Lead purity in AGMs
Why the purity of the lead used by your manufacturer to create your AGM batteries matters. It also contains generally interesting info on AGMs including gassing rates and their impact on AGM servic...

Valve regulated Lead Acid (VRLA)
batteries are commonly further classified as:
Absorbed glass mat (AGM) battery
Gel battery ("gel cell")
An absorbed glass mat battery has the electrolyte absorbed in a fiber-glass mat separator. A gel cell has the electrolyte mixed with silica dust to form an immobilized gel.
While these batteries are often colloquially called sealed lead–acid batteries, they always include a safety pressure relief valve. As opposed to vented (also called flooded) batteries, a VRLA cannot spill its electrolyte if it is inverted. Because AGM VRLA batteries use much less electrolyte (battery acid) than traditional lead–acid batteries, they are sometimes called an "acid-starved" design.
