Car Battery Disconnect Switch Isolator

Battery Isolator Switch – 12V 240A Wireless Remote Control Disconnect for Cars, RVs and Boats

Keep your vehicle battery protected and secure with this intelligent Battery Isolator Switch, offering wireless remote control disconnection, automatic voltage protection, and ultra-low standby power consumption. Compatible with cars, RVs, boats, and light commercial vehicles with engines under 4.0L, this battery isolator switch prevents parasitic drain, guards against deep discharge, and adds a practical layer of anti-theft security without requiring access to the engine bay.

Product Features

• Wireless Remote Control with Two Remotes: Disconnect and reconnect your battery from a distance using one of the two included remotes, making this battery isolator switch a convenient daily-use solution for vehicle security and battery management.
• Automatic Cut-Off at 11.9V: This battery isolator switch automatically disconnects power when voltage drops below 11.9V (±0.2V), protecting the battery from deep discharge during extended periods of inactivity.
• 180-Second Inactivity Timer: If no activity is detected, this battery isolator switch cuts power within 180 seconds, preventing unnecessary battery drain and improving overall energy efficiency.
• Driving Safety Lock at 13.2V: When alternator charging voltage exceeds 13.2V, the battery isolator switch locks to prevent accidental shutdown while the engine is running, ensuring safe and uninterrupted vehicle operation.
• 3mA Ultra-Low Standby Current: The control module of this battery isolator switch draws only 3mA in standby mode, consuming virtually no power when the system is idle.
• 500A Surge Current Handling: Built to manage surge currents up to 500A, this battery isolator switch reliably supports high-demand engine start loads across a variety of vehicle types and conditions.
• Copper Wiring and Built-In Leakage Indicator: Heavy-duty copper wiring ensures strong, stable conductivity, while the integrated leakage indicator panel helps identify electrical faults quickly and without specialist tools.
• Rated for -30°C to 90°C Operating Range: This battery isolator switch is built to perform in extreme temperatures, making it suitable for year-round use in cold winters and hot summer climates alike.
