Extends the output cable of any Battery Tender® WaveCharge on-board charger bank by 5 feet with a marine-grade cable and connector assembly rated for permanent installation in the harshest marine environments. Where the WaveCharge unit is mounted in an engine compartment, electrical panel, or above-deck enclosure and the battery bank is beyond standard cable reach, the 5ft marine extension provides the additional length needed without compromising the waterproof integrity of the installation.
Marine-Grade Construction
Tinned copper conductors resist corrosion in salt air and marine humidity. Waterproof sealed connectors maintain the system's protection rating in bilge, engine room, and below-deck installations. Built to the same construction standard as the WaveCharge charger line itself for permanent, maintenance-free installation.
