What is a Battery C rate?
The battery C Rate is the value at which a battery is charged and discharged. The battery's expansion here is the measurement of the battery's current. The general method of rating and labelling the capacity of a battery is at the 1C Rate. For example,
What is a C rating for a battery?
The general method of rating and labelling the capacity of a battery is at the 1C Rate. For example, A fully charged battery with a capacity of 120 amperes should deliver a current of 120 amperes per hour at a C rate of 1. If a 120 A battery discharges at a C rating of 0.5, it delivers 5A over two hours.
How do you calculate C rating of a battery?
The formula for calculating the C rating: I = Cr * Er, hence, [C-rate (C) = charge or discharge current in amperes (A) / rated capacity of the battery (Ah)] In which, Er = Rated energy (Ah); Cr = C Rate; I = Current of charge or discharge (Amps) To calculate the charge and discharge time, the formula is,
How do you know if a battery has a 1C rating?
Smaller batteries usually list a 1C rating, also called the one-hour rate. For example, if a battery is labeled 3000mAh at the one-hour rate, its 1C rating is 3000mAh. You can typically find this information on the battery label or data sheet. However, different battery chemistries use different C rates.
