|description===Production process==

*Before the cells leave the factory, they are tested in an EOL test rig.
*The cells are removed from the good carriers in the aging racks and fed to the testing station.
*Here they are discharged to the shipping state of charge (capacity measurement).
*Depending on the manufacturer, pulse tests, internal resistance measurements (DC), optical inspections, OCV tests and leakage tests are carried out.
*After testing, many cell manufacturers sort the cells according to their performance data (grading).
*Once the tests have been completed passed successfully, the cells can be packed and shipped.
*For transport, the cells are usually provided with a plastic cover and stacked in a cardboard box.

==Process parameters & requirements==

*State of charge of the cell for shipping: 5 % - 20 % SOC
*Permissible loss rate: < 5 mV per week
*Increased loss rate: > 5mV per week may indicate e.g. cell-internal short circuits

==Technology alternatives==

*Different test sequences and durations exist depending on the cell manufacturer.

==Quality influences==

*Cell handling

==Quality characteristics==

*Low self-discharge
*Low internal resistance
*Constant capacity
