LightAlarms 45139800 compatible UPS battery

This 12 V 12 Ah replacement cartridge is built for LightAlarms 45139800 UPS units. It supplies backup power to keep connected servers or network gear running during a mains outage. The pack weighs 10 kg and arrives factory fresh, ready for immediate deployment.

Simple drop-in installation with correct orientation

The cartridge slides into the UPS battery compartment and connects with the existing leads; no tools or firmware steps are required. Problems usually arise when the polarity is reversed or the terminals are not fully seated, which prevents the UPS from recognising the new battery.

Questions about this item

How can I confirm the 12 V 12 Ah battery is working after installation?

Measure the terminal voltage with a multimeter; a healthy unit reads near 12 V, and the UPS self-test should complete without a fault code.

What comes in the box and do I need any extra parts for the 45139800?

The package contains one 12 V 12 Ah battery cartridge weighing 10 kg; no additional cables or hardware are required for a direct swap.
