Optimized Battery & Charge System Monitor for 12V Lead-Acid

This versatile 12V battery charge monitor and charging system tester is compatible with any 21mm AUTO power socket. It features a multi-function LED display that indicates the battery's state of charge, as well as the vehicle's charging system status.

The battery charge level is signaled by an LED that blinks every 5 seconds, corresponding to the charge level. A fast blink mode activates for the first 15 seconds after connecting to the battery, making it ideal for testing multiple batteries, such as those in a showroom.

The vehicle's charging system is monitored as well. When the charge voltage reaches the minimum threshold of 13.5V, a green LED will illuminate. If the voltage reaches the ideal range of 14V or above, a brighter green LED will light up, confirming the charging system is functioning properly.

This adapter seamlessly plugs into any standard 12V power port (7/8" or 21-22mm) that remains live even with the ignition off. It features an integrated 10A fuse to protect the connected electronics. The sealed monitor has 4 LEDs that indicate the battery's state of charge, from full to empty, for 12V lead-acid (AGM, GEL, or standard) batteries.

A weatherproof, hinged cap covers the SAE quick connect charge port, allowing you to charge the battery when needed, without exposing the port while the vehicle is in motion. The charging system status is displayed when the engine is running, providing a convenient pre-trip check to ensure the battery is receiving the proper charge.

This versatile tool is an indispensable accessory for motorcycles, ATVs, cars, pickup trucks, and boats, allowing you to monitor the health of your 12V battery and quickly diagnose any issues with the vehicle's charging system. Its compact design and universal compatibility make it a must-have for any automotive enthusiast or professional.
