Different Battery Test Result Displayed 1.Green LED ON: Good, the battery is in good condition, you can rest assured of using it; 2.Yellow LED ON: Recharge, it’s a good battery with low current, and please recharge it before next using; 3.Red LED ON: Replace, the battery is almost or already broken, and you need to replace the battery. Cranking Test to Know the State of the Starting System 1. Entering cranking test and starting the engine as prompted, tester will automatically complete the test; 2. The tester will display the result including actual cranking voltage and actual cranking time; 3. If cranking voltage value is lower than 9.6V, the cranking system is regarded as abnormal; 4. If cranking voltage value is higher than 9.6V, the cranking system is OK. Charging Test to Know More about Charging Volt 1. Normal – the generator output is normal, no problem detected; 2. Low – check the drive belt of the generator and the connection between generator and battery, or follow the manufacturer’s suggestion to eliminate generator fault; 3. High – replace the generator assembly or a regulator to avoid battery damages; 4. No Volt Output – check the generator connection cable and the belt; 5. Diode Test – there is at least one diode is damaged if ripple volt is too high. Multiple Languages English, Russian, Spanish, French, Italian, German Review: Not the cheapest, but worth the money - Got this battery tester for my personal vehicle and working on fleet cars, easy to use and useful (especially the printer so I can keep track of tests of multiple vehicles). Seems quite accurate, already used it to identify my car's battery was on the way out and replaced it before the cold weather started and it caused various issues (before it gets to the stage the car even fails to start, the ECU will log error codes and other strange things can happen). Its not the cheapest but well made and like a lot of Topdon stuff is decent value for money Review: repair saver - this product is great if you work on vehicles u no how a good battery is vital to modern day cars functioning i tried a few different repair centres who where telling me my wifes car had injector problems or a slow fuel pump or there wasnt enought pressure from the fuel pump ,but haveing had a start issue with another car that was fixed by a mechanic who had a good battery tester it was the battery though slowly cranking over i wouldnt of thought it was a battery fault he had a similar earlier tester ran it on the battery and a new battery was advised i had it replaced and it starts first time very quickly. i saved hundreds with this battery tester with my daughters car a great price a good piece of equipment for the mechanics tool kit thank you regards gary ## Features - [Car Battery Tester] You can easily test and inspect your 12V lead-acid battery with this TT TOPDON car battery tester.
