Capacity refers to the total amount of electric charge a battery can store and deliver, typically measured in ampere-hours (Ah) or watt-hours (Wh). It indicates how much energy a battery can supply before it needs recharging and is one of the most fundamental metrics for evaluating battery performance.
Factors Affecting Battery Capacity:
Temperature: Low or high temps can reduce capacity
C-rate: High charge/discharge rates can lower usable capacity
Battery Aging: Capacity fades over time due to calendric and cyclic aging
Depth of Discharge (DoD): Frequent deep discharges can accelerate capacity loss
Manufacturing variation: Minor differences in production can affect initial capacity
