Battery capacity is the amount of electrical energy a battery can deliver when fully charged. The capacity of a battery is determined by factors such as size, number of plates, the number of cells and the strength and volume of electrolyte. Common battery capacity ratings in use are: 1. Cold Cranking Amperes (CCA) 2. Reserve Capacity (RC) 3.
Reading battery specifications effectively is crucial for selecting the right battery for your needs. Key metrics include voltage rating, amp hours, cranking amps, and reserve capacity. Understanding these specifications ensures you choose a battery that meets your performance requirements while optimizing efficiency and longevity.
Although it is helpful to understand all of a battery's specifications, the most important are current and capacity. Current is the strength of the electricity discharged by a battery under use, and it is measured in amperes, commonly referred to as amps. However, the battery's rating is based on its capacity, which is measured in amp-hours (Ah).
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
