Compatible Replacement Battery Kit

The RefurbUPS ONBP-405 kit provides four 12V5A sealed lead-acid batteries designed as direct replacements for compatible UPS units. It targets administrators who need factory-fresh cells to restore runtime on existing power-protection hardware.

Build Quality and Connectors

Each cartridge uses high-rate discharge SLA chemistry and arrives ready for immediate installation. The package includes comprehensive replacement instructions so technicians can swap cells without specialised tools or extended downtime.

Practical Limits of SLA Chemistry

Sealed lead-acid cells deliver reliable backup but degrade with age and temperature, so runtime will gradually decrease over the service life. The kit does not add capacity beyond the original specification, so loads exceeding the UPS rating remain unsupported.

Questions about this item

Does the ONBP-405 kit use a standard 12 V SLA interface for UPS cartridges?

Yes, it contains four 12V5A sealed lead-acid batteries that match the voltage and terminal layout expected by compatible UPS battery compartments.

What physical space and weight should I allow for the four batteries in the ONBP-405 kit?

The complete kit weighs 20 and comprises four square 12V5A blocks; allow enough rack or cabinet depth for four side-by-side units plus cable clearance.

How do I install the ONBP-405 batteries and what step is most often missed?

Power down the UPS, open the battery door, disconnect the old pack, connect the new batteries in the same series order, then torque the terminal bolts to the UPS maker's spec — the step most skipped is re-torquing after the first charge cycle.
