Review: Must-Have Car Battery Tester – Easy to Use, instructions provided in review - Amazing for the price. You won’t be disappointed! Works straight out of the box, with no batteries or charging needed since it’s powered directly from the car. The instructions aren’t the best, so for those who might not know: connect it to the car by attaching the Positive (red) clamp to the positive terminal of the car battery first, then connect the Negative (black) clamp to the negative terminal on the battery. It can test batteries both in and out of the car. The device will power on once connected, and you get three options for testing the battery with step-by-step instructions. The three options are Battery Test, Cranking Test, and Charging Test. The Battery Test will determine the health of a battery, the Cranking Test will measure the battery's ability to start the engine, and the Charging Test will measure the voltage of the battery while the vehicle is running to determine if the battery and alternator are working. If you think you have a bad alternator, use this device first and run through the tests. It provides straightforward results (as shown in the photo) that tell you if the battery is good, needs to be replaced, or if the alternator has no output. Couldn’t recommend this device enough
Review: Great tool for mechanics. - I use it every day to test automotive batteries. It’s really easy to use and helps me diagnose problems with the ignition system. It tests, the batteries, the alternator, and the starter with ease.

### ⭐⭐⭐⭐⭐ Great tool for mechanics.

### ⭐⭐⭐⭐ Good tester, but instruction not clear about surface charge
*by D***K on May 24, 2022*

This is a good battery system tester for the money. But the issue of surface charge is confusing and misleading. Even with battery left overnight where surface charge has been dissipated, the tester still indicates that surface charge has been detected and asks the user to turn on headlight for 10 seconds and to continue the testing procedure. The problems with these surface charge misleading instructions are: 1. With battery left without use for more than 6 hours and attained its resting voltage, testing should proceed without turning headlights or other electrical loads on. The tester will give an accurate assessment of the battery condition. 2. With battery at its resting voltage and then turning the headlight for 10 seconds as tester prompts the user, and to immidiatly proceed to testing the battery, the battery voltage will be noticeabley lower than the resting voltage. The tester will alwasy show a much lower state of cahrge, SOC, than the actual SOC. 3. Tester should not say that surface charge has been detected when battery is at ite resting voltage, but it does. 4. Instructions should indicate to user that if battery has been left unused for more than 6 hours to ignore the surface charge prompt and to continue testing. 5. Instruction should also say to user to wait for anout 15 minutes after turing on and off the headlights before procededing to continue testing. Otherwise, SOC reading will be lower than actual SOC. Regards.
