Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If the battery is discharged with a higher current, the real available capacity will be smaller (it may be much smaller). Discharging the battery with a lower current will extend the real available capacity a little bit.
CC-CV stands for Constant Current - Constant Voltage. It denotes a charging curve where the maximum allowed charging current is applied to the battery as long as the cell voltage is below its maximum value, for example, 4.2 Volts. Once the battery reaches that voltage level, the charge controller gradually decreases the current to hold the
Before starting to charge, first detect the battery voltage; if the battery voltage is lower than the threshold voltage (about 2.5V), then the battery is charged with a small current of C/10 to make the battery voltage rise slowly; when the battery voltage reaches the threshold voltage.

Charge Rate (C‐rate) is the rate of charge or discharge of a battery relative to its rated capacity. For example, a 1C rate will fully charge or discharge a battery in 1 hour. At a discharge rate of 0.5C, a battery will be fully discharged in 2 hours. IR drop – The drop in cell voltage due to the current flowing across the battery''s
For an identical current, a discharge time shorter than the charge time indicates low coulombic efficiency. At the end of the battery life, there is a decrease in battery charging and discharging times. The terminal voltage of a battery, as also the charge delivered, can vary appreciably with changes in the C-rate. Furthermore, the amount
