Charging the Valve Regulated Lead Acid (VRLA) 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.
What is a valve regulated rechargeable battery?
The Valve Regulated Lead Acid (VRLA) Battery is a type of rechargeable battery. They are also commonly known as sealed batteries or maintenance-free batteries. How are they made? To prevent the build up of the hydrogen gas (which may cause the battery to explode), a vent is used to relieve the pressure.
What type of battery is valve regulated?
lead–acid
Introduction. Valve-regulated lead–acid (VRLA) batteries with the capacity of about 1−6000 Ah have been widely used in uninterrupted power supplies (UPSs), light electric scooters, and other industry applications.
How do you maintain a valve regulated lead acid battery?
Professional Care Tips for VRLA Batteries
- Proper Charging.
- Use the Right Charger at All Times.
- Store the Battery in Good Conditions.
- Keep the Terminals Clean.
How do you charge a valve regulated 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.
Can you charge a lead-acid battery with a AGM charger?
In short, a regular flooded lead-acid battery charger can be used to charge AGM batteries, but the charging process requires monitoring and intervention on the part of the user.
Are AGM batteries valve regulated?
Both types are regulated by special one-way, pressure-relief valves and have significant advantages over flooded lead-acid products. The electrolyte in AGM batteries is completely absorbed in separators consisting of matted glass fibers.
Is AGM same as lead-acid?
The AGM battery and the standard lead acid battery are technically the same when it comes to their base chemistry. They both use lead plates and an electrolyte mix of sulfuric acid and water and have a chemical reaction that produces hydrogen and oxygen as a byproduct.
