This is the latest 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 (pre 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 AccuMate 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.
