Rechargeable vs. Non-Rechargeable Hearing Aids - What's Better?


Having the battery die on your phone or another mobile device can cause quite the headache. To mitigate our devices dying, we carry portable batteries everywhere we go for smart phones, smart watches, and even pulsometers to keep an eye on blood-oxygen levels for COVID.

In this article, we’re going to explore the differences and benefits of rechargeable vs. non-rechargeable hearing aids.

Two Types of Batteries

There are two types of batteries in our world of portable energy. Both have their advantages and disadvantages, and in many cases these are opposites:

  • Single use, that is non-rechargeable batteries are inexpensive because they are manufactured in huge quantities using cheap, abundant materials. They consume their store of energy as we use them. When we have used this up, they belong in the recycle box.
  • Reusable batteries, including those in rechargeable hearing aids are more expensive, because they use rarer materials and do not have the same economies of scale. When they are flat, we can replenish them from a suitable energy source. However, if we allow them to go completely to zero they lose some of their capacity.

There’s no middle ground between these two options. Social media posts claiming we can recharge single-use batteries are fake news. In fact, the practice is dangerous and could lead to overheating, fires, and even explosions.

Which is Better, Single Use or Rechargable Hearing Aid Batteries?

If you are in the market for a pair of hearing aids, then you’ll find the type of battery affects what’s available, and to an extent, the price. Ten years ago, very few manufacturers sold rechargeable hearing aids. Nowadays, everybody seems to be offering them, although only some have interchangeable battery technology.

This means you are generally stuck with one or the other for the life of your hearing aids. Read what follows carefully so you make the right choice for your lifestyle:

  • Rechargeable hearing aids are the right choice for people who are seldom far away from an energy source to replenish them. Many older people regard rechargeable batteries as their hassle-free solution.
  • Hearing aids with single use batteries are a better option for people who like to be out and about. If you enjoy trekking through wide open spaces, you need hearing aids that use single use batteries you find in packs in stores.

There are strengths and weaknesses to both options, although these are affected by personal life style. Non-rechargable and rechargeable hearing aids look the same so appearance is not a consideration.

What You Need to Know About Single-Use Battery Hearing Aids

Single-use battery hearing aids use disposable zinc-air batteries available in five different diameters and thicknesses. These generally last between five and twelve days, depending on the hearing aid type and the usage pattern.

These ‘button batteries’ are available on the internet, and in many drug and convenience stores. If you go on holiday to a remote place, carry a few spare packs in your baggage. They are non-flammable products and generally safe to use.

However, their performance degrades as they reach the midpoint of their charge and lower. This can happen with us scarcely noticing, until we start turning up the television again. Replacement batteries are small and fiddly, but manageable with reasonable eyesight.

What You Need to Know About Rechargeable Hearing Aid Batteries

There are two types of rechargeable hearing aid batteries on the market. Both keep going for at least a day with normal use, but may drain faster when using Bluetooth.

  • Silver-zinc rechargeable batteries are removable for recharging by hinging open the battery compartment, placing them in the charger and switching it on. Expect to replace them once a year. You could use single-use ones until you got around to doing so.
  • Lithium-ion batteries are sealed in the body of the hearing aid, and may last three-to-four years before replacing by a skilled technician. This is the most convenient technology for people who dislike fiddling with things, and prefer to pop their hearing aids in the charger.

The Cost Implications and Environmental Impact of Rechargeable Hearing Aids

Rechargeable hearing aids are slightly more expensive with the obvious exception of Blue Angels ones, where our huge turnover makes them significantly less expensive comparing like for like.

However, the real winners are both you AND the green movement after you purchase Blue Angels hearing aids. That’s because you won’t find yourself adding fifty-two batteries to the landfill every year. In fact, your batteries could last as long as your hearing aids if you care for them properly.
