How humidity, temperature and altitudes can affect hearing aid battery life

If you’re a hearing aid user, have you ever wondered why the life of the battery in your device changes when you go on holiday in a different climate? Or perhaps you’re a keen walker or mountaineering enthusiast and have noticed battery life on your hearing aid is affected the higher you climb?

Paul Deeble, Technical Liaison Manager at leading hearing aid battery manufacturer RAYOVAC©, talks about how certain environments can affect the life of your hearing aid battery.

Humidity & heat

The humidity within an environment can affect your hearing aid’s battery life.

Paul explains: “Hearing aid batteries contain zinc air chemical technology, which can be sensitive to the presence or absence of moisture in the air. If you are in an environment that is high in humidity, possibly even wet, hearing aid batteries may absorb moisture through the holes that are designed to take in air to activate it, and subsequently this can shorten battery life.”

If you have spent a number of hours in a high humidity environment, it is recommended that you allow your hearing aid and its batteries to dry out when you are not wearing it. Opening the battery door and leaving it in a cool, dry place will help to remove any condensation or moisture from within the device.

You could also use a hearing aid dehumidifier to help maintain your device.  However, remember to remove the batteries from the device first.  Using a dehumidifier with batteries in situ can unfortunately have an adverse effect on the batteries by drying them out.

The opposite of a high humidity environment is, yes, you guessed it, low humidity, and that can also have an impact on your hearing aid batteries. Paul continues; “If the environment is very dry and hot, such as you’d find in a warm holiday destination, this could cause your hearing aid batteries to dry out much quicker than they normally would, which will also reduce battery lifespan.”

Cold Conditions

Reduced temperatures may lead to a lowering of the hearing aid battery voltage during use as the zinc air reaction can be subdued.  This can, in extremely cold conditions, lead to a premature ‘low battery signal’ from the hearing aid, giving the perception of reduced battery life.  However, the greatest risk to your hearing aid and its batteries in cold environments is of condensation forming within the hearing aid when moving from a cold to a warm environment.

“When the air temperature drops, your hearing aid will also cool down,” says Paul. “If you are outdoors in the cold and then you go inside where the temperature is higher, condensation could form on your device. This can cause moisture damage to the electronics and/or the hearing aid battery.  It is rather like wearing spectacles in winter, moving from an outside cold environment to an inside, warmer atmosphere with more moisture in the air where your lenses sometimes ‘fog’ as warm air meets the cold surface.”

Moisture damage can also occur when your hearing aid comes into contact with rain, snow, or even perspiration from heavy exercise or exertion.

If you are expecting to be in a colder environment for more than a short time, it is recommended you wear a hat, earmuffs or a headband to help protect your ears and hearing aid device. As well as preventing condensation from forming on your device, it can also stop sweat, rain or snow from damaging the hearing aid or the battery.

If you do accidently get your hearing aid damp, you can try using a hearing aid dehumidifier to dry it out, but again, remember to remove the batteries first.

High altitudes

If you live in a place high above sea level or spend time up in the mountains, you may notice a difference to the life of your hearing aid batteries. This is because the percentage of oxygen in the air decreases as altitude increases.

“At high altitude, there is less oxygen in the air, which may cause the battery to reach its endpoint earlier or lead to false low battery signals.” says Paul. “Combined with normally low temperature at mountain-high altitudes, the effects on your hearing device’s batteries could be quite remarkable.”

If you are planning to go somewhere that is of high altitude, it is recommended you take extra hearing aid batteries with you, just in case.

Active Core Plus

Our RAYOVAC® Extra and ProLine hearing aid batteries now contain Active Core Plus™ technology, providing improved cell consistency, longer lasting battery life and increased cell stability. Find out more on our Active Core Plus™ page.

Going to the gym and bodybuilding with hearing loss, by Max Osiris

Massimo Luliano, AKA Max Osiris, is a profoundly deaf bodybuilder from South-East London, UK. In a guest blog post for RAYOVAC, Max discusses his fitness journey and gives us his tips on starting out at the gym as a hard of hearing person.


