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 in Battery Mode. This will result in a loss of output power and will drop the connected load.

6.2Battery Charging

The batteries are valve-regulated, nonspillable, lead acid and should be kept charged to attain their design life. The Liebert GXT3 charges the batteries continuously when it is connected to the mains input power.

If the Liebert GXT3 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.
