6 FAQs about [Lead-acid battery safety valve production]
What happens when a lead acid battery is discharged?
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.
Why are VRLA batteries acid-starved?
Our VRLA batteries are designed to be “acid-starved.” This means that the power (sulfate) in the acid is used before the power in the plates. This design protects the plates from ultra-deep discharges. Ultra-deep discharging is what causes life-shortening plate shedding and accelerated positive grid corrosion which can destroy a battery.
Can you put a lead-acid battery in a sealed container?
Do not install any lead-acid battery in a sealed container or enclo-sure. Hydrogen gas from overcharging must be allowed to escape. Always use a reliable, temperature-sensing, voltage-regulated, automatic charger. Because SVR batteries have immobilized electrolyte, they cannot spill or leak, even if punctured.
What is valve-regulated lead-acid (VRLA) technology?
Valve-regulated lead-acid (VRLA) technology encompasses both gelled electrolyte and absorbed glass mat (AGM) batteries. Both types are valve-regulated and have significant advantages over flooded lead-acid products.
Why are VRLA batteries protected against deep discharge?
• 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.
Can a VRLA battery be used in a flooded battery?
VRLA batteries can be substituted in virtually any flooded lead-acid battery application (in conjunction with well-regulated charging), as well as applications where traditional flooded batteries cannot be used. Because of their unique features and benefits, VRLA batteries are particularly well suited for: What is a gel battery?
