Understanding how to accurately gauge capacity enables users to make informed decisions regarding maintenance, usage, and replacement. This guide delves into detailed methodologies for measuring the capacity of common battery types, particularly focusing on lead-acid and lithium-ion batteries.
Here, we describe the application of Incremental Capacity Analysis and Differential Voltage techniques, which are used frequently in the field of lithium-ion batteries, to lead-acid battery chemistries for the first time.
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.
Two major standardized testing procedures for battery capacity are the International Electrotechnical Commission (IEC) 61960 and the Institute of Electrical and Electronics Engineers (IEEE) 1725 standards.
Estimate the remaining capacity: Multiply the SOC by the battery’s rated capacity to estimate the remaining capacity. Let’s assume we have a 12 V, 100 Ah lithium-ion battery, and we want to estimate its remaining capacity using a hybrid method that combines coulomb counting and voltage-based methods.
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.
B) Health check capacities are measured every 50 cycles and charted. Fig. 5 A shows the C 10 capacity of 12 V/220 Ah battery at the beginning (0), middle (100), and end (1700) of cycling. In the literature this plot is used for measuring capacity of the battery, i.e., State of Health (SOH), at various cycles.

To specify the goal; a reliable method to estimate a battery''s State of Health would be to, from measurements of the battery and knowledge of its specification, obtain an algorithm that returns the capacity and State of Charge from the battery.
For example, in a system, the components are 5kW and the voltage of the battery pack is 48V, then the maximum charging current of the battery is about 100A. If it is an ordinary lead-acid battery with a maximum current of 0.1C, the battery capacity should be at least 1000Ah; If it is a lead-carbon battery with a maximum current of 0.25C,the ...

When we talk about lead-acid batteries, "battery acid" refers to the electrolyte solution used in the battery. In lead-acid batteries, this is a mixture of distilled water (pure H₂O) and sulfuric acid (H₂SO₄). Sulfuric acid can be dangerous because it is odorless, colorless and strongly acidic so take precautions when working around batteries, especially if the electrolyte …
This is of interest when capacity tests are restricted to determine the aging. For lead-acid batteries, for example, this is the case in applications like micro-hybrid vehicles or uninterruptible power supply systems. However, the interpretation of impedance spectra of lead-acid batteries necessitates proper measurements, elaborated verification of measurement …
