BATTERY CARE AND USE
STORAGE: If the unit is not in continued use, plug in the UPS every 4 to 6
months for 12 hours to recharge the battery. Warranty is void if the battery
discharges below the minimum battery cutoff point. To prevent such discharge,
DO NOT leave UPS ON for more than two days without plugging it in.
BATTERY LIFE & REPLACEMENT: Excessive battery use, storage at high
ambient temperatures, and lengthy periods in a discharged state greatly reduce
battery life. Your UPS maximizes battery life by limiting the depth of battery
discharge. You may replace the UPS battery yourself, but if you feel unqualified,
refer battery replacement to qualified personnel. Contact your local dealer or call
Liebert for a replacement battery.
WARNING: To replace batteries, turn OFF UPS and unplug it from utility supply.
CAUTION: Observe proper precautions. When replacing batteries, use the
same number and type of batteries. Proper battery disposal required. Refer to
local codes for disposal requirements. DO NOT OPEN OR MUTILATE
BATTERY. RELEASED ELECTROLYTE IS HARMFUL TO SKIN AND EYES
