Kit Contents

The RefurbUPS ONeAc ON400X-WL kit contains two sealed lead-acid batteries, each rated at 12 volts and 18 ampere-hours. The units are glued together as a single cartridge for straightforward installation. Manufacturer highlights confirm the batteries are factory fresh and built for high-rate discharge performance. Comprehensive replacement instructions are included in the package.

Ideal Use Cases

This kit suits administrators maintaining compatible OneAC UPS systems that require a 12V 18Ah battery pair. It is not for buyers who need a different voltage, capacity, or physical form factor for their specific UPS model. It is also not for users seeking lithium-ion chemistry or hot-swappable individual modules. Verify the exact cartridge dimensions and connector layout before ordering.

Critical Specification

The decisive specification is the 18 ampere-hour capacity at 12 volts per battery. This rating determines the available runtime and load support for the UPS. If the original equipment specifies a different ampere-hour value, the kit will not provide the correct backup duration. Match this capacity exactly to ensure proper system operation.
