Turn a problem into a leisurely convenience feature when you use ProMariner Marine-Battery Charger DC Cable Extender.

The universal design accommodates all marine chargers with ring-terminal cables. ProMariner Marine-Battery Charger DC Cable Extenders support up to 30A, and sport color-coding for quick and easy installation. The waterproof, dual inline fuses stand up to harsh marine conditions, and the slide-and-snap fully insulated connection covers make usage even easier.
