A 9-volt battery is typically a single cell that provides a voltage of 9 volts. However, inside a standard 9-volt battery, there are usually six smaller cells (1.5 volts each) connected in series to achieve the total voltage. Therefore, while the battery itself is a single unit, its internal configuration is series.
The voltage is unknown, because it depends on the impedance of each battery. Certainly, damage is going to be done, because there will be excessive current.

The PP3 battery, commonly known as a 9-volt battery, is not a single voltaic cell. It consists of six smaller 1.5-volt cells connected in series to provide a total of 9 volts.
No
No, the battery will be overcharged and battery damage will occur if it is done.
No, a lead acid battery is a wet cell battery and a 9 volt alkaline battery is a dry cell battery.
It heats up very hot and may explode.
no
A 9 volt battery is stronger than a 1.5 volt battery because it has a higher voltage. The higher voltage allows the 9 volt battery to power more demanding devices and last longer than a 1.5 volt battery.
