Many times the battery is bad. But before you invest in a battery,test the battery. Volt meters are cheaper than batteries and everyone should have one, or a friend that does. It will show you if the battery is dead. And if it is you can test if the UPS is charging it or not at the battery terminals. This way you won't waste money on a battery for an ups with a bad circuit board.

I have a Tripp Lite G1010USB uninterruptible power supply that only powers the surge surge-suppressor outlets and not the battery-backup outlets. Unless the UPS is unplugged from the wall, and then i


You know they have a TWO YEAR Warranty ?

Sounds to me that it is faulty (one of the relays or switches is not providing 'through' power to the supposed 'backup' socket when the AC power is on.).

Have you followed the manual ?
available here http://www.tripplite.com/support/model/mid/G1010USB

Have you done a 'self test' ?
'To Run a Self-Test: With your UPS plugged in and turned on, press and hold the MUTE/TEST button for two seconds. Continue holding the button until the alarm beeps several times and the UPS performs a self-test. See "Results of a Self-Test" below.
Note: You can leave connected equipment on during a self-test.' see manual

If the LCD does not give you the answer then it is faulty. Seems like something went faulty on restarting your UPS in the morning.

Seems like plenty of help available from this companys' website.

Constant alarm but works fine otherwise


Jordan,

It probably burned up one of the capacitors on the board that signal the UPS to turn the alarm off. I've had this happen before and I unplugged everything, turned the UPS off, disconnected the batteries and then opened the UPS up to cut off the tiny, annoying, surprisingly loud speaker. I then put everything back together and that was the end of it :)

High frequency alarm sounds even when all components are unplugged from unit...even if I turn the unit off. The only way I can get it to stop is to unplug the unit.


You may have a problem with a Flat battery? Try taking the battery out and charging it, or swap it for a known good one, if this will not fix it, then you have a failure within the electronics, if this is so then it will need to be serviced by a professional.

Ups gave long continuous sound


Hi there,

A couple of things, first, are there any high-load devices plugged into the battery backup side of the unit? (Microwave, laser printer, and so on.) If so, there's your problem :). These devices cause a BIG load on your power system and need to be on the "surge protection only" side of the unit or plugged in to another surge suppressor.

If that isn't the case, it sounds like the UPS battery is bad. Here's something to try:

1. Shut the UPS off when this happens.
2. Take ALL load of of the "battery backup" plugs by unplugging them.
3. Start the UPS.
4. After the short self-test (the light blink and a few clicks are heard, in most cases), you should see a green light.
5. Plug in the loads that you unplugged from the battery backup side one at a time.
6. As you plug each one in, leave the ups turned on, but yank the power cord from the wall (unplug the ups from the wall while powered on and plugged in with a device drawing backup power from the unit)
7. Then, if the alarm goes off, you've confirmed that the battery can't take the load. So, it'll need to be replaced.

You can obtain ups batteries just about anywhere. (e.g www.planetbattery.com) All you need is the model number off of the battery and you can order a new cartridge. Make SURE the battery looks like and has the same voltage as the bad one to be sure your new one will function properly. Your manual should cover opening the battery door and replacing the battery.

Hello! I'm from Riyadh Saudi Arabia. I've left on my Tripp Lite UPS 1000 just last night. When I came in my office in the morning, my desktop computer including my computer server was OFF. I supprised that...


Unplug the computer. Then run the UPS self-test and the unit will display whether it finds an overload fault, whether the battery needs to be charged or replaced.
Here are the instructions (copied from the User Manual):
Turn UPS on: Press and hold the ON/OFF button for one second.

Run a Self-Test: Press and hold the MUTE/TEST button for two seconds (until alarm beeps several times).

The test will last 10 seconds. All LCD Display icons will be illuminated and the alarm will sound.

If the fault icon remains lit, the battery-supplied outlets are overloaded. Unplug powered devices until you remove the overload.

If the "Replace" icon remains lit and alarm continues to sound, the UPS batteries need to be recharged or replaced. Allow UPS to charge for 24 hours and repeat self-test.
