It does not look good for this unit.
Time to upgrade, go bigger. Maybe this unit is too small for you system. Most likely a 1000VA will solve your problem.

Infinit loo between online and on battery?


With all 5 units behaving the same, I would expect that the power is still out of range. If the power is too high or too low (see manual for thresholds) the unit will stay on battery power to protect the attached equipment. If you have the software loaded, it will show you what the input AC voltage is at. Otherwise, it could be time for new batteries: http://batteryinternational.com/apc-smartups-1000-ups-battery-ups-batteries-f2.html

Keeps beeping every 2 seconds...


It sounds like its possible your battery is discharged or close to the end of its life, and needs to be replaced, but without better details its impossible to know the exact cause.

Sir after changing the battery ups worked well one day and the next day onwards when i pressed the switch red and amber lights blinking and the upc trips with beep sound .kindly give the solution


Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. There maybe one battery in a set of batteries that is faulty and causes the whole battery system to fail and indicate a battery fault.

These lower powered and cheaper KVA type UPS are switch over types, when the mains supply fail, the UPS switches over to the inverter in milli-seconds which then supplies mains power but the power waveform is a pseudo sine wave (ie not a true sinewave. A faulty inverter circuit won’t deliver power when the mains supply fails.

The true UPS types are usually the higher KVA units (over 1500 VA) that supplies uninterrupted mains power. The mains power is connected to a charger which charges the batteries and the inverter draws power from these batteries and converts it to true sine wave mains power therefore there is no switch over time lag from the mains to the battery.

APC 650 Pro not working properly.


My question is how long is the battery inside your UPS? 5years ? coz sometimes you cannot just base on the voltage you measure on the batteries. dont forget about the current that is being supplied by the batteries maybe the battery current is too weak to handle your load. but if you are really sure that your battery is good. try to check the inverter circuit of your UPS. or send it to UPS service center if you dont know how to check electronics component.
