Explained: What Causes Battery Self-Discharge
Key Takeaways . Self-Discharge is Inevitable in All Batteries: Self-discharge is a natural phenomenon where batteries lose their charge over time even when not in use.This occurs due to internal chemical reactions within the battery, and the rate of self-discharge varies depending on the battery type and environmental conditions.
What is a safe max. discharge rate for a 12V lead acid battery?
Max Discharge Current (7 Min.) = 7.5 A; Max Short-Duration Discharge Current (10 Sec.) = 25.0 A; This means you should expect, at a discharge rate of 2.2 A, that the battery would have a nominal capacity (down to 9 V) between 1.13 Ah and 1.5 Ah, giving you between 15 minutes and 1 hour runtime.

What affects lithium battery discharge current
What does discharge current mean. The current flowing through the circuit in the discharge process is called the discharge current. For instance, the 1C rate means the entire battery will discharge within one hour, so if a battery has 100 Amp-hrs of capacity with 1C discharge rate, it will have 100 Amps discharge current.
Battery C Rating: Why it Matters for Lithium Batteries
Gather Information: Identify your battery''s capacity (in ampere-hours) and its maximum continuous discharge current (in amperes). Use the Formula: Calculate the Battery C Rating by dividing the maximum continuous discharge current by the battery capacity. For instance, if you have a 2Ah battery with a 10A discharge, the C Rating is 5C.
Li-ion battery maximum discharge current testing
Your charger can only discharge at a maximum of 1 Amp, which for a 3200mAh battery is 1A/3.2Ah = 0.3C.To discharge at 1C you need to draw 3.2A. Theoretically to get a 1C discharge you need a 3.2A constant current sink, but a resistor that draws ~3.2A on average is close enough.

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.
