At time of order, the lead can be made 10M long instead of 5M standard.
The price is additional to the standard brand kit.
A thought here if you need a longer than 5M lead, an option is to buy an additional 5M but have battery clips on both ends. This allows it to be used as an extension. It also gives the option of using this extension as a quality jumper lead for starting cars. See item 662.1, 5M Jumper lead.
