How to make your batteries last longer?
1. Store your batteries at room temperature. Purchase a dehumidifier or dry aid kit. This will remove the moisture from the inside of your hearing aids and protect your batteries. Just make sure to remove the batteries before putting the devices in the dry aid kit so they don’t dry out.
2. After taking the tab off of zinc air batteries, let them sit for one minute or more, which can maximize their energy.
3. Remove the batteries from your hearing aids at night. If they remain in your devices and they are left on, they will drain power.
4. Clean the battery contacts – inside the hearing aids – with a cotton swab to dry them. If you see corrosion on the contacts or batteries, throw the batteries away immediately.
Hearing aid batteries last anywhere between 5 and 14 days depending on the above factors. In many new hearing aid models, you will know it’s time to replace your hearing aid batteries when the aids start beeping.
