my car alarm battery died and why is it that the battery of the car is dead now?
The battery for the car powers everything, from the headlights to the radio to the car alarm. If you left a light on inside your car, left the headlights on, or the alarm went off for a long period of time, then it makes sense that the battery would have died because it powers all electrical things that are not powered by gasoline. The car won't start because it requires a spark to light the spark plugs that light the gasoline which power the engine. If you jump start the engine, you will be able to go places, but once you turn off your car, you will need another jump. You will need to get the battery replaced.
