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.
Discharge only occurs when there is a partial or complete outage in the utility network or during emergency conditions , , . The battery is recharged following the recovery of utility power. The battery is normally close to the fully charged state.
This guide to IEC/EN standards aims to increase the awareness, understanding and use of valve regulated lead-acid batteries for stationary applications and to provide the 'user' with guidance in the preparation of a Purchasing Specification.
Hence, the high regulation voltage, V ICC (1), is decreased to prevent the battery from overcharging when the temperature is high. Simultaneously, the duty cycle of the current pulse is regulated at its rated value (D ICC rated) to shorten the charging time and protect the battery from thermal runaway.
• Our VRLA batteries are protected against deep discharge because they are “acid-starved.” This means that the battery uses the power in the acid before it uses the power in the plates. Therefore, the plates are never subjected to destructive ultra-deep discharges. never runs out of water.
The process is the same for all types of lead-acid batteries: flooded, gel and AGM. The actions that take place during discharge are the reverse of those that occur during charge. The discharged material on both plates is lead sulfate (PbSO4). When a charging voltage is applied, charge flow occurs.
