Comparator threshold setting of the BT3554-50

Home Service & Support FAQ Comparator threshold setting of the BT3554-50

QHow should I decide on the threshold values for the comparator of the BT3554-50? My target battery does not show the internal resistance in its specifications.

A

In general, the following is recommeded:

1) Measure the internal resistance of the fully charged new battery.
2) Set "x1.5" for WARNING and "x2.0" for FAIL
Then, set the rated voltage for the voltage threshold.

NOTE:
The internal resistancce value differs by the battery brand and model so be sure to different settings for each battery if you have several battery models to measure.
