Battery Guide V3
HABEX Battery Guide
There are four sizes of hearing aid batteries made by several manufacturers – 675, 312, 13 and 10.
The dimensions of each battery size comply with international design standards. This guide assists people in
identifying the correct battery size and to cross-reference the various manufacturers’ brands.
Actual Battery Size
To assist people with identifying their battery size, the packaging and peal-off tab has been colour coded.
The table below indicates the colour code for each battery size.
Alternatively, print this page out on your printer (without any scaling) and place your battery on the table
below to identify your battery size.
Please take care with Size 312 and Size 13 batteries – the diameter is the same but the height is different and
it is very easy to confuse these two battery sizes.