The beginning of Max’s bodybuilding journey

I started at my very first gym three years ago. At that time, I had quite low confidence but I really wanted to make changes to my body. I was quite skinny, weighing about 82kg.

My friend and I went for one session; I remember thinking at the time; “what if I do something wrong or mishear things, it’s going to be embarrassing”. I was very nervous, to be honest.

As soon as I got in the gym and started some basic workouts that my friend showed me, I noticed that no-one was really looking. Everyone in the gym is usually only focusing on their own fitness journey. A lot of the worries slowly started disappearing as I kept on training for the rest of that session.

After that very first session, the ball started rolling and I was already researching routines and diets online – the more things went on, the more I learned. Bodybuilding is a learning curve; you don’t always have the knowledge about everything, but you can work around it by researching it online and talking to people.


Increased confidence and improved diet – Max’s progress now

Three years later, I’m a much happier person and a lot more satisfied with myself. I have become more confident, outgoing and not afraid to speak my mind. My weight has increased, which is much healthier. I have visited many gyms and learnt a lot from my visits.

I am now a member at a gym in Wallington. The gym has given me a self-discipline that I’ve never really had or developed before. Because of that, it has helped improve my concentration skills as well.

My diet has completely changed too – I opt for healthy protein-orientated meals and plan them weekly. I have also changed my diet to a vegan diet, not only based on how healthy and positive it is for the environment, but also because how my body benefits from it.

I usually prepare my food on the Sunday before the start of the week; this allows me to control what I eat and also makes it easy to grab my food and eat after workouts – it can be hard to fit in cooking when my time is usually taken up by work and bodybuilding.

Max’s tips for starting out in the gym if you have hearing loss

Don’t be afraid to step in

Everyone has to start somewhere! Every single person in the gym was most likely to be nervous when they first started, and they have probably made a few mistakes. No-one is really bothered about new people, and many people I’ve encountered have always been more than happy to help demonstrate or give tips.

Don’t expect results fast

It takes time for the hard work to show, it will develop over time. I was not the size I am now, back then; I certainly wasn’t last year and neither the year before – it is an ongoing process.

Maintain your fitness

When you are seeing results, it’s important to maintain your fitness. Muscles need to be constantly worked and fed correctly with a consistent diet in order to maintain their state. Protein-rich diets are very good for muscle maintenance. There are lots of nutritionists that can help you out; online ones are even better as you can email them – just make sure they hold nutritionist qualifications.

Correct etiquette can go a long way!

Make sure you are wary of your space; use your eyes to look around and ensure you aren’t blocking other people’s views, in the way of areas that people may need to get to, or interrupting workouts. That can irritate a lot of gym users. Always put your equipment back in the same place that you found it, no one likes having to spend time hunting for another matching dumbbell that’s been dumped somewhere else.

Use headphones to block out background noise.

Sometimes gyms can be noisy. It may be people grunting, shouting or loud music blaring out. It may be distracting for you, especially if you’re concentrating on your workout. I suggest using over-the-ear headphones with noise-cancelling and playing a personalised playlist, or turning off your hearing-aids if the noise is that bad (I personally have never had to do the latter).

Headphones have really helped me as I don’t get distracted with voices from different directions. It benefits me even more, as people tap me to get my attention more often when I wear headphones, which really helps!

Always bring extra hearing aid batteries with you.

You never know when your batteries will run out. I always keep a spare pack of Rayovac batteries in my gym bag, which are for emergencies. My batteries have gone flat in the gym many times, and while it didn’t affect my workout, it did make it slightly more difficult to communicate with hearing workout partners.

If you sweat a lot, invest in sweat covers for your hearing-aid.

Too much moisture can damage your hearing-aid; sweat covers stop that moisture getting inside and can also be easy to apply and remove. There are a few available online that can be easily ordered.


I really hope this blog piece has given you more of an insight, and has proven useful. Remember, being deaf makes no difference – anyone can achieve anything, no matter what disability they have.
