Compatible UPS Battery Kit

This replacement kit fits the OneAC ONE300DA-SB uninterruptible power supply and contains two 12 V high-rate discharge SLA batteries. It restores backup power for connected servers and network equipment during mains failures. The kit arrives factory fresh with comprehensive installation instructions included.

Ready-to-Install Cartridge Design

Each battery is pre-wired into a cartridge that slides into the UPS chassis without soldering or custom cabling. The sealed lead-acid construction prevents leakage and allows mounting in any orientation required by the cabinet. High-rate discharge cells deliver the instantaneous current needed for graceful shutdown sequences.

Direct Replacement for Aged Cells

Swapping out depleted original batteries returns the UPS to its rated runtime without replacing the entire unit. The jump is worth it when self-tests report reduced capacity or when the last battery change exceeded the typical service interval. Buyers needing extended runtime beyond the standard cartridge should verify chassis space for larger packs.
