UPS backup problem

Hi Shrichandra,

Make sure that the battery you are using from the APC UPS is the correct one for the EnerG UPS, just because it fits doesn't make it the right one.

If you need UPS, Surge, or Power Related help contact Daniel with Power & Systems Innovations 800.260.2259 or go to our website: ** If this helped - click YES :) **

My APC ups doesn't power on

If your APC UPS is new but was stored unused for awhile, the battery may have discharged completely. You may find a comparatively less expensive and less time consuming solution is replacement.

Battery not connected properly. Check that the battery connector (rear panel) is fully engaged.
Press the on/test button once to power the UPS and the connected equipment.
Make sure UPS has nothing connected to it. Check the Fuses for the battery inside in the back of the UPS
Unplug UPS and batteries. Push the on button to clear the logic. It may or may not flash the LED's Once the fuses are checked, check the logic boards for any burn or discoloration.

My bajaj pulsar220F doesn't have enough pick up as before and its only been 6 mnths dat i purchased,Even i have done timely servicing

I'm assuming your talking about the batteries. You can purchase more batteries and put it in parallel to your existing batteries. it will give you longer run time.

The UPS only flashing the "bypass-led" and beep sound, but it doesn't put out any voltage to use.

You have a major fault. Try to reset the logic. UPS has to be off including the batteries. Call me at Gruber Power Services for free tech support. 800-658-5883 x256 ask for Eric

The UPS is either off, has a dead battery or is dead. Does the UPS power anything at the surge only outlets? If it doesn't, it's off or dead. Turn it on and check again.

The Omni 100 VS does not have a user-replaceable battery or other parts. If the battery or UPS is dead, replace it.

I hope this helps.

Why does the 4 outlets (surge only) of my cyberpower 685avr work while the 4 outlets with battery doesn't?

The battery only works when it isn't plugged into the wall. That's what a battery backup is for,so when the power goes out, the battery kicks in.
