Question about UPS Battery Backup Systems

2 Answers


I have a Leviton UPS with 6 outlets. Problem is I plug it up (with or without anything plugged in one of the 6 outlets) turn the toggle switch on. Then I get a normal green LED. Within 5 seconds the orange LED flashes about 4 times, then about 10 seconds later the unit trips off. I have checked internal fuses, checked the power cord with ohm meter for a short. Battery is fine, no sign of any thing on pc board getting hot. Anyone have any suggestions?

Hi,do I have to keep my ups plugged to a wall socke all the time?

the unit needs to be plugged in all the time. the unit is or should be fully automatic. higher priced units have a usb cord so you can check their status right on the computer, does your ups have a usb outlet? you might want to take it up to a computer store and buy a usb cable and then you can control your UPS with your computer. manually turning the UPS on and off shouldnt hurt anything.
good luck

When the power button is turned on my apc350 makes a high squeal sound, what is this? I have to have it turned on to use anything that is plugged into the battery backup outlets.

Double check the connections on the internal battery. If you have had the unit for a year or longer it may be telling you your back up battery isnt any good. I suggest replacing the battery, go here

I have an APC BE350U battery backup. When power is removed, all connected equipment stops and the unit beeps four times every 30 seconds. I have removed the battery from the case and checked the power...


The output on the battery should be around 14V, not 115V. If the unit is not holding the equipment powered when you remove the power, you need to get a replacement battery. The BE350 uses a 12v 3.5. Make sure to buy a high quality battery in order to get a good and reliable run time.

My ups battery brekar trips freqvently

UPS battery backups sometimes come with two ratings, one is continuous use, and the other is Peak use. In other words if you stay at the continuous load and it isn't in a hot area, or in a place where heat can build up (excessive heat lowers the UPS rating alot) you should be fine, but if you are over that rating and into the Peak rating for more than 10 seconds or so (varies) it will trip to protect itself. Or it could simply be a faulty breaker. Look at how much load you have
Just in case you dont already know, the way to tell how many amps any UPS can handle is to divide the va by the supply other words a 1200va UPS plugged into a 120v. outlet will handle 10 amps, but if you want a UPS that you are going to use at 10 amps you would want one that was rated for 1200va continuous, or better yet, go up to a 1500va and it will never let you down. Good luck.

Has started to beep whenever items plugged into

If it's more than 3 years old, you probably need new batteries.

If the beep started after plugging anything additional into the UPS, you may be in an overload state, and the beep is telling you that it's choosing to beep and not function as intended rather than smoking itself. Try unplugging a piece or two from it and see if the beep goes away. If not, probably just you're batteries giving out due to old age, they'll only give you 3-5 years.

APC ES-350 won't turn on; all I see is a blinking light.

Try looking for a small circuit breaker on the side that says "press to reset" - you could have tripped it accidentally when you unplugged the iPod.  Also, try pressing and holding the UPS power switch for 10-15 seconds.  That should force a power on as well.

Battery Backup/Surge Protector Question

Considering the low draw of power you intend for the UPS it will work well. I have two monitors on a strip plugged into UPS along with desktop, routers and modems, UPS handles all well, it's just shortens battery backup times. Have had to power down from outages several times without any probs.
