Battery Health Test

Accurate and speedy. Once you connect this 12V battery tester to battery terminals, you’ll get the readings of CCA values/ratings, voltages, internal resistance, state of health (SOH), and state of charge (SOC) in 3 seconds, with concise results like “GOOD, BAD, REPLACE, or RECHARGE” for quick checkups.

Cranking Test

If your car battery is 4 or more years old, this battery tester helps predict if the battery will fail to start the vehicle.

The TOPDON BT50 digital battery tester will show you the cranking time in milliseconds, and record the lowest voltage that the battery is able to maintain while the starting motor is working.

If the result is < 9 volts, you need a battery replacement.

Charging Test

If you find the engine has difficulty continually running while traveling, switch this battery load tester to the charge testing mode with the vehicle running.

If the battery and alternator are good, the result should be between 14.2~14.5 volts. Lower than this means your alternator or parts of the charging system need to be investigated.

Data Review

This car battery tester gets answers fast. It can automatically record the most recent test result.

This way you’ll easily get the previous data to avoid the retest from the scratch and keep the battery health logs or share the information with others.

4. The BT50 battery tester will power up once it gets connected to the battery you’re testing and is ready to function.

Notice: If the battery voltage is lower than 8V, the BT50 battery tester stops the test and displays a message indicating low voltage. Please charge the battery and test again.

The battery monitor will show you one of the following results in minutes:

  • GOOD BATTERY: The battery is in good condition.
  • GOOD, CHARGING: The battery is good but has a low current; it needs to get recharged.
  • REPLACE: The battery is almost dead, or there is a poor connection between the battery and the tester. Replace the battery or test it again. An out-of-vehicle test is recommended for a second test.
  • RETEST AFTER CHARGING: Fully charge the battery and retest it. If the same reading occurs after the battery is fully charged, replace it.
  • BAD CELL, REPLACE: The battery is broken, interiorly damaged, or has short circuit. Replace the battery.
