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.

tive immediately.
