Car Battery Alternator Tester

CARTMAN is a brand that was founded with the idea of providing high-quality, durable, and affordable tools to both professionals and DIY enthusiasts. The story of CARTMAN began in 2013 when a group of experienced tool designers and engineers came together with the goal of creating a brand that is of quality and innovation, and also affordable. At CARTMAN, we believed that everyone should have access to the right tools to get the job done, no matter their skill level or budget. We have always adhered to our original mission of providing customers with high-quality products that are both affordable and reliable.

The team at CARTMAN worked closely with experts in various industries to ensure that each tool would meet the highest standards of performance and durability. Over the years, CARTMAN has continued to expand its product line, adding new tools and accessories to meet the changing needs of its customers.

This is a great little affordable gadget, a handy tool to check batteries and alternators. It is only compatible with 12V vehicles, such as cars, SUVs, and motorcycles, as well as light trucks. The shell is designed in one piece, which is not easy to rust and lasts for a long time. The ergonomic design provides a comfortable hand feeling, making it convenient and simple to use, and it is not expensive.

The product features solid clips, a screwless design, and battery monitoring capabilities. To use it, simply connect the test clips to the battery's positive and negative positions, and the LED display will indicate the car battery's condition. The green light lit when accelerating the engine to 2000 rpm means the charging circuit is okay, while the red light shining means the dynamo supplies no or very little voltage.

The LED display also indicates the percentage of charge in the battery, whether it's full, middle, or low. Additionally, the red light indicates if the voltage from the alternator is over-high during cranking. This device does not support 24V trucks, but it is compatible with hybrid electric cars.

The product specifications include 6 LED lights (2 red, 3 green, and 1 yellow), 0.06 square millimeter copper wire material, a maximum voltage and current of 13.9V 15A, and a wire length of 9.84 inches. It can be used to check the alternator state, battery state, and for pre-charge checks, as well as to detect overloads.
