Discharges MSXIV Cell Selection (Not Well-Controlled):
These files do not have well-controlled charge stages before the discharge stage was logged. Varying charge end currents as well as rest times between charge and discharge are possible. 4-terminal measurement for voltage was NOT used in these tests.
