Introduction to Battery Ratings
Batteries are rated based on several factors, including their capacity, voltage, and discharge rate. These ratings are essential for determining the suitability of a battery for a particular device or application. The capacity of a battery, often measured in ampere-hours (Ah), indicates how much energy it can store. Voltage, on the other hand, refers to the electrical potential difference between the positive and negative terminals of the battery. The discharge rate, usually expressed as a C-rate, is a measure of how quickly the battery can supply its stored energy.
Understanding C-Rates
The C-rate is a critical parameter in battery specifications, representing the rate at which a battery is discharged relative to its maximum capacity. A C-rate of 1C means that the battery will supply its nominal capacity in one hour. For instance, a battery with a capacity of 2000mAh and a discharge rate of 1C will provide 2000mA of current for one hour. Higher C-rates indicate faster discharge rates; for example, a 2C discharge rate means the battery will supply twice its capacity in 30 minutes.
