Free QuoteThe faster a battery can discharge, the higher its discharge rate. To calculate a battery's discharge rate, simply divide the battery's capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
The discharge rate provides you with the starting point for determining the capacity of a battery necessary to run various electrical devices. The product It is the charge Q, in coulombs, given off by the battery. Engineers typically prefer to use amp-hours to measure the discharge rate using time t in hours and current I in amps.
To calculate a c rate, divide the current of charge or discharge by the rated battery energy in amp hours. C-Rate is defined as the inverse of the time it takes, in hours, to charge or discharge a battery. For example, a battery that takes 2 hours to charge has a C Rate of 1/2 =.5. How to calculate the C Rate of a battery?
The charge and discharge current of the battery is measured in C-rate. The majority of portable batteries are with a rating of 1C. Which means that a 1000mAh battery provides 1000mA for just one hour if discharged at 1C rate. Exactly the same battery discharged at . 5C provides 500mA for 2 hrs.
For a more accurate estimation, you can assume 80% efficiency for NiCd and NiMh batteries and 90% efficiency for LiIon/LiPo batteries. Then, the formula becomes capacity / (efficiency * chargeRate) or, to use the same values from above (assuming lithium chemistry), 100Ah / (0.9 * 10A) = 11.11 hours Discharge rates are well enough covered here.
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.
