Whenever a Tripp-Lite UPS battery backup has a low battery, the "Overload/Check Battery" LED comes on, keeping the device from restarting. Even if you have fully charged the battery for it necessary four to six hours, a self-test reset has to be performed to make the "Overload/Check Battery" LED go off. If you are unsure when it comes to restarting your Tripp-Lite UPS when the battery becomes drained, do not worry. With the right instruction, you can restart it in less than a minute after the battery has been charged.
Step 1
Remove any of the electrical devices that you have currently plugged into the UPS. Manually power down each of the devices before disconnecting them from the battery backup.

Step 2
Turn the power on the UPS off by pushing the "On/Off" button until you hear a beeping sound, then unplug the battery backup from the AC outlet.
Step 3
See if your particular model has a circuit breaker "Button," or "Plunger," then press it inward. If the button is already pressed inward, or your model does not have this feature, continue onto the next step.
Step 4
Charge the battery for four to six hours by plugging the UPS into an AC outlet, while leaving the backup powered off. It may be a good idea to test the outlet first by connecting an electrical device, such as lamp, into its socket directly, to see if it is sending power to the UPS.
Step 5
Press the "On/Off" power button one again on the UPS to power up the device once again, then reconnect the equipment that you removed in the earlier step. Make sure that the UPS power rating is sufficient enough to power the devices you are connecting. All of the connected equipment should have its power restored by turning them on as well.
Step 6
Press the "On/Off" button for three seconds, or until you hear the second beeping sound. This initiates the self-test reset, which checks to see if the battery is capable of powering the connected equipment without AC current.
