The S8BA-S480L is a replacement battery pack for the Omron S8BA series UPS units, specifically the S8BA-24D24D480SBF model. It delivers 25.2 V DC at 3.9 Ah capacity, using lithium iron phosphate (LiFePO4) chemistry — a chemistry choice that gives you a flatter discharge curve and better thermal stability than older lead-acid or lithium-ion packs. The terminal block connection means you land the wires directly, no proprietary connector to hunt down.
