When cleaning a standard 12 Vdc car battery's terminals, it's a common practice to pour a mixture of baking soda + hot water all over the terminals. The water can spread and effectively short out the battery in two ways:
- Positive terminal to negative terminal
- Positive terminal to car chassis (to negative terminal)
Why does this not cause major problems (ex: explosions)?
Quora answer: What happens if a car battery short circuits?
YouTube video: Shorting Out a 12V Car Battery
Indicates that shorting a car's battery can be quite detrimental.
You can see the water connects the battery's positive terminal to the negative terminal. In my mind, this should create a short circuit, as the water is effectively shorting the positive and negative terminals. However, nothing bad seems to happen. Why is this?
Says water isn't all that conductive, but I am not sure if I agree with this vague statement.
