I want to put a trickle charge through my Occy Mark 1 battery but the spanner I need to get to the battery poles has gone walkabouts. Does anyone know the actual spanner size I need to buy please? I'm thinking a 10mm but want to make sure. As always all replies are gratefully appreciated.

10mm and 13mm for the base clamp

There should be the relevant spanner in the toolkit in the spare wheel well.

Thank you posters.
