Here in the UK we have four sizes of hearing aid batteries widely used, they are colour coded and also have a number code that runs independently of manufacturer.

The different sizes are as follows;

675 batteries are the largest size of battery and generally have a colour code of blue. This usually means blue colouring on the packet, often a blue tab (not always, varies from manufacturer to manufacturer, and the number 675 somewhere in the title of the product. An example would be Rayovac 675AE or Duracell DA675. This size of battery is generally used with super power BTE hearing aids.

13 batteries are the next size of battery and generally have a colour code of orange. This usually means orange colouring on the packet, often an orange tab (not always, varies from manufacturer to manufacturer, and the number 13 somewhere in the title of the product. An example would be Power One P13 or Zenipower A13. This size of battery is generally used with most BTE hearing aids and most full shell ITE hearing aids.

312 batteries are the next size of battery and generally have a colour code of brown. This usually means brown colouring on the packet, often a brown tab (not always, varies from manufacturer to manufacturer, and the number 312 somewhere in the title of the product. An example would be Rayovac 312AE or Duracell DA312. This size of battery is generally used with a lot of RIC / RITE hearing aids and most half shell / canal ITC hearing aids.

10 batteries are the smallest size of battery and generally have a colour code of yellow. This usually means yellow colouring on the packet, often a yellow tab (not always, varies from manufacturer to manufacturer, and the number 10 somewhere in the title of the product.

Our sister site Hearing Aid Batteries is a great place to buy hearing aid batteries and all other accessories at very low prices with a very high level of customer care.

Hearing aids need hearing aid batteries in just the same way that a motor car needs petrol to run it. Hearing aid batteries are cell type, similar to a watch battery.

There are 5 types of hearing aid battery available that conform to international standards of size etc, these are 675, 13, 312, 10 and 5. Size 5 is no longer in common use and 675 is only used for ultra power ‘behind the ear’ (BTE) hearing aids, this is becoming less common as more high powered hearing aids now run on the more common size 13 battery.

Most hearing aid batteries at this time tend to be the zinc-air variety, many years ago the standard was mercury batteries but due to environmental concerns this type of hearing aid battery was phased out 15-10 years ago, although there is a small amount of mercury even in the zinc-air batteries.

New developments in hearing aid battery technology are totally mercury free batteries, both market leaders Rayovac and Duracell have products in the market to cater for the environmentally friendly.

At present mercury free hearing aid batteries are at a premium cost wise, but as the technology matures the price difference is likely to narrow.

We recommend our sister website www.hearing-aid-batteries.org.uk for low prices of the leading brands of hearing aid batteries, Rayovac and Duracell, the site also sells most other hearing aid accessories you could need, such as wax traps, domes, cleaning utensils etc etc.

One of the difficulties people find when their hearing starts to deteriorate is that it can become more difficult to converse on the telephone. Up until fairly recently corded landline telephones were the only real option as cordless phones and particularly mobile phones just didn’t have the volume in reserve, which made things pretty difficult for some people.

Good news! In the last year or so there has been a plethora of products launched by various manufacturers to satisfy the needs of the hard of hearing public. On our sister website Hearing Aid Batteries we stock a number of assistive devices suitable for speaking on a telephone, our preferred manufacture is the renowned Amplicom.

We stock a couple of mobile phones that really pack a punch in the volume department. We stock corded and cordless phones (including bundles of cordless phones that you can place in various parts of the house), also optical ring flashers to give you a visual warning the phone is ringing and vibration shaker alarms which you can place under your pillow. (Handy to make sure you don’t miss important calls when you take your hearing aids out at night!).

All the devices have plenty of amplification and are compatible and suitable for hearing aid wearers.  Don’t be shy and pop over to the site and take a look.
