What happens if a battery discharge current is 100 Ma?

With a higher discharge current, of 100 mA, the capacity falls to 1.15 Ah. By increasing the discharge current by 100, the overall capacity of the battery has fallen by nearly 66%. So if your device needs 35 mA to function and your cut-off voltage is 3 V, your maximum capacity will be 1.5 Ah and you will lose what is left of the battery’s capacity.

What is a battery discharge tester?

In each of these applications, the discharge tester is used to simulate a condition where the battery is required to give out its stored energy at a regulated rate until it’s discharged. This helps in verifying the battery’s state of health and its ability to perform when needed.

What happens if a battery is discharged constant power?

Keep the discharge power unchanged, because the voltage of the battery continues to drop during the discharge process, so the current in the constant power discharge continues to rise. Due to the constant power discharge, the time coordinate axis is easily converted into the energy (the product of power and time) coordinate axis.
