Battery master disconnect switch made from zinc alloy with copper plating. Designed to protect your vehicle battery, prevent unauthorized use, and simplify maintenance or long-term storage. Key benefits Prevents battery drain and unauthorized starting by fully disconnecting the battery when the vehicle is idle. Corrosion- and rust-resistant construction extends service life compared with untreated contacts. Copper-plated contact surfaces provide excellent electrical conductivity, reducing voltage distortion and helping preserve battery performance over time. Simple, reliable manual operation: pull the green button to connect power, loosen the green button to disconnect. What it does Isolates the vehicle battery quickly and securely to stop parasitic drains and prevent accidental starts. Provides a safe, manual disconnect for maintenance, repairs, or long-term storage. Important attributes Material: zinc alloy body with copper plating on conductive surfaces for improved durability and conductivity. Corrosion resistance: plated surfaces resist rust and oxidation common in automotive environments. Operation: manual green button control — pull to engage, loosen to disengage — no special tools required for daily use. Compatibility: intended for vehicle battery systems to prevent unwanted battery consumption and unauthorized use. (Refer to your vehicle or installer for fitment and wiring requirements.) How it solves common problems Battery drain during storage or infrequent use: isolates the battery to prevent slow discharge from electronics and accessories. Unauthorized or accidental vehicle starting: physical disconnect prevents starter current flow. Corrosion at terminals: plated contacts reduce corrosion and help maintain good electrical connection and battery health. Typical use scenarios Seasonal storage: disconnect the battery on cars, trucks, or RVs stored for weeks or months to avoid discharge and extend battery life. Maintenance and repairs: quickly isolate the battery to work safely on electrical systems without removing the battery. Fleet or off-road vehicles: prevent unauthorized vehicle use when parked for long shifts or between assignments. Simple installation and use Designed for straightforward installation in the vehicle’s battery circuit; follow vehicle-specific wiring guidelines or have a professional install. Daily operation is manual and intuitive: pull the green button to enable power and loosen it to cut power. Durable, practical, and easy to use — a reliable solution for protecting vehicle batteries and simplifying safety, maintenance, and storage.
