The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
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:
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.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
The tools needed to measure battery capacity accurately include a battery analyzer, multimeter, and load tester. To ensure accuracy in battery capacity measurement, understanding each tool's function is essential. Battery Analyzer: A battery analyzer tests the capacity of rechargeable batteries.
