You can wire two 12 volt batteries in series... Connect negative of the first battery to positive of the second battery. That common connection becomes ground. The positive of the first battery becomes +12, and the negative of the second battery becomes -12. However, do not expect to be able to charge the second battery in a system designed for only one battery, such as in an automobile.
Yes, normally, assuming it's 60 cycle (hertz) AC. In the USA, 110 volts as such is no longer used, it's really 120 plus or minus about 5 volts everywhere.
+24 volts is not normally used for telecom equipment. -48 volts is the usual value. 48 was chosen as a compromise between safety and voltage/power efficiency. Minus was chosen over plus to manage corrosion effects of cabling in underground installations.

12 volt standard, 24 volt optional.
If you are only getting 118 volts on a 120 volt outlet, it is within an acceptable range due to minor fluctuations in voltage. It may not necessarily indicate a problem with the outlet, but if you consistently experience voltage drops, it could be due to issues with the wiring or electrical connection that may need to be inspected by a professional electrician.
