+ | 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. | ||
