Review on Enhanced Autel AL539B OBD2 Scanner: 3-in-1 Code Reader, Battery Tester, Avometer for 12 Volts Batteries, Advanced OBDII Diagnosis and Circuit Starting & Charging Systems Test by Ryan Garrison

Autel AutoLink AL539B OBDII is a really good product, so it's easy for me to test it. Received this specifically for the battery check function plus obdii diagnostics. Well, it worked out great, just like I expected. It came quickly with a sturdy and durable carrying case containing various accessories, a test main line, a test machine, a probe, a battery test lead, a mini USB cable and instructions. Everything is well organized. Car maintenance and repairs have always cost me a lot of money at the garage, but now I think it's a piece of cake since I already have this professional multifunctional diagnostic scanner. Autel AL539B---Obdii code reader with built-in AVOmeter and battery tester. For example, last week the check engine light came on on my Jeep Grand Cherokee. Read codes with this AL539B, get "P0125" Insufficient coolant temperature for closed circuit fuel and "P1155" Heated Oxygen Sensor - Heated Circuit (Bank 2 Sensor 1). Just like someone said "intelligence and knowledge separate men from boys, adjusters from claws", I successfully solved the problems and turned off the check engine light with instructions. I also checked my Jeep's charging and starting system, but they tested as "NORMAL". Accessed the load test interface and the result is "NORMAL" with load voltage: 13.67V, no load voltage: 14.02V. And the starter test told me the cranking condition was read as "NORMAL": Starting voltage: 8th . 85V, percentage voltage: 82%, start-up time 31ms. Well, very easy to use and read accurate data. When it comes to battery test function, AL539B is definitely a professional and reliable tool. And advantages: 1) It has a complete battery analysis system that shows the voltage, good and bad, as well as the power output of the battery with an accurate value; 2) It is equipped with a unique dual battery rating system that can recognize different battery types. standards; 3) It can correctly determine the health status of the battery; and after the test, displays the specific test results: good battery, good battery needs charging, battery needs replacing, bad grid, etc. Also, the screen shows the battery voltage and battery current, so I can clearly understand the specifics of battery conditions. And compared to battery testers without a monitor, this beautifully designed code reader is much more convenient for me to analyze the condition. Definitely happy with this item. Overall it's like 10 tools in 1 and it has everything a person working on basic car maintenance and repair really needs.
