The battery has internal problems and/or the vehicle is overcharging and is probably giving off explosive fumes. Don't do anything to cause a spark anywhere near the battery and take it to a repair shop asap for diagnoses.
No. It is dangerous. Get rid of it as soon as possible.
No, that looks as if the battery is damaged.
A bulging battery is an indication the is a short INSIDE the battery and it is getting overheated, causing gas to expand inside. It could explode on you.
The bulging is caused by gassing. This is caused by overcharging or by a short circuit inside the battery. The acid inside the battery is turned to gas and it expands the sides of the battery.
no
If your car battery smells like "rotten eggs" then your battery is producing excessive hydrogen and is probably not safe. Please check you cars' charging system and make certain that the battery is not being overcharged. The battery can possibly explode.

Yes, if the battery is weak it will not provide enough electrical energy to properly operate the starter.

Disconnecting Auto Battery Terminal ConnectorsYes, it is safe to disconnect a "car" battery while it's raining, IF you do it properly.When disconnecting a vehicle battery, raining or not, ALWAYS disconnect the NEGATIVE [--] terminal first, and when reconnecting, always connect the NEGATIVE terminal last.
a car is only as safe as you operate it. a bigger car will always provide you more protection and is more likely to be seen by other drivers. however, a smaller car might be easier to avoid a collision with.
That would tell me that your battery is not dead because you do not need the car turned on for your brake lights to operate
disconnect battery cables
If you know for sure that the alarm is functioning correctly, but the key-fob doesn't operate - either the fob is faulty or the battery is flat. Replace the battery - if the fob operates the alarm, then the battery was flat. If the alarm still doesn't operate, then the fob is faulty. You can always test the battery with a multimeter - although you may have to dismantle the remote to get at the battery !
