    Firstly I would check the fuse on the plug, as this may be causing the error problems. There is no manual to be found for this unit, however it does include a 2year on site repair or replace warranty, if your unit is under two yeas old I would recommend using this service

SOURCE: Overload light in APC RS 800 UPS

it seems that the inverter circuit of your UPS is dying. the solution here is you have to open up the UPS and check the inverter circuit. to make easier, check the power mosfet if its leaking.

SOURCE: APC back-ups XS 800 battery backup : warning

Turn it off and unplug it from the wall.
Open it up and make sure that the red and black wires are connected.
If they are the battery needs to be replaced. They are only good for 2-3 years. If you are not comfortable with my instructions, call APC for free support. (800) 555-2725

Vote for this solution if it helps.

Mines, two or three years old and doing the exact same thing, you ever figure out what happen or how to fix it? I took the battery out and it reads 16 volts. I put a 2 amp load (fan) on it and it pulls fine, so I'm reluctant to buy a new battery pack for it now.

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.

27.5 volt charging voltage


No, that right. The batteries are wires in series so the voltage is 24v and they need a little high input than that to charge correctly.

"On Battery" Alarm Sounds when Power Available.


if this comes sometimes and goes, this means that the power to ups is sometimes deviating from the specific ups input range, hence the ups is rejecting it. mesure the input voltagesand frequency with a multimeter and check whether they match the specified ones in the ups manual. aslo with some ups there are switches that you use to set the input voltages or number of phases in the ups input. check the manual to see whetther your ups has such.

Charging apc 800va through home generators


The reason of this is the UPS cannot adopt on the frequency that is being generated by your home generator. you should use APC smart ups series coz smart-up series can work on a wider input frequency range.

Apc ups flashes red light to replace battery, but battery is new


i think by replacing the battery has not been the solution to the problem

u need to check the battery charging voltage when turned ON with main electricity, if no voltage present from charger, there is no question of battery getting charged and also once the battery is down with charge it may not re charge hence the indicator and alarm.
recomended to nearest service centre
