Compatible UPS battery kit

This kit provides a direct replacement for Eaton Powerware UPS units that use the 153302033 cartridge. It contains one sealed lead-acid battery rated at 12 volts and 18 amp-hours. The package is designed for facility managers and IT staff who need to restore backup runtime without replacing the entire UPS chassis.

Sealed lead-acid thermal behaviour

The 12V 18Ah SLA cell operates without active cooling and generates minimal heat during normal float charging. Because the chemistry is valve-regulated, there is no electrolyte off-gassing under standard load, keeping acoustic output negligible. Power draw is limited to the UPS charger current, so the unit adds no measurable demand to the protected circuit.

Included installation instructions

The bundle ships with comprehensive replacement instructions that guide the user through safe cartridge removal and installation. Following the documented steps reduces the risk of short circuits and ensures the new battery is recognised by the UPS self-test routine. No additional software or firmware tools are supplied or required.

Questions about this item

How do I install the 153302033 battery kit in my UPS, and which step causes the most trouble?

Power down the UPS and disconnect it from mains. Open the battery compartment, remove the old cartridge, and insert the new 12V 18A SLA unit. The step people get wrong is reversing the red and black terminals — match the colours exactly to avoid a short.

What maintenance or replacement will the 153302033 kit need later?

The sealed lead-acid cell requires no watering or periodic servicing. Plan to replace the whole cartridge again in roughly three to five years, or sooner if the UPS reports a battery fault or runtime drops noticeably.

What limit appears first when the 153302033 battery runs under sustained load?

The 18 A high-rate discharge rating is the first ceiling you hit; drawing more current causes voltage sag and triggers the UPS overload protection. Heat buildup in the sealed case is the next limiting factor during long discharges.
