Best Hearing Aid Batteries

Doctor with Hearing Aid

When it comes to your hearing aids, there’s one specific aspect that demands a lot of care and attention: the batteries. A lot of issues with these devices usually stem from poorly looked after hearing aid batteries, which is why we want to help!

In this article, we’re going to cover everything to do with hearing aid batteries. This includes some of the best types you can buy, how to make yours last as long as possible and when you need to change them. Carry on reading to find all of this information:

How do you find the best hearing aid batteries?

Hearing aid batteries are classified as zinc-air batteries. This means that they’re only activated once the zinc in the battery reacts with the air – this happens when you peel off the protective tab. There are many different brands out there that sell these batteries and the best way to differentiate the best from the rest is by looking at reviews and customer feedback.

However, your search should begin by determining the size. Different devices require batteries with different cell sizes and there are typically four different ones for you to buy:

  • Size 13
  • Size 312
  • Size 10
  • Size 675

You will know what size you require as it should say in your hearing aid instructions manual or on the packaging it comes in. If you’re ever unsure, just see your audiologist and they’ll tell you exactly what size you need.

Once you’ve figured out the size you need for your device, then you can start looking at the reviews and feedback for different brands. Often, it’s better to pay a little extra if it means you’re getting batteries that are proven to work best and last the longest.

How do you extend the life of your hearing aid batteries?

Even if you buy the best batteries on the market, there’s never going to be 100% certainty that they’ll last as long as they should. Primarily, this is all down to how you use your hearing aid and the maintenance plan you follow. With the right habits, you can definitely increase the lifespan of your batteries, ensuring you get excellent value for money.

So, here are a few things you should definitely start doing:

  • Only remove the tab when you’re about to use the battery. As soon as it's removed, the battery will become active, meaning the power will drain. Don’t make the mistake of peeling the tab off if you’re not going to use the battery right away!
  • Wait five minutes before putting your battery inside the device. When we said you need to use the battery right away, we didn’t literally mean the second after you activate it. Instead, many audiologists have proved that waiting five minutes leads to optimum power usage. It allows the battery to fully activate, which then means it can last a good few days longer than usual.
  • Keep your batteries at room temperature all the time. This goes for any batteries that you’re not using; keep them away from heat or cold air. Exposure to the wrong climate is probably the easiest way to lower the life expectancy of your hearing aid batteries.
  • Open the battery door when you’re not using the device to prevent corrosion and battery depletion. All you need to do is open the compartment and allow your batteries to breathe, this will stop moisture from getting trapped inside. Turn off your hearing aids as well or else they’ll just waste battery power. Also, you should remove the batteries if you’re not using the device for a day or two.

Follow these four tips if you want to get the most out of your batteries and extend their life by a few days.

When should you change your batteries?

On average, hearing aid batteries can last as long as three weeks or as little as three days. It depends on how well you look after them, the battery brand and so on. They should be changed when they start running low on power as a drained battery can cause your device to malfunction.

Typically, a good rule of thumb is to change your batteries when you notice any sound distortion or the volume isn’t as loud as it used to be. Any changes in performance are key indicators, so watch out for them. When this happens, you should see your audiologist to get replacements. They’ll help you find the best ones and can also check your device to ensure it’s still working correctly and any performance issues are just battery related.
