Car battery terminal covers

A pair of battery terminal caps to prevent the terminals from being accidentally contacted or even shorted when not in use.

There are two plates with a single positive or negative cover on each as it's intended that they're printed in red plastic for the positive and black plastic for the negative. Note that the posts are of different dimensions.

The caps are designed for DIN A1 battery terminals which are used by the majority of European cars.
