What is standard discharge current?
Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If battery is discharged with higher current – real available capacity will be smaller (it may be much smaller). Discharging battery with lower current will extend real available capacity a little bit.
What is charge current and discharge current?
The charging rate, in Amps, is given in the amount of charge added the battery per unit time (i.e., Coulombs/sec, which is the unit of Amps). For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A.
What is a 1C discharge rate?
A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps.
How is the discharge current related to capacity?
Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If battery is discharged with higher current – real available capacity will be smaller (it may be much smaller). Discharging battery with lower current will extend real available capacity a little bit.
What should the discharge current be on a battery?
In general you might expect this number to be something like 1/5 or 1/10 of the C rate, meaning a 5 hour or 10 hour time to fully discharge. Maximum continuous discharge current sounds like what is the maximum drain current that will remain safe on the battery without “abusing” it and thereby shortening battery life.
What should the standard current be on a battery?
Continuous standard current sounds like “nominal” drain current, what current does the manufacturer expect to be a typical load under ordinary usage, probably much less than the maximum. In general you might expect this number to be something like 1/5 or 1/10 of the C rate, meaning a 5 hour or 10 hour time to fully discharge.
How long does it take a battery to discharge at 3C?
For example, at a current of 3C, this stage is reached in just over 6 min or 0.1 hour and the extractable capacity is only [3C (A) x 0.1 (h)], i.e. 0.3 C or 30% of the nominal capacity. Note that the average voltage at a discharge current of 3C has fallen to approximately 80% of the voltage obtained at much lower currents.
