How would I confirm the ups battery is dead? Do I unplug the UPS while using it to see what happens? Last time the battery timer in seconds would go down very fast. So now it might just go off instantly?
Also I have the UPS on the floor and the back of the UPS facing me as I have it under my folding table. So if I turn the UPS around, is it possible it isn't even on and there is no power at all because of the battery?
But is there any issue still using it as is but just using it for the 6 surge outlets? Before the 6 battery+surge outlets stopped working, someone had told me even though my ups battery is worn out because unplugging it from the wall outlet has the minutes go down really fast, that person said you could still use it as a surge protector without any issue. It just wouldn't have any battery backup though. But now the situation is difference since the battery is dead? But can you still use it like a surge protector now? Or do you have to replace the battery and what about the wiring fault? Again the thing is I have no idea if that wiring fault indication had a red light back then even. If it was, I might not even had noticed it until recently. I mean I know there was that red button in the back of the UPS but just never recall it being light up like it is now etc.
The best way to test a battery is with a multimeter. I recommend everyone who has to play with electronics, or even who is unsure about their building wiring get one. A cheap one can be had for $20.00 or so. If you do get one, make sure you understand how to use it, esp if you test any AC voltage sources, such as electrical outlets.
Each battery can be removed and tested separately. Generally, UPS batteries are 12V and so each battery should measure at least that using the DC Volts setting. Make sure never to touch the battery terminals with bare hands as those are high current batteries and you could get a shock.
Alternatively, you can call a shop that sells UPS batteries, and ask them if they could test your batteries and/or install new batteries and do a test. Tell them you don't want to have to pay for them unless the UPS works. Most shops I've dealt with are quite reasonable that way.
Again, surge protection is not going to work properly without a grounded outlet. Is it even legal in your state to have ungrounded outlets? They are, of course, a serious safety (electrocution) risk.
