The KINGBOLEN BM310 is a 12V Car Battery and Alternator Tester compatible with Cars, SUVs, light trucks, and motorcycles, but not with 24V trucks. It features 6 LED lights (2 red, 3 green, and 1 yellow) to display the battery and alternator status.

The tester's specifications include a maximum voltage and current of 13.9V 15A, a wire length of 25cm, and a size of 12.4 x 5 x 1.8 cm. It can check if the battery is alive and ready to be charged, test the alternator by accelerating the engine to 2000 rpm, and indicate the battery's charging percentage.

The tester's displays provide detailed information: Display 1 (all LEDs off) indicates no charging voltage or a dead battery; Display 2 ("ON" LED blinking, others off) shows 4.1-11.1V charging voltage and a struggling engine; Display 3 ("ON" LED on, "LOW" LED blinking) indicates 11.1-11.5V, a low-charged battery, and the need for immediate charging; Display 4 ("LOW" LED on, "MIDDLE" LED blinking) shows 11.6-12V, a middle-charged battery, and the need for sooner charging; Display 5 ("MIDDLE" LED on, "FULL" LED blinking) indicates 12.1-13V, a middle-charged battery, and the need for charging; Display 6 ("FULL" LED on, "GOOD" LED blinking) shows 13.1-13.9V, a good battery, and a full charge; Display 7 ("GOOD" LED on, "FAULT" LED blinking) indicates 14-15.7V, a potentially damaged battery, and the need to check the engine and tester.

The tester features a special design with copper clips, sensors, and a no-slip grip, making it durable and easy to use, even while wearing gloves. It comes with a 12-month warranty and a 30-day no-reason refund or replacement policy, ensuring a worry-free purchase.
