Hearing aid battery life isn’t completely under our control. Batteries will run out at different speeds depending on how often you use your hearing aid, what type of battery you have, and what type of hearing aid you use.
However, there are a few tips that, if you follow them, will at least help you get the most life out of your batteries as possible.
Let the battery breathe.
Did you know that when you open a new battery and pull the tab, you should let the battery sit out for about five to ten minutes to “breathe”? That may sound funny, but it’s true! When outside air hits the materials inside the battery, it activates them. Putting your battery into the hearing aid too soon can shorten the battery life by a few days.
Wash your hands.
Wash your hands any time you change the battery or open a package of batteries. Oils and grime from your hands can clog up the battery (remember- it has to get air!) or damage it.
Keep your batteries at room temperature.
You may have heard that batteries last longer if you store them in the refrigerator. The thought is that the cooler temperatures will slow down the power leakage from the battery. But with hearing aid batteries, the refrigerator does more harm than good. Hearing aid batteries need to stay very dry, and the refrigerator creates condensation. This can lead to corrosion or shortened battery life.
Keep your batteries (and hearing aid) dry.
Speaking of staying dry, keep your batteries dry, even once they are in inside your hearing aid. Using a hearing aid dehumidifier can prolong battery life and increase the efficiency of the hearing aid itself.
Use fresh batteries.
If you keep pushing that one pack of batteries to the back of the drawer, by the time you pull it out and use it, you may not get as much life out of them as you’d like. Make sure you are using your batteries in the order that you purchased them, so none of your packs have a chance to sit around and lose power.
Open the door.
When you aren’t using your hearing aids, open the battery compartment door. This will keep the batteries from draining, and it will also encourage airflow and help with the moisture problem we’ve already discussed.
Take your batteries out.
If you’re not going to use your hearing aids for a long time, go ahead and take the batteries out. This gets even more air flowing than opening the compartment door, and is an even better way to prevent corrosion and moisture build up.
