FAQ for Battery Analyzer

Q: What is the difference among impedance, internal resistance and conductance measurement?
A: Impedance and internal resistance are using different method of measurement. Impedance testing is generally injecting a current signal to battery so as to measure its resistance. This is proved to be unstable and inconsistent measurement when UPS batteries are in live condition.

Internal resistance measurement is generally using DC or AC signal discharge to measurement internal resistance and voltage of cell.
Conductance (unit: Simens) measurement is same as that of internal resistance (unit: Ohm). Their relationship is: S=1/R. All Kongter’s battery testers are switchable between resistance and conductance measurement. They are using measurement method of discharging a low current AC signal. Customers with different measurement habits can find their right solutions.

Q: Do you use alligator testing clamp or pin probe for measurement of batteries?
A: Kongter offer both alligator testing clamp and pin probe for different types of batteries. User can select either as per their need.


Q: Can we test Resistance/Conductance of multiple blocks of cell once?
A: No, we can’t, because our way of measurement is not the old way of signal injection. Also, measurement of internal resistance or conductance is to help users fast detect the consistency of whole string and figure out the weak batteries with high resistance (or low conductance). Measurement of multiple cells at the same time will make it difficult to judge which cells are weak.


Q: Can I use the tester to measure Ni-cd and Lithium batteries?
A: Yes, besides standard battery types of 2V, 6V and 12V lead acid batteries, there is customized setting in the tester menu where users can add uncommon battery types including Ni-cd and Lithium batteries.


Q: How should I connect the alligator testing clamp or pin probe with battery?
A: To obtain best measurement accuracy and consistency, we will suggest always connect the clamps or pin probes with battery posts.
