No it cannot.
Install a 3 volt battery and forget any modifications. It will not operate on 12 volts.
No, you will need two 12 volt batteries connected in series to give the 24 volts necessary to run the pump. It will not run on 12 volts.

The capacities of batteries are rated in amp hours. The higher the amp hour rating of a battery the longer the device connected to the battery will operate. Depending on what the connected load draw in amps is, will determine how long the connected device will operate.
Charge it with a 12 volt battery charger.

A 12 Volt deep cycle marine battery.
12 volt
Yes, an automotive 12-volt battery can be used to run a 12-volt generator, as both operate on the same voltage system. However, it's important to ensure that the battery has sufficient capacity to handle the generator's power requirements. Additionally, consider the battery's condition and state of charge to ensure optimal performance. Using a battery not designed for sustained discharge might lead to reduced lifespan or efficiency.
No, a 12 volt charger will overcharge a 8 volt battery and destroy it.
