SOURCE: 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

Your UPS is having an internal problem, it should be an inverter problem. if you know how to troubleshoot up to component level try to open the UPS and check the power mosfets. if not bring your UPS to the service center.

SOURCE: I bought replacement batteries for APC XS900

Measure the voltages of the replacement batteries with a Voltmeter - are they lower than its' full charge? Allow them to charge before you connect any load to the UPS. It might take several hours before they fully charge. Occasionally measure the batteries in circuit to see if they are charging - you will need a Voltmeter again.

APC SURT3000XL UPS


The fault indicator means that there is a fault in the circuitry of the UPS. It could be the control board or another part of the system. (If the batteries were bad, you would see the Replace Battery light illuminate.) If the SURT3000XL is under warranty, contact APC. The standard warranty period is 2 years for repair/replacement. Note: you'll probably have to pay for the shipping of the unit. If the unit is out of warranty, replace it with a new UPS.

I hope this helps.

This alarm indicates that the Battery PowerSupplied outlets are now supplying battery power as opposed to power from theutility. If the UPS determines that the input utility power is unsafe for yourcomputer equipment, the UPS will switch to battery power.

Once the UPStransfers to On Battery operation, it can only stay on battery for a limitedamount of time. The UPS will sound this alarm about two minutes before thebatteries are totally exhausted. Once exhausted, the UPS will shutdown and turnoff its output power to your equipment. If you hear this tone you shouldimmediately shutdown your computer to prevent data loss or corruption.

I connected 8, 100Ah battery with APC 2.2KVA inverter, now it doesnt give correct battery indication and keep producing beeping noise, whats the problem?


Continuous Beeping (theamber On Battery LED will be illuminated)
This alarm indicates that the UPS has reached aLow Battery condition and will soon shutdown. The UPS can only operate onbattery for a limited amount of time. In order to protect the unit's batteriesfrom discharging too much, the UPS will shutdown and turn off its output. Towarn you that the unit will soon shutdown, the UPS will sound this alarm 2minutes before actual shutdown. With optional Powerchute Plus software, 2minutes can be changed to 5, 7, or 10 minutes to give you more of a warning ofimpending shutdown. If you hear this tone, you should immediately gracefullyshutdown your operating system to prevent data loss or corruption.
Note:This graceful shutdown will occur automatically if Powerchute PLUS software isbeing used.

Constant, Solid Tone (the red Overload LEDwill be illuminated)
This alarm indicates that the UPS has detectedan Overload condition. If this alarm is sounded, try removing non-essentialequipment. The alarm will remain until the load is reduced. To determine ifyour UPS is capable of handling the equipment you want to protect, visit APC'sSizing Guide at www.apcc.com/sizing.

Continuous Beeps for One Minute; RepeatedEvery 5 Hours (Replace Battery LED will be illuminated)
This alarm indicates that the UPS has failed itsSelf-Test of the battery. The unit will continue to sound this alarm until theunit passes the test. Try to let the unit charge for a few hours and thenperform another Self-Test (Press and hold the on/off button until the second'chirp', then release). If it fails and the unit is still in-warranty (twoyears from date of purchase), then contact APC. If the unit fails and its outof warranty, then order a replacement battey cartridge through your reseller,distributor, or from APC's web site.

If the device was still under warranty, you should call APC support and ask to send it in for repairs or replacement. Just keep politely asking, and ask to talk to their superior whenever they say it isn't possible and eventually you will get an RMA ticket/number.
If the device is not under warranty, you might be able to convince APC to service the device for a fee.

Unit plugged in but nothing hooked to it overload light and alarm comes on


I am confused, you say something is plugged in BUT nothing "hooked" to it, what do you mean???

Possibly the capacity of the UPS is too small for your PC / monitor etc.

My suggestion would be to replace the battery to make sure the battery is not shorting out the UPS. If you can't do that, take out the battery and then replug the UPS back in.

If you still get the same results then that means the main board inside of the ups system is bad and you would need to get a new UPS system.

APC back-ups es500 alarm continuously sounds why we power it off and alarm stops everything works fine then we power it back on and alarms sounds again


It means it has an internal fault. if still under warranty period, just call APC and ask for replacement. if it out of warranty bring it to service center or better if you have to buy a new one because as far as i am concerned repair cost of this unit is much expensive than a new unit
