Forget 312 Batteries – Why You Should Start Thinking About Rechargeable


When you have a hearing aid to wear, there are a number of factors that you need to bear in mind in order to ensure that you are looking after it and taking care of it in the long-term. If you are not looking after it, it is not going to last as long and that can interrupt your ability to hear properly, which can itself have all sorts of knock-on effects throughout your adult life.

One of the issues to be aware of is batteries. There are all sorts of options when it comes to choosing batteries for your hearing aid, and it’s important to know the ups and downs, pros and cons of each type.

In this article, we are going to discuss a few possible reasons why you might specifically want to move away from 312 batteries, and instead start thinking about using rechargeable batteries in your hearing aid. You’ll find that there are quite a few convincing reasons, and that it is very much the best option on the whole.

312 Batteries: What Are They and Why Are They Not the Best Choice?

So first, what are 312 batteries, and why might they not be your number one choice when it comes to a hearing aid battery? 312 batteries are the most common and most instantly recognizable battery type for hearing aids, and you have certainly seen them many times before – especially if you are a hearing aid wearer and have been for a long time.

A 312 battery is a zinc-air battery, which becomes activated on exposure to oxygen. That’s why you have to pull the tab off the back of the battery before you can use it. The moment that it is oxygenated in this way, it will begin to drain power. This means that the battery is draining even if you are not actively using it – and even when your hearing aid is sitting in a drawer overnight in its case!

Because of this, these kinds of disposable batteries are famous for not having a very good lifespan. This can be frustrating, especially when you rely on them – and your hearing aid – in order to live a full and happy life. Many reports claim that 312 batteries last only around 12 days at the very most, and sometimes only as little as three days, which obviously means you will have to replace them very regularly. That can be a hassle, one that you would probably rather avoid if at all possible.

As you can see, it is quickly starting to look as though these outdated 312 batteries are perhaps not quite the best way to go. So, what is the alternative?

Rechargeable Batteries: The Way Forward

Instead of using 312 batteries, you might instead want to think about using rechargeable batteries, as these are likely to be a lot better in quite a few respects. In particular, and most of all, a rechargeable battery is going to last longer in the first case than you might assume. It used to be that they did not last long at all, but these days a rechargeable battery is likely to last you around 24 hours before needing a recharge. That means that you can expect it to last you the whole day, and you simply need to charge it overnight.

That is clearly a lot less hassle. Moreover, you’ll find that the charging is simple and easy to do, as you don’t actually need to do much except simply placing the batteries on to charge on a tabletop unit. This means that you can easily recharge your batteries as necessary, without any trouble at all.

Clearly, this is much better than the traditional 312 batteries. But there is another major reason why you might want to consider using rechargeable batteries in the future – they are also more eco-friendly. After all, you are not producing anywhere near so much waste when you are using batteries that you can recharge and you don’t have to worry about overusing energy either. This is a great thing to realize for the modern hearing aid wearer who wants to limit their impact on the environment.

As you can see, rechargeable batteries really are the way forward, so consider getting some for your hearing aid as soon as possible.
