What this battery is

The RefurbUPS CSB GP12180 is a 12V 18A sealed lead-acid replacement cartridge designed for compatible UPS units. It arrives as a single factory-fresh battery kit with installation instructions included.

Who this suits

It suits administrators who need a direct 12V 18A swap for a supported UPS and want a ready-to-install cartridge. Buyers whose UPS requires a different voltage, capacity or form factor should look elsewhere.

Capacity and headroom

The 18A rating delivers the specified runtime for supported UPS models under normal load. Runtime will decrease as the connected load approaches the UPS rated output, and the single-battery kit does not extend capacity beyond the original design.
