Two 12 V 18 Ah batteries for OneAC UPS

This kit supplies two sealed lead-acid batteries rated at 12 volts and 18 amp-hours each. They are built as direct replacements for the OneAC ON1300A-SN cartridge. The units arrive factory fresh and include step-by-step installation instructions.

Check your UPS model and cartridge format

Verify that your UPS uses the ON1300A-SN cartridge before ordering. Confirm the existing battery pack contains two 12 V blocks wired in series. Ensure the physical dimensions of the replacement match the original housing so the door or tray closes correctly.

Drop-in cartridge restores runtime instantly

The glued pair fits into the UPS battery compartment without extra wiring or tools. Replacing the set restores the original backup time for connected servers or network gear. No firmware updates or configuration changes are required after installation.

Questions about this item

What is included in the ONeAc ON1300A-SN kit and what must be purchased separately?

The kit contains two glued 12V 18Ah high-rate discharge SLA batteries and comprehensive installation instructions. No additional parts are required for a standard UPS cartridge swap.

How do I choose between the listed versions or capacities for this replacement kit?

This specific kit is a fixed 2-pack of 12V 18Ah batteries designed for the ON1300A-SN model; there are no alternative capacities or versions to select for this part number.

What does the 1300 model number mean for runtime once the batteries are installed in my UPS?

The 1300 designation identifies the compatible UPS unit; actual runtime depends on the connected load and the UPS chassis efficiency, not on the battery model number alone.
