FAQ
Q: What is a Valve-Regulated Sealed Lead-Acid Battery (VRLA)?
A: A VRLA battery is a sealed lead-acid battery that utilizes internal oxygen recombination technology (oxygen recombines at the negative plate to form water) for maintenance-free operation. It is equipped with a safety valve to prevent excessive pressure buildup. There are two types: AGM (Absorbent Glass Mat) and Gel.
Q: How is a VRLA battery different from a conventional flooded lead-acid battery?
A: Sealed & Maintenance-Free: No water refilling is needed; the electrolyte is absorbed (AGM) or gelled (Gel).Oxygen Recombination: Minimizes gas emissions and allows horizontal installation (though upright is recommended).Safety Valve: Releases excess pressure to prevent swelling.
Q: Does a VRLA battery require an initial charge?
A: It comes pre-charged, but if stored for over 6 months, a supplementary charge is recommended before use (use constant voltage charging as per the manual).
Q: What is the correct charging voltage?
A:For 12V Batteries:Cycle Use: 14.4-14.8V (lower for Gel batteries).Float Charge: 13.6-13.8V (to maintain charge without overcharging).Always follow the manufacturer's specifications-excessive voltage can cause water loss or thermal runaway.
Q: How to determine if a battery is end-of-life?
A: Replace if:Capacity drops below 60% of the rated value.Voltage drops rapidly after a full charge (e.g., s12.0V for a 12V battery at rest).Internal resistance increases significantly (requires specialized equipment).
Q: How to store an unused VRLA battery?
A:Fully charge before storage.
