1. Understanding Battery Capacity Battery capacity is quantified in ampere-hours (Ah) or milliampere-hours (mAh). It represents the total amount of charge a battery can store and deliver at a specific voltage. A higher capacity indicates a longer duration for which the battery can power devices before needing a recharge.
A multimeter can be used to measure the voltage of a battery, which can provide an estimate of its remaining capacity. However, this method is not as accurate as a full charge and discharge cycle. To use a multimeter, set it to measure DC voltage and connect the positive and negative leads to the corresponding terminals of the battery.
To calculate the capacity of a lead-acid battery, you need to know its reserve capacity (RC) and voltage. The reserve capacity is the number of minutes a fully charged battery can deliver a constant current of 25 amps at 80°F until its voltage drops below 10.5 volts. The formula for determining the capacity of a lead-acid battery is:
