Key Concepts

Battery Capacity

Battery capacity is a measure of the total amount of charge a battery can store, typically expressed in ampere-hours (Ah). It represents how much current the battery can deliver over a specific period and is fundamental for estimating how long a battery will operate under a given load.

Current

Current is the rate at which electric charge flows, measured in amperes (A). In the context of battery discharge, it denotes how quickly the stored charge is being drawn from the battery by a connected load.

Battery Discharge Equation

The battery discharge equation relates the battery’s capacity to the current draw and the time until the battery is empty. The fundamental formula is Q = I × t, where Q is the battery’s capacity, I is the current, and t is the time. Rearranging this equation gives t = Q/I, which determines the time required to discharge the battery completely.
