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.

7.2.1Turn 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.

7.2.2Gently pull out the battery by grasping the white tab.

7.2.3Remove 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.

7.2.4Connect the battery wires to the new battery. The red wire is positive (+), the black wire is negative (-).

7.2.5Position 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.

7.2.6Close the battery door and fasten the two battery door screws.

7.2.7Return the worn battery to the factory for recycling.
