Don`t charge the battery

Remove the battery, plug in the APC unit but do not turn it on. With a multimeter, place the leads on the proper connectors and turn on the meter and place it on the lowest DC setting to read DC voltage. The DC voltage should read 13.5 DC volts, which means the unit is capable of recharging the battery. If it reads low, for example, 6.44, then there's a problem. On the main board of the APC unit, it is more than likely a faulty capacitor.

Battery b/u squeals after unplugging everything

Hi Robert,The UPS will beep/squeal if the power isn't turned off to it before it is unplugged from the wall. But the other thing that may be causing the noise is a bad battery. Replacement battery price is $26.00.Reply or call if you need more help with this -- 407.380.9200

APC ES500 switches off and the red light blinks.

The battery for this unit is an APC# $^ (RBC46)
Also known as a UB-1280 (12 volts 8.0 AH- amp-hour)

Did you add a greater load ... like a small "heater"?
Remove most of the plugs for what is plugged into it and try again.

If you have a "printer" plugged into it, unplug it, from the "protected" side. It belongs on the "surge" side of the APC Battery backup.

Hope this helps!

I have APC be500 ups,

Going down the line. Does it have power? Do you use the powershoot program? Plug in the cable to the unit and what does current status say? if it says nothing, you probably dont have power or the unit is toast. If it says the line voltage is low or high, check it and if its really ok, there a number of parts that check the line and using another unit will probably tell which one. APC wont sell you parts or a schematic. So if you are not a excellant tech, send it in for about 40 bucks to get it refurbed or by a new one.

APC 500 beeps all the

It could be over loaded or too hot. Unplug everything and see if it keeps beeping. Or you can reset the logic. to do that turn off the UPS. Unplug from the wall. Disconnect the batteries. Push the on button. The LED's may flash. This is the logic reset. Put it back together and all should be good.

When i start my ups

Plug it in and turn on everything that you normally plug into it. If your UPS has good batteries it should stay online. How old is the UPS?

Backup power ends quickly even with new battery

What is the load on the unit? How old is it?

The symptom can occur if the load is too large. It will also happen when the unit reaches a certain age.

I've found that the low-end consumer UPS's should be replaced when the battery fails. The charging circuitry usually fails to charge the battery even with a new battery soon after the replacement.

The way I check if the battery or the UPS charging system has failed is with a voltmeter to give the current voltage and a variable DC power supply (whatever is appropriate for the battery) to attempt to charge the battery. I can watch the battery discharge with an oscilliscope if I want a full trace of the unit.) Charge the battery fully then watch the unit over time. If the battery itself is bad, you won't get the full charge or it will discharge as soon as it is removed from the power supply.

I hope this helps.

UPS swithed off as soon

The first thing to check is to make sure you plug you PC to the backed up outlet on your UPS.
As far as I remember only 3 out 6 outlets on that UPS are battery backed up. The other 3 are just surge protected.

It's printed on the UPS panel.

Hope this will help you
