Introduction

Rather than lifting the bonnet and removing the battery cover, vehicles can be charged using the tow electric socket, if you have either twin 12N/S electrics (with two 7 pin sockets) or the 13 pin socket.

The wiring between the 12V positive pin below and the battery is fused on the vehicle but it is recommended to add an additional fuse in your electrics wiring for maximum safety. Choose a fuse with a rating a little over the maximum output of your charger.
