This is the TM version of the fused permanent connection lead - our most popular accessory. 
This version of the fused eyelet lead is the same format as those supplied with OptiMate (1999-2012) and AccuMate (pre 2015).  It has a rubber cover for the 2-pin connector to keep the electrical connects dry and corrosion free.
You can use additional leads to fit one to every vehicle which requires its battery to be charged - in this way one OptiMate or can be used with several vehicles on a rotational basis very simply and quickly.
Simply connect the 2 ring terminals to your battery and the weatherproof 2-pin connector will always be available to connect to your OptiMate, AccuMate, or power accessory without having to delve into the vehicle.

Optimate lead
A decent no fuss lead, this replaces an old one. With attachments it's pretty versatile on the bike, as well as hooking up to maintain the battery when required.

Battery charger connector
Left my connector on a bike when I sold it, the new optimates have a different style connector now, so I was so impressed that you could still buy the old one
