Understanding Charge-Discharge Curves of Li-ion Cells
When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method. Hence, a CC-CV charger is highly recommended for Lithium-ion batteries. The CC-CV method starts with constant charging while the battery pack''s voltage rises.
Self-Discharge Current Measurement | Arbin Instruments
Battery Self-Discharge Current(SDC) is the small amount of electrical current that is lost naturally from a battery when it is not in use, due to internal chemical reactions within the battery. Measuring SDC accurately helps in understanding the health and efficiency of a battery, allowing manufacturers and users to predict battery life and performance more effectively.

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.
6 FAQs about [Battery discharge current in English]
What is a battery voltage & discharge current plot?
The plots show the voltage and discharge current for a battery with a response time of 30 s. Select to have the block determine the parameters in the settings based on the values specified for the parameters in the settings.
How long can a battery be discharged?
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
What is a typical discharge current for a NiMH battery?
For example, a typical discharge current for a 1.5-Ah NiMH battery is 20% of the rated capacity: (0.2 * 1.5 Ah / 1 h = 0.3 A). Internal resistance of the battery, in ohms. When a preset model is used, a generic value is loaded that corresponds to 1% of the nominal power (nominal voltage multiplied by the battery rated capacity).
What is a fully charged battery?
The fully charged voltage is not the no-load voltage. Nominal discharge current, in A, for which the discharge curve is measured. For example, a typical discharge current for a 1.5-Ah NiMH battery is 20% of the rated capacity: (0.2 * 1.5 Ah / 1 h = 0.3 A). Internal resistance of the battery, in ohms.
What happens if a battery is discharged after removing a load?
When removing the load after discharge, the voltage of a healthy battery gradually recovers and rises towards the nominal voltage. Differences in the affinity of metals in the electrodes produce this voltage potential even when the battery is empty. A parasitic load or high self-discharge prevents voltage recovery.
How do you write a discharge current?
The discharge current may alternatively be expressed as a multiple of the rated discharge current. For example, if the batt ery is specified at the 10 hour rate, I 10 = C/10 (Ah/h) and is the current which would discharge the battery in 10 hours. Then, if C = 40 Ah, I 10 = 40/10 = 4 A and a current of 10 A can be written as 2.5 I 10.
