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.
A valve regulated lead acid (VRLA) battery is also known as sealed lead–acid (SLA) battery is a type of lead-acid battery. In this type of battery, the electrolyte that does not flood the battery but it’s rather absorbed in a plate separator or silicon is added to form a gel.
Valve Regulated Lead Acid (VRLA): VRLA battery systems capture and absorb the liquid electrolyte in glass mats placed between the lead battery plates. During charge and discharge reaction cycles the internal gases recombine which helps maintain desired levels of electrolyte and specific gravity.
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.
Valve Regulated Lead Acid (VRLA) batteries come in two main types: Absorbent Glass Mat (AGM) and Gel. Each type offers unique characteristics for various applications.
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.
