Remove batts, Check battery connector, fuse and batt volts, if you have dummy load (car headlight etc) check batts are working and measure voltage under load.

Also check if UPS needs to be told there are new batts read manual or check support for maker.

Let me know what you find, hope this helps

I take the 4 screws out of the bottom of the Powermust the unit opens but appears to be hinged at the back so I can't get access.


You don't need back side.
The battery locates at the front.
Carefully get out forward case (with button), and you will get access to battery.

In my home, it was a fault in ilumination and the UPS isn't ringing but is always with the red light on What can I do? PS: Sorry my english but I am portuguese


The red light means that it is being discharged or is low on battery power/it's not recieving power from the wall plug. Maybe the UPS needs to be charged. While the power is on at the wall plug, switch off the power to the UPS then you should get an orange light showing that it is being charged. Switch off your computer for a while, aftyer about 12 hours it should be fully charged.

Your rating of this solution is much appreciated.
Thanks.
