Good working batteries are essential to a properly functioning hearing aid. The hearing aid batteries come in 4 standardized sizes: 10, 13, 312 and 675. Each number has a correlating color to make it easier to remember the correct size for your hearing device.
Hearing aid battery life is generally determined by the following factors: the type of hearing aid, the type of battery, the environment you live in and the number of hours in a day the hearing aid is used.
Keep these tips in mind to extend the life of your hearing aid battery:
- When starting a new pack of batteries do not remove the plastic tabs on the back of each battery until you are ready to use them. Hearing aid batteries are powered by zinc air, meaning they are activated by air. When the tab is removed you are essentially starting the battery.
- Store hearing aid batteries at normal room temperature. Years ago, putting batteries in the fridge made them last longer; the exact opposite is true with today’s zinc air technology. It is also good practice to store hearing aid batteries away from coins, keys and other metal objects because this may cause the batteries to short circuit.
- When the time comes to replace the battery in your hearing aid, wash your hands thoroughly. Grease and dirt on hearing aid batteries can cause damage to the hearing device.
- Once you remove the plastic tab on the back of the battery let it sit out for 1 minute. This allows the hearing aid battery to take in enough air to power up before it is placed in the hearing aid.
- Anytime the hearing aid is not being used, it should be turned off, placed in a safe spot and left with the battery door open. This minimizes battery drain and allows moisture to escape, which will keep the battery from corroding and damaging your hearing aid. If you don’t plan to wear the hearing aid for an extended period of time, it is a good idea to remove the battery entirely.
A few other things to keep in mind about hearing aid batteries:
- Like all batteries an unused hearing aid battery can last for many years, however each passing year the batteries’ power will be reduced. A new package of hearing aid batteries will always be strongest.
- Battery companies make millions of individual batteries every year and occasionally you will get one that doesn’t work as well as it is supposed too. When that happens, send the bad battery and the packaging back to the manufacturer, often times they will send you coupons or replacement batteries.
- Some hearing aid manufacturers offer rechargeable batteries and even rechargeable hearing aids, but they are not as popular as their zinc-air counterparts.
Most importantly, remember a hearing aid can’t help you hear if it doesn’t have the power it needs. Buy quality hearing aid batteries and keep in mind these easy tips to extend your battery life and you’ll be hearing all the sounds around you better than ever before.
