Emerson Channel Support.

NOTE
The internal battery pack is hot-swappable. However, caution should be exercised because during
this procedure the load is unprotected from disturbances and power outages. Do not replace the
battery while the UPS is operating in Battery Mode. This will result in a loss of output power and
will drop the connected load.

6.2 Battery Charging

The batteries are valve-regulated, nonspillable, lead acid and should be kept charged to attain their design
life. The Liebert GXT4 charges the batteries continuously when it is connected to the utility input power.
If the Liebert GXT4 will be stored for a long time, Emerson recommends connecting the UPS to input
power for at least 24 hours every four to six months to ensure full recharge of the batteries.
