So you had the system is storage? If that is the case then it is probably time to change the battery. Storing batteries when they aren't fully charged, or in extreme temperatures can damage the battery. You can check out http://www.batteryinternational.com/ups-batteries.html for a replacement .

APC Back-UPS ES500. Battery is new replacement UB1280, and battery has charge and runs fine if unit not plugged in. However, if unit is plugged in to power back-up side outlets in unit don't work.


there are 2 parts of a UPS .
the charge side
and (battery is obvious)
the inverter side.
if the charger fails, all is lost. (are the batteries in backwards?)
if the charger works (volt meter tells you that)
then the inverter is bad. (this unit is not full time UPS , but part time, this means it switches over to inverter at power fail.
(on full time sys. inverter runs full time, like the name states)
the unit, you mean the load right.?
the UPS side plugged into a load. and the load is now dead.

the Backup plugs should work if the mains are hot.
if you kill mains, the inverter will fire off, (hear the squeal?)
and give you 500 watts for some minutes, sucking the batteries dry. (see load run time curves)
I used to do service on HUGE UPS systems, some with 100s of batteries. 3 to 5kw too.
on ours there is a port on the rear , we connect and can
check everything "BEST brand" even charge voltage.
did you look on APC site for special software and connections?

the manual does cover trouble shooting, ever read that?
RTM? start there, its online, for sure.

APC BACK-UPS ES 500VA fails to provide back up during power failure


Get APC Powerchute Personal Edition for free and run it. If it says your battery isnt charged, check its voltage disconnected. Charge it with a car battery charger and see if its still a good battery. If not , replace it. If the battery is good, then check the charging voltage. Should be about 14 volts. if not, check the small transformer on the main board. Should be 120 in and 17 to 18 out. 4 diodes in a bridge for charge. The input to the transf has small fuse into it alone.

Hello sir, I don't actually know how to charge my apc cs 650... and And when the power is out, so does my computer.. low battery.. I just need a simple answer about this.. is it not charging? or do i need...


If you connect the control cable to a PC and install the PowerChute Personal Edition V3.0.2 f software you should be able to see if it is charging and what the percentage of charge held in the battery is.

On the CS 650 the lowest power connection is the surge only powerpoint.

To give the battery a full charge or to test it you can connect it to a car battery trickle charger, as it is a 12 volt battery, rthis will at least mean you can check that it holds a charge in the first place.

My UPS has continuous sound. I bought it before 2 years. What could be its problem?


Hello; It has to be the problem with the battery. May be the battery in UPS must be in a out of complete charge and wont get charge as its loosing its life. Normally UPS should be switched on only when the system is used and has to be switched off when not in use. This may extend the life of the battery. And most of the UPS battery comes around 1 yr or 1 1/2 yr. So try checking your battery status.

APC Backup UPS Model # BK200C salvageable?


Yes, but the battery may not be any good, though, and trying to charge it may damage the charger. A new battery is about $20. The surge suppressor will still work without the battery as long as it is connected to a properly grounded 3-wire circuit. If you decide to take a chance and charge the old battery, take precautions like keeping a watch on it should it explode or catch fire. Not trying to scare you, just looking at worst case scenario.

APC ES350 strange noise


My solution was to unplug everything, hit the reset button, and then power the unit back up. The problem I found to be that I had my laser printer connected to the "surge + battery" side, and for some reason no laser printer can be connected to it.

1) Switch Off the UPS and unplug all Loads (like System, Monitor etc.) from UPS.
2) Switch Off the AC Power (Input Power to UPS).
3) Press the UPS Power Switch constantly unless you hear 2nd BEEP Tone. As soon as you are hearing 2nd BEEP Tone, Release the Power Switch.
4) This is COLD START of all APC UPS that will reset any internal problem.
5) If, however, the problem persists, contact APC.
