The fault started after the the surge board exploded but after the correction the ups start showing bat low,bypass light flashing,no output and shutdown
Test outlet power by switching the unit to manual bypass and breakers off.
If power is supplied OK and the filter board repaired OK then restart the unit starting with the breakers supply to unit,battery confirm the display is on and static bypass led also on then switch back the bypass knob to normal and press the on button to switch the unit to normal.
Give the batteries time to charge 12hours then you can test the unit on backup mode.

the battery is bad, you will need to replace the battery or the whole unit. you can find batteries on ebay. just source the model number. also depends on the size of the unit. you may need to just replace it...just a better value to do it that way.
good luck

Get an outlet tester. See http://www.acmehowto.com/howto/homemaintenance/electrical/outlettest.php
The tester will tell you what is wrong with the outlet.
SOURCE: After battery replacement, upon power
Try and push and hold the on button for about 3 sec. This will start a manual battery test. If only three of the five battery led illuminate allow the ups to recharge the batteries for 24 hours. Battery light flashing means internal battery source not available. Check battery connection, completely power down and reboot UPS
Testimonial: "Thanks, Battery source was not available - internal fuses were blown. Replaced fuses and unit is now functioning fine."
Pins 5 & 6 - Any-Mode Shutdown
1. Pin 6 of the 9-pin communication connector is used for "Any-Mode Shutdown"
of the UPS output. This control input may be used in special applications
to disable the UPS output power-both Inverter and Bypass.
2. The Options tab allows the behavior of the Any-Mode Shutdown feature to
be modified. When the program opens, or the REFRESH button is pressed,
the UPS setting is read by the configuration program and displayed.
Auto-Enable Output
Pin 6 Logic
If version 1.6 (or later) is used with an earlier Liebert GXT2U model (with an
earlier UPS firmware version), the Any-Mode Shutdown features cannot be
changed.
If the configuration program is used with an earlier UPS model (with an
earlier UPS firmware version) that does not support the modification of these
settings, the Options tab will display a reminder of the factory default
settings. These cannot be changed.
! WARNING
Note that when this option is selected and the UPS output is
disabled using Pin 6, the UPS output can turn on automatically
and without warning if the Pin 6 connection is changed.
! WARNING
DO NOT CHANGE THIS OPTION from the factory default
setting unless you are ready to install a normally-closed
connection between Pins 5 & 6. This connection must be
maintained to use the UPS or to use the configuration program
again, including the ability to change the UPS setting back to the
default setting using the configuration
