Hearing aid batteries
Why is there a sticker on the back of each battery?
Modern hearing aid batteries are activated by air which enters the battery through small holes in the back of the battery. To stop them from working too soon, the holes are covered with a coloured sticker. When removed, the air can get in and start the battery operating.
Why are the stickers on the batteries different colours?
To make identification of the batteries easier, all batteries have a coloured sticker that depends on the size:
- 675 = Blue tab
- 13 = Orange tab
- 312 = Brown tab
- 10 = Yellow tab
- 5 = Red tab
What should I do with dead batteries?
The clinic where the aids were issued will tell you how to dispose of them. Sometimes they may have a battery recycling collection box or you might find one of these in a local shop or supermarket or council recycling centre – do not just throw away the batteries with normal rubbish.
Keep used batteries away from children and animals as they are dangerous if eaten. If this happens, treat it as an emergency and seek immediate medical assistance.
Can I use other batteries like watch batteries in my hearing aid?
No, hearing aids require a specific battery power to work properly. Others may look the same or be the same size as the proper batteries, but will not give the same power or last as long.
Why does my battery not last as long as my friend’s battery?
Every hearing aid is set-up individually for your hearing loss and will consume a unique amount of power. Your friend may have the same model of hearing aid but it will be adjusted differently. If your aid has a volume control, the battery use will depend on the volume setting you use.
What should I do if the battery gets stuck in the hearing aid?
Do not attempt to remove it yourself or you may damage the hearing aid. Contact your Audiologist for help or advice.
A concerned Hearing Link volunteer sent in an article about a fire at a property caused by batteries touching each and creating a spark. He was concerned about storage of hearing aid batteries.
Hearing Link advice is as follows: ‘Hearing aid batteries carry a fire risk as they can ‘short’ when in contact with other batteries. To prevent this, consider placing used hearing aid batteries back into the original packet (minus the tab) or wrapped in sellotape to avoid interaction.
Also make use of shop recycling facilities as it is now routine for any vendor which sells batteries to have to offer a recycling pot in their premises.’
Hearing Link contacted VARTA Microbattery about this issue. Their statement is below:
‘Responsibility towards the environment plays an essential role throughout the entire life cycle of VARTA Microbattery products. We have set high standards for environmentally friendly development and manufacturing processes, especially for our power one hearing aid batteries.
Therefore, please support our efforts to protect the environment and do not throw away used batteries with household waste. Please deposit used portable batteries in recycling containers or return them at your retailer.
Used zinc air hearing aid batteries can also be brought back to your audiologist. Choosing this way you can trust that your empty batteries will be taken care of properly.
Please also return rechargeable batteries e.g. those ones for cellular phones or digital cameras to the dedicated places. In case you are not sure the rechargeable battery is fully discharged, please mask the battery poles, for example with an adhesive tape.
The same applies to lithium batteries such as batteries for analogue photo cameras (e.g. CR 123A) or electronic equipment (e.g. CR 2032). This procedure helps to prevent short circuits and avoid unexpected situations. For zinc air hearing aid batteries, no special procedure is required.’
