Figure 5.8.1 SECTION 6 FAQ Q: What types of batteries does the BT20 work on? A: 12V lead-acid batteries. Q: How to determine whether the battery is good or bad? A: The larger the battery capacity, the higher the voltage value of the load test. Generally speaking, the load voltage should be above 10V for batteries above 50Ah (500CCA); above 9.5V for batteries above 20Ah (200CCA). Q: Why does the device get hot after running tests? A: The device tests the battery by simulating the vehicle load. It is normal for the device to heat up. Q: What is the maximum battery capacity supported by BT20? A:
It is not recommended to test batteries with a capacity greater than 200Ah (2000CCA), because their output current is too large and may cause the device to overheat. EN I 22
