But at the beginning, the battery is the sole component that starts the engine when you insert key in the ignition. A weak battery will take more time to start the engine, so the engine will crack quite slowly.

It means the battery is too low on power.
Issues With Electrical Components

A car battery is nothing but a blend of different chemicals cased in a box. As a car’s battery is exposed to excessive heat or cold, the case may be swollen or bulged. If your car sits idle during winter, the battery may freeze and eventually be dead.
The standard lifespan of a car battery is 4-5 years. But this may vary depending on the length of car battery maintenance, and exposure to heat and cold.

As soon as you detect such a stench under the hood, have the battery removed and have the surrounding components checked, to see if the sulfuric acid has done damage to any other parts of the engine.
