Assuming a typical North American residential service, Voltages of 145VAC are possible when the Service Entrance (Source of Electrical supply) has lost its neutral (Grounded Current Carrying Conductor)
Especially in older installations, the lose of the 'Neutral' can cause voltage to swing from 0vac to 160V (The highest I have ever seen personally). The reason the voltage 'floats' is because the system has lost it's neutral reference from the power company's transformer.
The condition is very hazardous and can/will severely damage anything connected to the system.
It is strongly recommended that you disconnect any devices and have a licensed electrician inspect your service entrance immediately. Typically the problem is customer equipment side, and you will be charged. In the event the power company equipment is responsible, they could be (possibly, varies depending on location and power company) responsible.
In my personal experience, this condition is caused by either a poor connection at the weatherhead, or lose/corroded connections either in the meter base or in the main breaker panel.
Typically, customers are responsible for their respective service entrances up to the weather head. Which is the mast and wires above the meter base, all the way to the connections in the drip loop.
My outlets have 132 volts in the kitchen! And 130 at the shop witch is 300 ft away ! Is this to much ! And transformernot cutting enough
A reading of 145 volts is high. The first thing that I would check is the accuracy of your meter. Check the voltage reading at different locations for example, friends homes, to see if the reading is still high there. If it is check your meter reading against another meter. If you are sure that your meter and reading is correct then call the utility company and get them to check the voltage for you.
145 - 120 = 25 25/120 x 100 = 21% increase
(145 mm) x (90 mm) x (120 mm) = 0.413693434 US gallons
You would have to know the voltages of the battery and the UPS to know for sure. For example if the UPS' output is 120 volts, then it is capable of 5 amps of output. If the battery is also 120 volts, then it would take the UPS 29 hours to fully charge the battery. However if the battery was rated at 220 volts, then the UPS would never completely charge the battery. The source of the charging voltage must exceed the battery's voltage in order to fully charge it.

maybe you should raise it to $145
The LCM of 25, 120, and 145 is 17,400, which is the multiple of the highest power of prime factors from all numbers (25 = 52; 120 = 23 x 3 x 5; 145 = 5 x 29). (23 x 3 x 52 x 19 = 2 x 2 x2 x 3 x 5 x 5 x 29 = 17400).
The sum of the factorials of digits of a number is equal to the original number. Ex: n=145=> 1! + 4! + 5! = 1 + 24 + 120 = 145

Using a 120 volt bulb in a 130 volt socket may cause the bulb to burn out more quickly or not function properly. The higher voltage from the socket can lead to a higher current flowing through the bulb, which can damage it or cause it to fail prematurely. It is always best to match the voltage of the bulb with the voltage of the socket for optimal performance and safety.
Yes it coudl damage equipment. Check voltage rating on equipment. However, there should be an adjustment somewhere on the generator to set the voltage properly. Also make sure your meter is calibrated. Check a known voltage source such as an outlet and compare readings.
