert or spend your day monitoring a playground where the kids scream constantly, you’ll see a major drain on your batteries because high noise levels use more power than low ones. Limiting the time you spend in very noisy environments is also good for your aural health, aside from reducing power loss in your hearing aid.
Like most closed cell batteries, hearing aid power sources are very sensitive to humidity levels. Low humidity causes the battery to dry out, especially the common zinc air type that create electricity by reacting with oxygen. High humidity can cause voltage leaks too, so both high and low levels of moisture in the air leave your battery dead before its time.
You know to take your hearing aid out at night to keep ear wax from clogging up the speaker holes. However, do you remember to take the battery out too? Removing the battery and storing it in a separate sealed container reduces drain when the device is not in use.
Saving money on hearing air batteries is especially important when you rely on a medical device that uses an unusual or hard-to-find battery type. Save money and time by maximizing the use you get out of each set of batteries. If you’re not sure whether the hearing aids you’re using are adequate, you may wish to undergo a Union Hearing Aid Centre Limited hearing test.
