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.
•
The typical recharge time to 90% from 0% charge level is 6-8 hours
•
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. 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.
