What this battery powers

The RefurbUPS PS-1290 is a 12 V 7 A sealed lead-acid cell built as a direct drop-in cartridge for compatible UPS units. It restores runtime to a single-battery backup system so the connected load stays powered during an outage. The kit includes one factory-fresh battery and printed replacement instructions.

Limits of the SLA chemistry

Sealed lead-acid cells deliver high surge current but have lower energy density than lithium alternatives and lose capacity if stored discharged. The 7 A rating defines the maximum continuous discharge the chemistry supports without voltage sag. Cycle life shortens at elevated temperatures, so the UPS enclosure must provide adequate ventilation.

When the swap makes sense

Replace the original cell when self-tests report reduced runtime or the UPS alarms indicate a weak battery. A fresh cartridge restores the original hold-up time for the same load without firmware changes. Do not use this single-pack kit for multi-battery UPS models that require matched pairs or higher voltage strings.
