12V Car Battery Cutoff Switch with LED Display and Wireless Remote Control
Keep your 12V electrical system safe and battery-ready with the 12V Car Battery Cutoff Switch with LED Display and Wireless Remote Control. This intelligent switch minimizes parasitic drain with a standing current of just 3 mA, so your battery stays healthier when the vehicle sits idle. The built-in LED display continuously monitors battery voltage, giving you real-time visibility and helping you act before a battery problemstrikes. The magnetic lock relay provides reliable circuit disconnection, delivering quiet, dependable protection for your battery and connected electronics.
Designed for 12V DC vehicles, this cutoff switch is ideal for cars, trucks, RVs, and trailers (recommended for engines under 2.0L). It offers convenient remote control within 20–30 meters, while also ensuring safety when driving by disabling remote control above 13.2V—preventing accidental disconnections. If voltage drops below 11.8V, the system automatically disconnects after 120 seconds to conserve power. For adding an extra layer of security, the switch can also be operated directly via the switch button if needed.
Easy to install with a negative-ground configuration, it delivers stable performance once wired correctly. Remember to disconnect power before installation to avoid shorts. This device helps prevent battery drain during long-term parking, protects sensitive electronics, and can extend the life of your battery by reducing unnecessary consumption.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
