Therefore, calculating the C rating is important for any battery user and can be used to derive output current, power and energy by: Cr = I/Er. Er = Rated energy stored in Ah. I = Charge/discharge current in A. Cr = C rate of the battery. t = Charge/discharge duration. Calculate charge and discharge time. t = Er / I
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery.
The charging/discharge rate may be specified directly by giving the current - for example, a battery may be charged/discharged at 10 A. However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery.
An equation is given for calculation of Charge/Discharge efficiency rate during charging mode which is: Eta= 1-exp (20,73* (SOC-1) / (I/I10)+0,55) Where I10 is the current at C10 I is the battery current
As the discharge rate ( Load) increases the battery capacity decereases. This is to say if you dischage in low current the battery will give you more capacity or longer discharge . For charging calculate the Ah discharged plus 20% of the Ah discharged if its a gel battery. The result is the total Ah you will feed in to fully recharge.
If the battery can only provide a maximum discharge current of about 50A, then the discharge rate of the battery is 50A/100Ah=0.5C. C-rate (C) = charge or discharge current in amperes (A) / rated capacity of the battery (Ah)
Capacity is calculated by multiplying the discharge current (in Amps) by the discharge time (in hours) and decreases with increasing C-rate.
Therefore, calculating the C rating is important for any battery user and can be used to derive output current, power and energy by: Cr = I/Er. Er = Rated energy stored in Ah.

For example, a battery with a maximum discharge current of 10 amps can provide twice as much power as a battery with a maximum discharge current of 5 amps. This number is important for two reasons. First, if you are using a device that requires more power than the battery can provide, then the battery will not be able to power the device and it will shut off.
