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.
