Changing the batteries in your OPTI-UPS™ is a safe and easy procedure. Since the
battery is isolated from the AC input you may leave your UPS and computer or other
equipment on during the following procedure. Please note that if you choose to leave the
UPS on when the battery is removed, it will not be able to power your equipment if a
power failure occurs. Please read the cautions in section 6.1 before performing the
following steps.
1. Remove the two small screws from the bottom of the front panel.
2. Gently slide the front panel off.
3. Remove the battery retaining plate by loosening the six screws holding it in place.
4. Gently pull out the battery by the tape attached to it.
5. Disconnect the two wires connecting the battery to the UPS.
6. Connect the wires to the new battery, making sure that the red wire is connected to
the red battery terminal and the black wire is connected to the black battery terminal.
7. Push the new battery into place.
8. Reposition the battery retaining plate and tighten the six screws.
9. Slide the front panel back into place.
