What size batteries are available?
There are four main sizes of batteries that are colour-coded and numbered for use with hearing aids. However manufacturers have committed to producing an even smaller Hearing Aid Battery. While still retaining the same power as before. Ensuring your Hearing Aids are there, for your hearing and not on display.
First size is Blue 675.
This is the largest hearing aid battery available. It can output the greatest amount of power and it used in power heavy hearing aids. Its lifespan is between 3-10 days. Depending entirely on usage, and the conditions it is expected to perform under.
The next size is the Orange 13.
It is one of the more common sizes, as it is used in the smaller behind-the-ear hearing aids. It also used in larger in-the-ear hearing aids, due to both its power and it’s easy handling for users.
It’s probably the most used battery size by the older population, partly due to versatility as well as worldwide reputation.
The life span is roughly 7-10 days depending on the technology in the hearing aid. This affects how much power is needed. However recent developments show that the next generation of these batteries will last even longer.
The third is the Brown 312.
It has the same circumference as the 13, but half the depth. So it is a little fiddlier to use for the older clients. However if you think this means you are getting less for your money think again.
This is quite a common size as it suits the smaller neater behind-the-ear hearing aids. It also covers the smaller in-the-ear hearing aids.
The lifespan for this type of hearing aid battery is about 5-7 days. This depends on power usage from your hearing aid, giving you a similar lifespan as the orange 13 – with the additional bonus of being a smaller size.
Yellow size 10.
The smallest battery (except size 5, but this has been removed in the last few years).
These are for in-the-canal hearing aids. They are nearly completely invisible in the ‘canal’ type hearing aids, giving the bonus of a long lifespan, as well as a smaller size than even the brown 312 can achieve.
How long do hearing aid batteries last?
Hearing aid batteries last between 5 – 10 days depending on the size of the battery:
– Blue Size 675: 7 – 10 days
– Orange Size 13: 7 – 10 days
– Brown Size 312: 5 – 7 days
– Yellow Size 10: 7 – 10 days
Hearing aid batteries usually follow a standard template. The use of materials such as Zinc ensures they are safe to use. Primarily they are made using zinc air technology. They work by oxidising the zinc within the hearing aid battery, with oxygen found naturally in the air
Hearing aid batteries come with a peel off back, which can be seen clearly the moment you remove the battery from the packaging. Once removed, just place the battery carefully in the hearing aid.
The actual make of the batteries are ‘zinc air’ and they come with a peel off back. You need to remove this and ideally allow to sit for a minute before using in the hearing aid. This ‘minute’ allows the batteries oxygen reserve to completely fill before being used and can extend the life of the battery.
Hearing aid batteries can be vulnerable to extreme conditions. They ideally need to be stored at room temperature whenever possible. This ensures their quality is maintained maximising their lifespan. Try to avoid areas that are damp or vary greatly in temperature.
Rechargeable Hearing Aid Batteries
The introduction of rechargeable hearing aids has had a drastic effect on hearing aids worldwide. Thanks to its rechargeable nature, you no longer need to keep a stockpile of batteries for your hearing aids. Although the upfront costs are greater, you end up saving more over the long term.
Hearing aid accessories offers a wide selection of rechargeable hearing aid batteries to suit any brand of hearing aid. Including Phonak, Resound and Widex to name but a few.
How do rechargeable hearing aid batteries work?
The majority of our hearing aid batteries are based on Li-ion (Lithium Ion Battery) technology. They work like other similar batteries by using Lithium Ions in the electrochemistry process. In simple terms they are able to carry a lot of power and store it for long periods of time. There is very little energy loss making them extremely efficient to the point they are used in electric cars.
- However this is being phased out thanks to advancements in power to size ratio for the batteries.
- By decreasing their size while still retaining their power level, you can now have them built permanently inside the hearing aid itself.
What is the advantage of having the battery inside the hearing aid?
By having the battery permanently inside the hearing aid, it allows you to bypass the issue of water damage normally associated with hearing aid batteries. They also remove the need for you to understand how to remove/insert them into your hearing aid.
The ingress protection is quite important for hearing aids and most are at IP68 level these days.
Please check before you purchase the hearing aids you like and ensure it is no lower than this level. If you do not do this you may find you have continual break downs. Especially if you perspire a lot, or live in a humid country. To get around this problem hearing aid accessories allows you to purchase specialised drying units.
This is available for both your hearing aids and their batteries. Not only do they extend the lifespan of your hearing aids. They also give you a secure place to put them at night, preventing damage they might sustain otherwise.
