HT2018B(C) Battery System Tester 15
This product measurement method: Because the battery is actually equivalent to an
active resistance, so we apply a fixed frequency and a fixed current (small current) to the
battery, and then sample its voltage, after rectification, filtering and a series of processing,
finally calculate the internal resistance value of the battery through the arithmetic circuit.
The advantages and disadvantages of this method:
1) Using this measurement method can measure almost all batteries, including small
capacity batteries. The internal resistance of notebook batteries is measured by this
method.
2) Measuring with this method will not cause much damage to the battery itself.
