Features:

 Uses: It can quickly detect the condition of 12V car battery and charging system, and indicate it by the corresponding LED.

 Function: Always monitor the battery voltage and whether the charging system is working normally, so that the battery can be used under normal working voltage, so as to prolong and protect the service life of the battery and the engine.

 Application: Suitable for battery cars, motorcycles, golf carts, 12V batteries for family cars (not suitable for 24V passenger cars, trucks).

 Design: The product is ergonomically designed, with excellent hand feel, easy to use and simple operation.

 Material: The appearance is made of environmentally friendly engineering plastics, and the interior uses a new microcomputer control chip.

 What U Get: 1Pc X Car Battery Tester.

 Specifications:

 Item name: Battery charging system detector

 Model: CNBJ-801

 Item weight: 78g/2.75oz

 Measurement method: Connect the positive (+) pole and negative (-) pole of the car battery to measure the voltage range value of the car battery.

 Measurement range: 2~14.8V

 Voltage display color: Red, yellow, green.

 As vehicle products become more and more abundant, the installation of speakers, refrigerators, vehicle vacuuming, vehicle inflation, vehicle lighting, and electricity for field outings. Motorcyclists refit horns, change headlights, add speakers, and use electric gloves.

 When people are using electricity, they always worry about whether the battery will lose power and whether the car will not be able to start.

 Now you don't have to worry all the time, there is a battery tester that can detect the fluctuation of your car's voltage at any time. Let you have no worries and enjoy playing.

 What kind of voltage is normal: 12V~14.5V.

 If the car is powered on and not started, it is the voltage of the battery. The normal value is 12-12.8V. If it is lower than 11.6V, you should pay attention. Turn off the electrical appliances in the car as soon as possible and start the engine to charge immediately. If the value is lower than 10V, it may not start.

 After the car is started, it is the generator voltage. The normal value is 13.5-14.8V. If it is lower than 13.5V, the battery cannot be charged. Check the abnormal load of the generator belt and the vehicle electrical appliances. If it is higher than 14V, the power generation will be too large and the battery will be damaged. With on-board electrical appliances, check the alternator regulator.

 Note: 

Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 10-30mm.
