What does VRLA, AGM, SLA and MF stand for?

“VRLA” stands for Valve Regulated Lead Acid, “AGM” stands for Absorbed Glass Mat, “SLA” stands for Sealed Lead Acid and “MF” stands for Maintenance-Free. All 4 of these terms basically refer to the same type of lead-acid battery. An example of this would be the pbq General Purpose series. These battery products are typically all black in color and designed for standby applications.
