Need good batteries. Then press and hold the power-on button until the magnetic relay is on.

If the device is over a few years old, then the batteries are probably dead. If so, they can be replaced. Below link shows some photos of the device once opened.

OK - I'll ask the simple question first, so don't think I'm being crappy...
When you hooked the wires back up to the batteries that were replaced, did you hook them back up as they originally were? (I ran into this problem myself earlier today. I put one of the batteries in upside down and didn't have them hooked up correctly.)
Red terminal on the front battery goes to the black terminal on the back battery, then the black terminal on the first battery goes to the circuit board. Red terminal on the back battery goes to the power supply.
Hope that helps. It sure is a pain the change these batteries out.

shut down the comp and the ups
unplug the cable from the comp and plug it in to the ups i/p
take the iec male to female cable that came with the ups and plug male into ups o/p and then female into your comp

turn on ups then turn on comp

thats it

hope this helps

thanks for using FixYa

check out this picture, it shows the 2 batteries wired up.

Notice that the batteries are flipped opposite of each other.
So from left to right its: bottom red, bottom black, top black, top red

Between the 2 batteries there is 1 red to black connection.
Then black to black-wire to circuit board
and red to red-wire to circuit board.

Check the manufacturer's web site for upgraded software on your UPS. This sounds more like a software problem.

Your batteries are weak...(causes
1:-not powering the UPS for a longtime
2:- long use(3 to 4 years) )...you will have to replace them
PLEASE RATE ME.................

look around the box and nottify the screw point open these screw and look for red and black cables that indicate the polarity of positive and negative, make sure the positive goes to it position as well as the negative on the new batteries.

that´s pretty strange and i would say that the batteries aren´t properly charged, try to let them charging over night without any load. good luck
