The observed probe
Voltage / VThe model uses this electrical trace plus temperature averaged over the longer recording. The heavier-load response stays hidden.
Response to a heavier load
How does voltage recover after the load ends?
Njal estimateBench measurement
Pulse resistance
— mΩ
How strongly the cell resists current under load.
Capacity
— % nominal
Charge-storage capacity relative to the rated capacity.
