| Historical note: the original use for AGM was for long-term stationary floating on shore power for backup/UPS purposes, as one finds in industrial backups or in the bases of cell towers. In long-term stationary use the liquid electrolyte in flooded batteries can stratify, causing degradation. The electrolyte in AGM(((and gel)) types cannot move freely and so will not stratify. Telcos and other industries typically replace the batteries after X years on float duty and sell them on the surplus market. They are not made for frequent cycling but still may represent a good value. | Historical note: the original use for AGM was for long-term stationary floating on shore power for backup/UPS purposes, as one finds in industrial backups or in the bases of cell towers.

| Having said that, if one is aware of the limitations of the battery it can play a role in the campervan, particularly as a "learner battery" that the [[electrical:batterycide|beginner often murders]]. Lifespan on these batteries can be maximized by cycling lightly, perhaps 20% [[electrical:depth_of_discharge|depth of discharge]]. They can also be used for people who are not away from shore power very long: | Having said that, if one is aware of the limitations of the battery it can play a role in the campervan, particularly as a "learner battery" that the [[electrical:batterycide|beginner often murders]].
