HI 800 SQ turn off after 2 - 3 mins. 3 LEDs flashing

This was originally posted on APC forums on 10/14/2011


Help repairing my HI - 800 SQ ups inverter ...

The inverter is charging the battery properly at 13.60 volts..
But when the line goes off it stays on for 2 - 3 minuits and turns off...

The FAULT LED, ON BATTERY and ON MAINS LEDs keps flashing...

Even when the inverter is on mains and I open the battery terminals the inverter does not show the fault..
Where as if the battery terminal is opened the FAULT led should flash and the inverter should beep...

I have attached the manual of the inverter below..

The serial number of the product is BB0950014478

The battery is just 1 year old...
I have another good APC Hi800SQ inverter.. When I connect that with this battery it runs well
SO there is not a battery problem..


I have charged the battery with an external charger and have tested the voltage.. It shows 13.92 volts.. I have tested the battery with a load too... Every thing is fine with the battery...




It is the inverter problem..
