  • Weight3
  • Ready backup power for 300 VA UPS units

Product Identity

The RefurbUPS ULT33061 kit supplies a single 6 V 4.5 Ah sealed lead-acid battery designed to restore runtime to compatible 300 VA 150 W uninterruptible power supplies. It targets administrators and home-office users who need a direct, factory-fresh replacement for a depleted cartridge.

Installation Reality

The package includes comprehensive replacement instructions and the battery arrives factory-fresh, so installation typically involves opening the UPS battery door, disconnecting the old unit, and connecting the new one in its place. The main risk is reversing the polarity of the two terminals, which can damage the UPS electronics; careful attention to the marked leads prevents this error.

Capacity Limits

The 4.5 Ah cell supports the UPS rated output of 300 VA and 150 W, meaning runtime scales with the connected load and cannot exceed the unit's original design envelope. It does not increase the maximum wattage the UPS can deliver, nor does it add communication features or extended monitoring beyond what the host UPS already provides.
