How to help hearing aid batteries last longer
1. Let the battery sit for 5 minutes before placing in the hearing aid
Once you take the tab off the hearing aid you should let the battery sit for 4-5 minutes before placing it in the hearing aid and closing the battery door.
This will allow for the battery to fully activate. The battery is activated by air flow, when allowing it to sit for 4-5 minutes you are allowing the air to fully circulate through the battery to give optimal time of usage.
2. Keep your hands clean when changing the batteries
When you change the batteries, it is smart to wash your hands beforehand. This will prevent dirt and debris from getting into the battery compartment.
Therefore this will improve the performance of the battery.
3. Open the battery door at night
It is best if you open the battery door at night. This will turn off the hearing aid and preserve the battery life. The battery is naturally still draining, even with the battery door open, but at a much slower rate since it is not in active use.
4. Store your hearing aids in a cool dry place
When you store your hearing aids in a cool and dry place, such as a dehumidifier, this not only helps the hearing aid but also the batteries.
Batteries can be damaged by water or damp conditions. You are then helping the life of the battery by keeping it out of damp conditions.
5. Do not buy batteries in bulk
When you buy batteries in bulk you have to be aware of expiration dates and understand that battery life can still diminish on unopened batteries.
That is why it is best to get batteries in smaller increments (~6 months worth at a time).
6. Store the batteries you do have at room temperature
If you have unopened batteries it is best to store them at room temperature. Storing in extreme hot/cold areas can damage the battery.
Hot conditions are something to be extra cautious of, moisture can allow for the tabs on the battery to slip off and start activation of the battery before you would like it to (ex. storing in a hot car in the summer).
