Maintenance

9.0 M

AINTENANCE

The Liebert GXT2U requires very little maintenance. The batteries 

are valve-regulated, nonspillable, lead acid and should be kept 

charged to obtain their designed life. The UPS continuously charges 

the batteries when connected to the utility supply.
When storing the UPS for any length of time, it is recommended to 

plug the UPS in for at least 24 hours every four to six months to 

ensure full recharge of the batteries.
The Liebert GXT2U is designed to allow the user to safely replace the 

internal batteries. Read the safety cautions before proceeding. Contact 

your local dealer or Liebert representative to obtain the appropriate 

replacement battery kit part number and pricing.

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:

• Remove rings, watches, or other metal objects.
• Use a Phillips (crosshead) screwdriver with insulated grips.
• Do not lay tools or other metal objects on top of the batter-

ies.

• If the battery replacement ki

t is damaged in any way or 

shows signs of leakage, contact your local dealer or Liebert 

representative immediately. 

• Do not dispose of batteries 

in a fire. The batteries may 

explode.
