Battery Maintenance
•
On initial start-up it is recommended the batteries have a minimum of eight (8) hours of
charging to ensure proper operation.
•
During normal operation of the UPS, the charge level of the batteries will be maintained
automatically.
•
Under normal operating conditions, the supplied batteries are expected to last
approximately five (5) years, or 200 discharges, from date of receipt.
•
Refer to the purchase date you recorded in this manual if you suspect that the batteries
have been exhausted.
•
If the UPS is to remain in storage for an extended period of time, it is strongly
recommended that the UPS be powered up for a period of twenty-four (24) hours, every
three (3) months, to recharge the batteries and prevent premature failure.

Environmental Protection
The UPS incorporates sealed maintenance free lead-acid batteries or absorbent glass mat valve
regulated lead acid (AGM-VRLA) batteries. When replacing the batteries, the defective
batteries must be disposed of carefully to prevent any risk of environmental pollution by the
harmful products they contain (lead and acid). Please refer to local and regional environmental
codes when disposing of the batteries.
