7.2 Battery replacement check

You can expect to receive 3 to 6 years of service life from the UPS's batteries when installed in a cool, dry location. Battery life is shortened when operated in an environment where the ambient temperature is normally above 30° C (86° F).

The UPS automatically performs a battery test upon start up and, if left operating, every 14 days thereafter. This test actually loads the battery for a brief time and will detect a weak battery before it is put into service during a power failure. If the battery is too weak to support the load during this test, the UPS will instantly return to on-line operation. The UPS will illuminate the Replace Battery indicator when it is detected that the batteries can no longer sustain sufficient charge. This means that the UPS would be unable to provide power for longer than half the normal interval (see section9.9) during an extended utility failure.

If the UPS illuminates the Replace Battery indicator, perform the following procedures to be sure that the batteries need replacing.

7.2.1Use the UPS's Line voltage bar graph to check that the utility voltage is within a normal range. The UPS will charge the batteries at a slower rate when operated from very low input voltages. Where low line voltages and frequent disturbances are common, set the UPS's Option switch 1 to the on ( I ) position - see section 5.0.

7.2.2Allow the UPS to charge the batteries for at least 8 hours following an extended utility failure.

7.2.3Recheck the UPS's batteries by conducting a battery test. Press the I/Test button to initiate the battery test.

7.2.4If the Replace Battery indicator does not illuminate following the battery test, the batteries do not require replacement. Extended storage without recharge, or successive power outages can cause false indications.

7.2.5If the Replace Battery is illuminated following the battery test, the batteries are worn and need to be replaced.

7.2.6Call the Customer Service phone number given on the cover of this manual to obtain information about battery replacement service or battery replacement kits.

Note: Please see the battery cautions at the beginning of this section.
