Voltmeter with LCD Display & LED Indication It provides a quick reading to determine if a vehicle battery needs a jump or replacing and also the alternator output status. Various Colored LEDs indicate the battery or the alternator status, while the LCD digital screen give the accurate reading of the voltage simutaneously. Compact design & Light Weight Plug & Go - Rubber Paint Housing High Accuracy - Four-character lighted digital display, accuracy close to 0.01volt Reverse-hookup and Over-Voltage protection 50cm/20 inches extension cable with 30Amp alligator clamps Product Features 4-Digit LCD Display The accuracy can be 0.01volt with the 4-digit LCD display screen. 8-LED Indication 8 color LED indication for the battery or the alternator status. Rubber Finish Body Rubber paint on the surface for comfortable hand feel. Alligator Clamps Operation Steps Trouble Shooting Guide - a) - Why does the LCD screen not turn on when connectting the battery tester with batteries? Check if any connection loose on the battery clamps with the battery posts. Check if the polarity connection is reversed. Make sure the red clamp with the positive post and the black clamp with the negative post. b) - The LCD screen does not display correct value. The battery tester test range is 4-20volts DC. If the battery voltage is under 4volts DC, the LCD screen will display "LO". If the battery voltage is higher than 20volts DC, the LCD screen will display "HI". c) - The LED indicators for the alternators side do not turn on but only the LED indicators for the battery side turn on when testing the alternator output. Please start the engine when testing the alternator output. If the alternator output is under 13.6volts DC, the LED indicators for the alternators will not turn on. (It means the alternator output is lower than normal. Check if any problem with the alternator.) d) - The value on the LCD screen is flucturant. The battery tester has no batteries inside. It's powered by the battery to be tested directly. If the battery under testing is weak, the value on the LCD screen may be flucturant. e) - The LCD screen does not turn on but only the Red reverse LED turn on. The connection with the battery should be reversed. Please correct the connection to operate again. Review: Good Value - Easy to use. Works great Review: Simple and understandable. - Good tool.

WITH ENGINE ON IT SHOWS BOTH BATTERY AND ALTERNATOR CONDITION. **Q: Does it come with batteries included?** A: It powers up off the battery being tested. No batteries needed. **Q: Why didnt mine come with directions** A: I don't know why. But just connect to battery, read the voltage, go to the charts which tell % charge as a function of voltage-then you know status of the battery. I purchased a second one, put on long wires so I can see if my alternator is charging as I go down the road. Unbelievably accurate for the cheap price. Strong recommendation Jay **Q: With my engine running I get voltage indicated and lights on the battery side of the unit. No lights on the alternator side. Is the unit defective?** A: I'm not a mechanic, but all I do is first I check the voltage of the battery without having started the vehicle. Next I start the engine and check the battery voltage while the engine is idling. While the engine is idling I usually show about 13.8 volts on the tester. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Value *by J***C on April 12, 2026* Easy to use.
