So something happened to this apc and the first thing is to replace batteries...
I'm going to guess major circuit board failure.
go to apc site, download Power Chute software and pray there are useful diagnostics.

follow this steps and fix it. God bless you
Plug the battery backup into a working electrical outlet. If the battery backup turns on when the power button is pressed, then the problem may be that the previous electrical outlet is faulty. Proceed to step three. If the battery backup doesn't turn on, proceed to step two.

2 Reset the circuit breaker on the battery backup. APC battery backups have a labeled circuit breaker button located on the unit near the phone line, fax line, USB, network and coaxial cable inputs. Press the button to reset the circuit breaker. Power on the battery backup by pressing the power button. If the battery backup powers on, proceed to step three. If the battery backup doesn't turn on, proceed to step six.

3 Determine if the battery backup is charged and providing battery power. With the battery backup on and plugged into a working electrical outlet, plug a computer monitor into one of the battery backup outlets labeled "battery backup plus surge protection" on the battery backup. (APC power supplies have some outlets that provide only surge protection while the other outlets provide surge protection plus battery backup.) Turn the monitor on. Unplug the battery backup power cord from the wall outlet. If the monitor remains on, the battery is holding a charge, supplying electrical power and the battery backup is working properly. If the monitor goes off, proceed to step four.

4 Charge the battery. Plug the battery backup into an electrical outlet and allow the battery to charge for 16 hours. This will fully charge the battery.

5 Test battery charge. Once the battery is fully charged, repeat step three. If the monitor stays on when power is interrupted to the battery backup, the issue is solved and the problem resulted from an incompletely charged battery. If the monitor turns off when power is interrupted, the battery within the battery backup is faulty and needs to be replaced.

6 Replace the battery backup unit. The unit itself is faulty. If the battery backup is under warranty, contact APC to request a replacement.

check the fan in the back .... try to replace if damaged

This sounds like a battery issue, test the battery by itself....

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.

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

sure as long as the APC is the same voltage.

It certainly indictes a problem with the APC unit a replacement bettry may or may not solve the problem. Do you really need one as you have an anti surge protector?

Often, it is an expired battery that will cause an issue like this. Since a bad battery renders the APC ups useless, it will usually display blinking lights to let you know that something is wrong. The software, if installed, will also help troubleshoot the problem. You find which battery you need from this site: http://batteryinternational.com/ups-batteries-apc-batteries.html
