Test range: 20-3000A. GB - China National Standard. Test range: 3~220 AH. Battery test Battery testing results are accurate and fast. After connecting this tester to the car battery, you will get readings of CCA value/rating, voltage, internal resistance, state of health (SOH) and state of charge (SOC) in less than 3 seconds and get concise results such as "good, bad, replace or charge" for quick check and diagnosis of battery health. Cranking test--Lively monitoring of battery working voltage Provided your car battery has been in use for 4 years or more, this battery tester helps determine if the battery will fail to start the engine.

The BT660 displays the cranking time in milliseconds and records the minimum voltage that the battery can maintain while the starter motor is operating. If the test result is less than 9.6V, the battery needs to be replaced. It gives you a solution to the problem of unexpectedly running out of battery life. Charging test If you find difficulty in running the engine continuously while driving, please switch to the charging test mode with this tester.

If the battery and alternator are good, the result should be between 14.2V and 14.5V. However, if it falls below this value it means that your alternator or charging system components need to be examined. Data review for easy comparison and query This car battery tester provides quick access to test results as well as automatic recording and storage of test results from recent tests. By doing so, it is easy for you to access previous data.

It is convenient to keep the battery health log or share the information with others, which is a good helper for data recording. Built-in printer Designed with a built-in thermal printer. Diagnostic results and test data can be printed on thermal paper. Compared with other printers, thermal printers are simple and efficient to use, which greatly facilitates business needs of users. Simple design& Easy to use Five-key keypad design avoids complicated operations and is simple to use for quick and easy guidance.

The large backlit 2.4-inch LCD displays clear data and is easy to read, even in direct sunlight.
