DC 12V Car Battery Disconnect Switch 260A with Remote
DC 12V Car Battery Disconnect Switch – 260A Automatic with Remote Control
Keep your vehicle's battery in top condition with this intelligent DC 12V Car Battery Disconnect Switch. Rated at 260A passing current, this automatic remote-controlled cut-off switch is engineered to protect your car, truck, RV, bus, or trailer battery from unwanted drainage during extended parking periods — so your vehicle is always ready to go when you are.
Key Features
- Magnetic Lock Technology: Uses an innovative magnetic relay system to precisely control circuit connection and disconnection. With an ultra-low standby current of just 0.015A, it delivers outstanding energy efficiency and smarter vehicle power management.
- Intelligent Automatic Disconnection: If battery voltage drops below 11.8V, the switch automatically cuts off power within 120 seconds to conserve energy. When voltage exceeds 13.2V (engine running), the remote is disabled to prevent accidental disconnection while driving — safety first.
- Broad Vehicle Compatibility: Designed for 12V DC vehicles with engine displacement under 3.0L, including most cars, SUVs, trucks, RVs, buses, and trailers. One switch, wide-ranging protection.
- Easy Installation: Connects directly to the battery's negative terminal. No complex wiring required — simply turn off your engine before installation and you're set up in minutes.
- Extended Battery Life: Prevents unnecessary battery drain caused by prolonged parking, aging wiring, parasitic electronic draw, or accidentally leaving lights on. Protect your investment and extend the lifespan of your vehicle's entire electrical system.

Frequently Asked Questions
Q: What vehicles is this DC 12V Car Battery Disconnect Switch compatible with?
A: This 260A battery disconnect switch is compatible with a wide range of 12V DC vehicles, including most cars, SUVs, trucks, RVs, buses, and trailers with an engine displacement of less than 3.0L. It is not suitable for 24V systems or high-displacement commercial engines.
Q: How does the automatic disconnection feature work on this battery disconnect switch?
A: The intelligent automatic disconnection feature monitors your battery voltage continuously. If the voltage falls below 11.8V — indicating a low or draining battery — the switch automatically cuts off power within 120 seconds to preserve remaining charge. Once you start the engine and voltage rises above 13.2V, the remote control is automatically disabled to prevent accidental disconnection while driving, ensuring safe operation at all times.
Q: How do I install this 12V battery cut-off switch?
A: Installation is straightforward. Always turn off your vehicle's engine before beginning. Connect the switch directly to the battery's negative terminal following the included instructions. No advanced wiring knowledge is needed. The unit is designed for a quick, secure fit to ensure stable, long-term performance.
Q: Will this battery disconnect switch drain my battery when on standby?
A: No. The switch operates at an extremely low standby current of just 0.015A, making it highly energy-efficient. It is specifically designed to protect your battery from drain rather than contribute to it, making it ideal for vehicles parked for extended periods.
