Low Voltage Detection Alert Car Battery Monitor

After 2-3 years of use, car batteries often experience a slow and gradual drain due to things like playing music or powering other devices after the engine is turned off. the car owner might not even notice. then, suddenly, the battery dies, often within 30 minutes to an hour, leaving the car unstartable. calling for roadside assistance can be both time-consuming and costly We're now launching a battery monitor alarm that detects your battery's power level. it can be plugged directly into your cigarette lighter socket or connected to your fuse box. this device continuously monitors your battery's voltage. when the battery is low and starting becomes difficult, it will sound an immediate "beep-beep" alarm when the voltage drops below 11.3v (adjustable to other parameters). this alerts the driver to start the car and recharge the battery promptly, preventing the frustrating issue of a dead battery and inability to start the vehicle!
