So, what is C-Rating?
When describing the battery, the discharge current is usually expressed as c-rate to normalize the battery capacity, which usually varies greatly between the battery brand and size.
C-rate is a measure of the discharge rate of the battery relative to its maximum capacity. If you simply regard the letter "C" in these expressions as the value of the ampere-hour class, it is easier to understand.
You can use the capacity of the battery and the c rating of the battery to calculate the number of amperes that it can continue to discharge until it runs out of power.
For example, if you divide a 100Ah battery by its c-level C10, you will get 10A or 10amps. So this battery can be discharged for 9 hours at 10A until it is dead without overheating.
Different C-level
For the same battery, the battery capacity varies with the c-rate. The faster the battery discharges, the smaller the capacity. This will vary depending on the battery type and chemical composition.
Two batteries with different capacities and different c ratings can have the same discharge capacity.
For example:
12V180Ah battery C10=15.8A
12V90Ah battery C5=15.8A
However, they will not last the same time!
12V180Ah battery C10=6 minutes
12V90Ah battery at C5=12 minutes
