7.2 Replacing the Battery
You can expect to receive 3 to 6 years of service life from the UPS's battery when installed
in a cool, dry location. If you suspect the battery is weak, allow the UPS to charge the
battery for at least 6 hours and perform the Test for proper operation described in section
3.7. If after repeating the test you find that the run time is still too short, follow the
procedures below to replace the battery.
Note:
Please read the cautions at the beginning of this section.
7.2.1 Turn off the UPS and unplug it from service. Lay the UPS on its left side and remove
the two battery door screws. Remove only the screws indicated on the battery door.
7.2.2 Gently pull out the battery by grasping the white tab.
7.2.3 Remove the two wires connecting the battery to the UPS. To loosen the wire
connectors, gently wiggle the connectors side-to-side while pulling straight back from the
mating battery connector.
7.2.4 Connect the battery wires to the new battery. The red wire is positive (+), the black
wire is negative (-).
7.2.5 Position the new battery as shown below and place it into the UPS. Arrange the wires
so that they will not interfere with the battery installation.
7.2.6 Close the battery door and fasten the two battery door screws.
7.2.7 Return the worn battery to the factory for recycling.
