Specification Brand : Reland Sun BulletPoint1 : This is a DIY kits,need buyer to assemble it. BulletPoint10 : ❤【Attention】As a professional auto battery repair tool, it is recommended to be operated by a professional auto mechanic to avoid irreversible damage to the parts or car due to misoperation. BulletPoint2 : Power display is to take some voltage, perform simulations show the percentage of segments, such as 3.7V lithium battery, take the lower voltage 3V, the upper limit of 4.2V, 4.2-3 = 1.2V, the voltage difference between the lower limit of 1.2V, is the battery Analog power up. BulletPoint3 : LM3914 can accurately detect an analog voltage, 10 LED display, either Multi-light bar display or a single light dot display. BulletPoint4 : 10 LED Displays the battery voltage,bar display full brightness 42mA, single light shows 4mA. BulletPoint5 : Support: single lithium 1S (4.2V) ~ 4S (16.8V), lead acid 6V ~ 12V, NiMH 3.6V ~ 18V, nickel-cadmium batteries 3.6V ~ 18V. BulletPoint6 : ❤【Easy to Use】The car battery charging detector can quickly detect the condition of the 12V car battery and charging system, and supports the detection of 2-14.8V battery and charging system output (<14.8V) and is indicated by the corresponding LED. BulletPoint7 : ❤【Plug and Check】This tester supports testing the battery when there is no electricity. It does not need to be fully charged before the test. The test result is simulated by a color-coded voltmeter, which is easy to read. BulletPoint8 : ❤【Good Performance】The factory has set up strict product production quality standards, so that you can easily and directly detect bad batteries, even if it is reversed, it will not damage the tester or affect the vehicle and battery. It is professionally manufactured and has high reliability. BulletPoint9 : ❤【Widely Used】It is Suitable For all vehicles with 12V battery such as motorcycles, cars, campers, etc. It can be placed in the trunk or other storage space. It is Suitable For vehicle maintenance and maintenance. It is a high-quality maintenance and repair tool for all types of vehicles.
