Battery
The battery itself can not, but, as with any battery, the contact of positive & negative contacts can cause a spark which may constitute an ignition source.
No, at most it is damaging property.
Probably alternater if the battery is less than 5 years old, may be the battery, may be both, may be neither.
Alternator may be defective, or connections at battery may be corroded or loose. The battery itself may also be defective.
If you reverse the connection of the battery charger you will discharge the battery. You may be able to correct the connection and charge it properly, or the battery may be ruined.
The alternator may not be recharging the battery .
That did constitute a valid request.
Can you constitute your actions.
Impossible to say. The battery may explode or it may not. You may destroy the battery or it may survive. Your main fuse may blow or it may not. You could have other electric damage or not.
The same act can constitute several different crimes based on the specific elements and legal definitions of each crime. Different crimes may require different mental states, intent, or circumstances. For example, two crimes such as assault and battery may stem from the same act of hitting someone, but the charges will vary based on the level of harm caused or the intent behind the act.
You need to add electrolyte and charge the battery. You will then know if it is ok. It may be fine, and it may not be.
