[Specifications] Battery disconnect switch rated current: 240A, rated voltage: 12V, standby power consumption: 3mA, power-off threshold: 11.8V±0.2V, instantaneous current: 500A. [Manual and remote control] This disconnect switch can prevent the car battery from being drained due to long-term parking, line aging, and forgetting to turn off the lights. It helps preserve car battery power, providing effective protection and extending battery life. [Smart car disconnect switch 12V] When the battery voltage drops below 11.8V, the remote termination switch automatically cuts off the power after 120 seconds to save energy; when the voltage exceeds 13.5V, the remote control is disabled to prevent accidental power shutdown while driving, and the switch can only be controlled manually. [Automatic cut-off] If the voltage falls below 11.8V, the remote termination switch automatically cuts power after 120 seconds to conserve energy, and if the voltage rises above 13.2V, the remote control is disabled to avoid accidental shutdown during driving, allowing control only via the manual switch. [Protect the Battery] Using this car battery termination switch helps avoid unnecessary power drain caused by long-term parking, malfunctioning electronic equipment, line aging, and forgetting to turn off the lights. It effectively protects and prolongs the life of the car battery.
