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.
