What is the Maximum Continuous Discharge rating of a lithium battery?

The maximum continuous discharge rating (often expressed in amperes, or A) indicates how much current a lithium battery can provide continuously without overheating or degrading its lifespan. This rating ensures that users can safely utilize the battery within its limits, which is essential for applications requiring sustained power output.

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.

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.

What happens if you discharge a battery in one hour?

Generally, for a given capacity you will have less energy if you discharge in one hour than if you discharge in 20 hours, reversely you will store less energy in a battery with a current charge of 100 A during 1 h than with a current charge of 10 A during 10 h. This phenomenon is significant for Lead batteries, much less for lithium batteries.

How long does a lead acid battery take to charge?

Last example, a lead acid battery with a C10 (or C/10) rated capacity of 3000 Ah should be charge or discharge in 10 hours with a current charge or discharge of 300 A. C-rate is an important data for a battery because for most of batteries the energy stored or available depends on the speed of the charge or discharge current.

What is a good battery capacity?

If it lists the capacity as 50Ah at C/20 (common for lead-acid), that's 2.5A so you might want a better battery. EDT as Andy says, if your device draws bursts of higher current, you also need to know the max (not continuous, maybe called peak) discharge current of your battery matches whatever your load needs.
