6.2 Charging Batteries
The batteries are LiFePO4 type Lithium-ion batteries. They should be kept charged to maintain their design life. The Vertiv™
Liebert® GXT5 Lithium-Ion charges the batteries continuously when it is connected to input power. If the UPS will be stored
for a long time, Vertiv recommends connecting the UPS to input power every 4 to 6 months for at least 3 hours to ensure
recharge of the batteries.
The Lithium-ion batteries used in the Liebert® GXT5 Lithium-Ion series, as well as all Vertiv Lithium-Ion UPSs, contain a
Battery Management System (BMS) that self-monitors the safety of the Lithium-ion batteries in real time. This is an agency
tested and certified requirement now eliminating the industry wide safety risk known with previous Lithium-ion batteries.
6.3 Checking UPS Operation
NOTE: Operation check procedures may interrupt output power supplied to the connected load.
We recommend checking the UPS operation once every 6 months. Ensure that output power loss to the connected load will
not cause data loss or other errors before conducting the check.
