How do you know if a battery has a Max discharge current?

There is no generic answer to this. You read the battery datasheet. Either it will tell you the max discharge current, or it will tell you the capacity at a particular discharge rate, probably in the form C/20 where C means the capacity. You know the current you need : 4.61A.

How do you measure battery discharge power vs total energy?

Both discharge power and total energy can be displayed vs. time over the life of the battery. Figure 1. Using an analog multiplier to measure battery discharge power. In the example of Figure 1, using an AD534 multiplier, with impedance differential inputs, the total load on the battery is RL + RSENSE.

How to determine battery capacity for a low duty cycle?

1. The capacity of the battery for a low duty cycle of high current pulses will be according to the average discharge rate, rather than the high discharge rate. 2. If the pulse rate and duty cycle are not such that the battery can recover between pulses the battery life will be reduced compared with its average rate discharge curve.

What is constant current (CC) discharging?

1. Constant Current (CC) Discharging Constant Current (CC) discharging involves discharging the battery at a fixed current, regardless of the voltage drop as the battery discharges. How it works: During CC discharging, the battery’s current output remains constant. As the battery discharges, the voltage gradually decreases.

What are the charging and discharging methods of lithium batteries?

The most common charging method of lithium batteries In summary, the charging and discharging methods of lithium batteries are diverse, but in the final analysis, they are single-step or combined processes based on CC (constant current), CV (constant voltage), CP (constant power) or CR (constant resistance).

Can a battery be life tested with a prescribed load?

When a battery is life-tested with a prescribed load, its terminal voltage may be a poor indicator of how much of its energy has been discharged. Figure 1 is a circuit of a wattmeter that uses an analog multiplier to measure the actual power (volts × amperes) being delivered by the battery at a given instant.
