OptiMate Monitor Permanent battery lead with integrated battery status / charge system monitor for 12V lead-acid

Weatherproof long battery lead with state of charge monitor for the 12V lead-acid battery in your parked car, pick-up truck, boat or powersport vehicle – 24-7 battery status at a blink of an LED!

• Longer 100cm / 40″ length with M8 / 5/16″″ ringlets that fit a variety of battery terminals, with 15A fuse that protects the -40 rated cable and electronics – Premium quality!
  
• Sealed monitor with 4 LEDs indicate battery state of charge from full to empty for 12V lead-acid (AGM, GEL or STD) batteries – LED corresponding to charge level blinks every 3 seconds.
  
• SAE quick connect charge port for charging battery when needed – With weatherproof sealing cap when vehicle is moving!
  
• Displays charge system status when engine is running – Easy pre-run check at a glance to see if battery is receiving charge.
  
• Smart battery lead that measures voltage; monitors charge of a ‘larger’ stored 12V lead-acid battery and confirms if the vehicle charging system is working correctly.
