Replacement Battery for Eaton UPS

The PowerWarehouse EBP-1803-PW is a sealed lead-acid battery built to replace the EBP-1803 module in Eaton Tripp Lite 9PX and SU series uninterruptible power supplies. It fits the 9PX5K, 9PX6K, 9PXEBM180RT and matching extended battery cabinets. Maintenance-free construction means no electrolyte checks are required.

Physical Limits of the Battery Module

The unit measures 18.5 x 8.25 x 4.5 inches and weighs 63 LB, so rack space and lifting capacity must be verified before purchase. It replaces OEM part 744-A1974 and supports cabinets rated for 180 and 360 volt strings. No other voltage or form factor is supported by this model.

Installation Notes and Common Issues

Installation is a straight swap: disconnect power, slide out the old pack, insert the new one and reconnect the same terminals. The heavy weight often requires two people or a lift. The most common problem is forgetting to torque the terminal bolts to the UPS manufacturer's specification, which can cause loose connections under load.

Questions about this item

Which compatible UPS model should I match this EBP-1803-PW battery to?

Match the battery to the exact Eaton or Tripp Lite model printed on your UPS — the list includes 9PX5K, 9PX6K, 9PXEBM180RT, SU5000RT and SU6000RT series units.

What runtime can I expect once the 63 LB EBP-1803-PW pack is installed in my 9PX5K UPS?

Runtime depends on the connected load; the 1803 pack restores the factory battery capacity so the UPS will deliver its original backup time at your current load level.

What connection interface does the EBP-1803-PW use and what does it limit?

The pack connects through the UPS proprietary DC battery bus; it is limited to the voltage and current ratings of the host 9PX or SU series chassis.
