Whats really concerning about the gas is its very poisonous when breathed in.

Add to that the gas is flammable too. Hydrogen Sulfide gas doesnt easily disperse either.

Even a few breaths of it can cause confusion and a loss of taste and smell. This makes it potentially deadly if the main sense smell that would warn you of this danger is now not working correctly.

Even providing ventilation may not be enough to remove a pool of gas. As its heavier than air, it may still sit below a window level and not be dispersed if indoors. Always best to open a garage door if you suspect its present.

The metal parts inside the engine are also spinning faster due to increased pressure on them with an increase in RPMs, too!

One Reason When Your Car Battery Should Smell Like Rotten Eggs

Now, if youre really into battery maintenance, there is a thing called equalization or desulfation. Both of which are basically a controlled overcharge to either bring the individual cells to an equal state or to agitate and break off any sulfation that has occurred on the plates.

Many but not all smart chargers have this feature and it also is sometimes called recovery mode.

Smart chargers will carry out the process automatically without need the need to intervene. However, this process can take up to 8-10 hours with some models which Im just not a fan of. I dont care to have my battery boiling for that long and risk the heat evaporating all of the electrolyte, bulging my battery, poisoning my household or worse.

If you monitor the process with a voltmeter, youll see the process get well into the 16.5-volt range. Anything over 14.5 or so is getting into the overcharge range. 16-volts and higher and youll hear the electrolyte boiling from 30 feet away.

When Ive done a desulfation mode process, I stopped it after 30 minutes. You can do what youd like though. I just dont like the risk and I no longer perform it as a maintenance measure. Some people swear by it, youll just have to do your own research and weigh the risk to reward ratio.
