When a battery is put in water, it can cause a chemical reaction that may release harmful gases or cause the battery to leak. This can be dangerous and should be avoided.
It Wont fit in o-o
The battery would lose its acid.
The battery will melt over a period of a week. If you put a mold around the battery you can make a donut during this period of time. Very tasty (I tried it!) jerk
Nothing as long as it was a 12 volt battery.
If you put a firecracker in a pie it will explode, I have experience.
When you put a battery in water, it can cause a chemical reaction that releases hydrogen gas and can lead to the battery overheating or even exploding. This is because water can act as an electrolyte and allow the battery to discharge rapidly, which can be dangerous. It is important to never put a battery in water to avoid potential hazards.
My question is why would anyone do this? But since you asked. It will ruin the battery.
