TecMate OptiMate O-11 Fused Weatherproof SAE Battery Lead (5/16"-3/8" Rings)

The OptiMate O-11 is the heavy duty version of OptiMate's permanent battery lead, made for bigger batteries. Its ring terminals default to 5/16" (M8) and adapt to 3/8" (M10), so it fits the round-post clamps and built-in bolt terminals found on car, truck, marine and some large powersport batteries.

Once it's installed, your charger plugs into the weather-sealed SAE connector in seconds. Thicker 16 AWG cable is rated for 10 Amps continuous, a 15 Amp fuse protects the lead, and the cable stays flexible down to -40°F.
