How to charge a valve-regulated lead-acid battery?

For charging the valve-regulated lead-acid battery, a well-matched charger should be used because the capacity or life of the battery is influenced by ambient temperature, charge voltage and other parameters. Cycle use is to use the battery by repeated charging and discharging in turn.

How do you charge a lead acid battery?

The basic requirement to charge a lead acid battery is to have a DC current source of a voltage higher than the open circuit voltage of the battery to be charged. Figure 3 illustrates the basic concept of charging.

What are Valve-Regulated Lead-Acid Batteries?

Valve-Regulated Lead-Acid Batteries is a comprehensive reference source that provides essential insights into the science that underlies the development and operation of Valve-Regulated Lead-Acid Batteries. Copyright © 2004 Elsevier B.V.

What is the ideal charging voltage for a VRLA battery?

The ideal charging voltage for a VRLA battery is between 2.15 and 2.35 volts per cell. When charging a VRLA battery, it’s important to use a constant current charger. This type of charger will maintain a steady flow of current into the battery, which is necessary to achieve the proper charging voltage.

Does a VRLA battery need a constant current charge?

VRLA batteries require a constant current charge. This means that the voltage of the charger must remain steady throughout the entire charging process in order for the battery to reach its full capacity. Any fluctuation in voltage can damage the battery or cause it to not charge properly.

How do you charge a VRLA battery?

Naturally, the inrush current will be a function of the rectifier/charger constant voltage output and the battery depth of discharge. The modified constant voltage charger is essentially a regulated voltage power supply that is current limited. This is the most commonly recommended method of charging VRLA batteries.
