AGM (Absorbed Glass Mat) VRLA (Valve Regulated Lead Acid) batteries are a type of sealed lead-acid batteries that are commonly used as a backup power source for critical applications, such as uninterruptible power supplies (UPS), telecommunications equipment, and solar panels.

AGM VRLA batteries are low-maintenance, as they don’t require periodic watering, and have a long service life compared to other types of batteries. They are also efficient in terms of their energy density and can provide high currents when needed. However, they are typically more expensive than flooded lead-acid batteries and have a lower tolerance for deep discharges. Overall, AGM VRLA batteries are a popular choice for applications that require a reliable and low-maintenance power source with good performance characteristics.
