Now it says:
battery.runtime: 1170
The display on the UPS fluctuates between 16-19 minutes.

ups.load says 30 constantly and The display on the UPS says 30% so I 
think that is correct.

How you find out your battery was manufactured in 2012?
I did buy an after market battery.

How would I know if is the UPS?
Maybe I shouldn't spend any money on the current one and I should just 
buy a new one.
