BATTERY REPLACEMENT PROCEDURES
CAUTION – A battery can present a risk of electrical shock and high short
circuit current. The following precautions should be observed before replacing
the batteries:
- It is not necessary to turn off and disconnect the UPS from the utility power
prior to opening the battery replacement door; however, it is your option.
The UPStation GXT batteries can be replaced without turning off the UPS
or your connected equipment.
- Remove rings, watches, and other metal objects.
- Use a Phillips (cross head) screwdriver with insulated grips.
- Do not lay tools or other metal objects on top of the batteries.
- If the battery replacement kit is damaged in any way or shows signs of
leakage, contact your dealer immediately.
- Do not dispose of batteries in a fire, the batteries may explode.
- If you feel unqualified to replace the batteries, do not open the battery
door. Call Liebert Technical Support (LTS). World Wide Technical
Support numbers are located at the end of this section.
FOR 1800 TO 2700 VA RACK/TOWER MODELS:
CAUTION: The battery assembly is heavy (approximately 55 lbs (25 kg)). Take
proper precautions when lifting or moving it.
TOWER MODELS ONLY:
- Remove top cover by removing the two screws located on rear of top cover.
Push the top cover towards the back of UPS and lift off. Remove the two

lower, safer voltage.
3. Loosen the five screws of the large battery door. Remove the door by

wiring out and disconnect the battery connector.
5. Completely remove battery assembly from the UPS.
6. Unpack the new battery assembly taking care not to destroy the packing.
Compare new and old battery assemblies to make sure they are the same
quantity and voltage rating (see specifications). If so, proceed with the next
step; otherwise STOP and contact your dealer or LTS.
7. Slide the new battery assembly into the cavity, leaving 50mm (2 in).
