The key to keeping hearing aids cost effective hinges on just one component–the batteries. It’s one of the biggest financial worries consumers face when shopping for hearing aids because the costs of replacing them can add up fast.

Even more worrying, what if the batteries die at absolutely the worst moment? This is a huge problem even for rechargeable brands.

In order to avoid the need to exchange the batteries several times a week, you can do several things to increase their life. Consider these six straightforward ways you can make those batteries last just a little bit longer.

1. Be a Smart Hearing Aid Consumer

When you first start to shop for your hearing aids is when it all starts. Brand quality and hearing aid features are just a couple of the factors which determine battery life. And some batteries are better than others. Some cheaper hearing devices have low quality parts that work with cheaper cell batteries. Be sure to talk this over this with your hearing care specialist because you will be switching out the batteries a lot.

Consider what features you need, and make some comparisons as you look around. You’ll find that non-wireless hearing aids come with batteries that can last two times as long as the wireless models. The larger the hearing aid, the longer the battery will last, too. These larger devices can possibly go for a couple of weeks without needing new batteries as opposed to the smaller ones which will require battery replacement every two days. Understand how all of the features of a hearing aid impact the power usage and then choose the ones you require.

2. The Hearing Aids Need to be Stored Properly

In most situations, the manufacturer will suggest opening the battery door at night to avoid power drainage. Also, you will want to:

A dry, cool place is where you should store the batteries. Battery cells are adversely affected by high temperature and humidity. The main thing is to keep them away from heat sources like light bulbs. Room temperature is okay.

Also, a dehumidifier is a smart idea. It’s one of the best ways to protect both the hearing aids and their batteries. Their delicate components are easily destroyed by moisture in the air.

3. Take Precautions When Changing the Batteries

Start with clean, dry hands. The quality of the battery is negatively affected by humidity, grease, and germs. Don’t forget to leave the plastic tab in place until it’s time to use the new batteries, too. In order to power on, current hearing aid batteries mix zinc with air. You don’t need that to happen before you are ready.

After you pull the tab, but before you put them in, it’s good to let them sit out for 5 minutes. The battery could be prolonged by days if you do this.

4. Play Around With Different Batteries and Battery Sources

Quality batteries have a longer life than bargain ones, obviously. Don’t only think about the brand, though, but what types of hearing aid batteries you’re using and also where you purchase them. If you buy in quantity, you can get good batteries for less at some big box stores.

Be careful if you buy them online, especially from an auction site such as eBay. Batteries have sell-by and expiration dates. You shouldn’t use them once they expire.

The easiest way to find batteries at an affordable price is to ask your hearing care specialist.

5. Be Ready For The Inevitable

Sooner or later, the batteries are going to quit. If you don’t want to find yourself in a pinch, it’s better to get an idea when this will happen. Keep a schedule of when you change the batteries and when they fizzle. You’ll get an idea of when you need to replace them over time.

A diary will also help you figure out which brands are right for your hearing devices and what features most affect the battery life.

6. Consider the Alternatives to Batteries

One of the best things about newer hearing aids is that some are rechargeable. If you can save money on batteries, it will be worth paying a little more initially. Rechargeable batteries are likely the best option if you need a lot of features like Bluetooth or wireless.

The batteries that make hearing aids work can be as significant an investment as the hearing aids themselves. A small amount of due diligence goes a long way to lengthening the life of those batteries and saving you money. Contact a hearing aid retailer for some information on what option is best for you.
