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.

battery
The charging rate is current, which is in Amps. You need to divide the value by 10,000 to get the charging current in Amps. To get the charging power (in Watts) you multiply the current (in Amps) by the voltage, which is almost certainly going to always be 20V. In my case: (9566 / 10,000) * 20V = 19.1W.

Basics of battery charging circuit design
The charging current is reduced to more than 1% of the battery''s Ah rating. Lead-acid batteries can be kept on float indefinitely. In fact, keeping the battery on float will increase the battery''s useful life since it eliminates the possibility of self-discharge, draining the battery to unacceptably low levels and causing irreversible damage.
C Rate Calculator for Charge and Discharge Currents
2 · A 1C rate means that the charge or discharge current is equal to the battery''s capacity. For example, a 1C rate for a 20Ah battery would be 20A. How does the C rate affect battery life? Charging or discharging a battery at a high C rate can lead to increased heat generation and stress on the battery, potentially reducing its lifespan and ...
