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.
To accurately measure the capacity of a car battery, it is important to follow the manufacturer’s instructions for conducting a capacity test. This typically involves charging the battery to its full capacity, and then discharging it completely while measuring the amount of energy it produces.
Capacity test is the only way to get an accurate value on the actual capacity of the battery. While used regularly it can be used for tracking the battery’s health and actual capacity and estimating remaining life of the battery. When the battery is new its capacity might be slightly lower than specified. This is normal.
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).
Start discharging the battery while recording the time taken until the voltage drops to a specified cutoff voltage (typically around 10.5V for lead-acid batteries or 3.0V per cell for lithium-ion batteries). Note the total time and average current during the discharge. Capacity (Ah) = 2A × 5h = 10Ah. B. Using a Battery Analyzer
