This is a high-quality fully functional battery charger lead supplied by Optimate UK. 

This is not cheap imported rubbish this is from my Optimate 4 charger and I do not require it.

The lead has been tested and is fully functional.

The lead is fitted with a 7.5A fuse.

The charger lead is suitable for all lead-acid batteries and has a voltage of 12V. 

It has an amperage of 7.5A and is designed to charge your battery to its full capacity. 

The rubber boot on the connector has a small hole (see photograph).  The rubber boot can be removed from the lead if required.
