Battery Out-gassing
Yes, vehicle batteries are usually of the lead-acid type, and these batteries give off hydrogen gas while they are either being discharged, or charged.
Hydrogen gas is a colorless, tasteless, and odorless gas, is highly flammable and when mixed in proper proportion with oxygen in the air, hydrogen can be explosive.
Smoking or any arc/spark within the hydrogen-oxygen gas envelope, or an internal spark inside the battery, can cause a massive explosion throwing sulphuric acid and disintegrated battery case plastic for some distance. This explosion of the battery out-gas can do very serious bodily harm, and has been reported to have resulted in deaths.
Therefore, it is critical that all possible safety precautions are followed when working with, on, or around vehicular batteries. Most modern auto batteries have decals on them listing the major hazards and recommended precautions.
Weak battery and no gas can both cause a no start.Weak battery and no gas can both cause a no start.
Car battery vapor is hydrogen gas and is extremely explosive.
Hydrogen gas.
That depends on what effect is desired; If you like to breathe, it is a useful gas; If you prefer that your car (or whatever) not be rusty (oxidized), then it is a harmful gas.
Car battery polarity can only reverse if the battery is completely dead and then charged with the neg. and pos. leads of the charger are reversed. This is very dangerous as hydrogen gas which is given of buy a dead battery may explode and cause personal inguiry.Likewise if the car's battery cables are accidently reversed while the battery is dead.

Hydrogen
A hybrid car is a car that runs on battery and gas. It uses standard unleaded regular gas.
An auto battery does emit hydrogen gas when it is being charged or discharged but it does not contain gas per se.
Hybrids are a gas powered car that uses gas to charge that battery, which drives an electric motor.
gas or a battery charged car makes a car run.
