Look at the voltage value of the display to determine whether the battery is good or bad

Test DC12V battery:

Good condition: the 12 Volt charging system test is greater than 13V, and the battery is in good condition.

Normal: the 12V charging system test is between 9V-13V, the battery status is normal.

Defective or need to be charged: the 12 Volt charging system test is less than 9V under load, and the battery status is unqualified.

Test DC6V battery:

Good condition: When the display voltage is greater than 7V, it means the battery is in good condition.

Normal: When the display voltage is between 4.6V-7V, it means the battery is normal.

Defective or need to be charged: When the display voltage is low than 4.6V, and the battery status is unqualified.

This battery load tester is to provide with reference advice, these value ranges are not absolute, should depend on the battery situation(Battery usage time and whether is full charged test, etc.) Some batteries that are not fully charged, or used for a longer period of time, will be a little low on voltage under load and it is normal. It is enough for daily use to test battery and determine good or bad battery condition.

Note

When it is used, the coil will be hot and red, due to the protective coating, the first use may have an odor or smoke, this is normal.

Testing the health of the battery, state of charge. This battery tester can test batteries for cars, motorbikes, trucks, RVs, ATVs, SUVs, boats, yachts, lawnmowers, etc.
