The formula for determining the capacity of a lead-acid battery is: For example, if a lead-acid battery has a reserve capacity of 120 minutes, its capacity would be: It is important to note that the capacity of a lead-acid battery decreases as the temperature drops. At 32°F, the capacity is only about 60% of its rated capacity.
The first step in battery capacity measurement is choosing the right technique. As we’ve discussed earlier, there are several methods available, such as Coulomb counting, voltage-based methods, impedance-based methods, and hybrid methods.
The most reliable method for measuring the remaining capacity of a lead-acid battery is through a full charge and discharge cycle. This process involves charging the battery to its full capacity, and then discharging it completely while measuring the amount of energy it produces.
Accurate capacity measurements contribute to quality control, performance optimization, and efficient system planning, ensuring that we can continue to rely on battery-powered devices and systems for years to come. As a seasoned battery aficionado, I’ve learned a thing or two about measuring battery capacity.
1. Objective Methods other than capacity tests are increasingly used to assess the state of charge or capacity of stationary lead-acid batteries. Such methods are based on one of the following methods: impedance (AC resistance), admittance (AC conductance).
To calculate the capacity of a lithium battery, you need to know its voltage and amp-hour rating. The formula for determining the energy capacity of a lithium battery is: For example, if a lithium battery has a voltage of 11.1V and an amp-hour rating of 3,500mAh, its energy capacity would be:
