AINTENANCE
The Liebert GXT2-10000RT208 requires very little maintenance. The batteries are valve-regulated,
non-spillable, flame retardant, lead acid and should be kept charged to obtain their design life. The
UPS continuously charges the batteries when connected to the utility supply.
When storing the UPS for any length of time, it is essential to plug the UPS in for at least 24 hours
every four to six months to ensure full recharge of the batteries. Failure to recharge the batteries peri-
odically will permanently degrade battery capacity.
The Liebert GXT2-10000RT208 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.

Both battery packs should be replaced at the same time.

cover grille. Lay the battery cover grille aside for
reassembly.

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 and other metal objects.
• Use a Phillips (crosshead) 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 local dealer or Liebert representative immediately.
• Do not dispose of batteries in a fire. The batteries may explode.
NOTE
These are hot-swappable replacement batteries. However, caution should be exercised because
during this procedure the load is unprotected from disturbances and power outages.
