Frequently asked questions
How do I measure a battery's capacity with it?
Fully charge the cell first, since capacity readings depend on its state of charge. Connect the cell as the module's labelling indicates and read the mAh and mWh values on the display, following the module's instructions.
Are the readings laboratory-accurate?
Results depend on the load, the cell's condition and the test conditions. Treat them as an estimate for comparing cells rather than a lab-grade measurement.
