Battery is very easy to remove. Take it out and test it. If you dont have a meter to test it take it to an interstate battery store they will test it for you. They sell new ones should you need to purchace one.

Tripp lite keeps beeping after power on


Thank you for writing down what UPS it is and thanks for all the info you put on here. It help out a lot. If this is happing you might have a bad battery. Remember it only takes one bad one to fail. So if you can find the manual, note down how many times it beeps. In the back of the manual you will see, Troubleshooting Guide, there should be a section where you can decipher the beeps and it should tell you what alarm it is. Example 2 Beeps every 3 second intervals could indicate Low batteries, meaning your battery capacity is not at 100%. Need to replace the unit or the batteries. Again this an example. Also don't disconnect it unless you are ready to loose you power to whatever you are backing up. (Computers or printer, etc.) Not unless it doesn't matter what it's backing up.

How to stop beeping when on battery


Just depends if there is a display to enter into the menu and disable it. or by installing the software on to your laptop. But the software might be just for looking at metering such as voltages, currents, turning the UPS ON or OFF, etc. They usually allow you do disable the beep. But some don't allow you to do anything as to change settings. If you had a bigger ups with display, it will allow you. 3000va's and up, i believe.

Changing the battery

If your Tripp LIte Omni 1000 LCD display a fault icon and beeps after changing the battery, try the advice given by the buzzerman which worked perfect in this case:


1. Turn the UPS on. Press and hold the ON/OFF button for one second.

2. Run a Self-Test: Press and hold the MUTE/TEST button for two seconds (until beeps several times). The test will last 10 seconds. All LCD Display icons will be illuminated and the alarm will sound. At the end of this process the fault icon and the beeping turned off.

Tripp Lite SU2200 UPS has faults


For Tripplite UPS basically if the fault indicator is on you already have to check the power mosfets/IGBT on the circuit board. if you know the basic of UPS you dont need all those schematic diagram to check the thing. by the way, try to check your battery first if its still working. and if the battery is ok, go and check your inverter
