Do Car Batteries Come Charged

When you are out of the station for a long vacation, you will probably park your car in the garage. When you return home after a few weeks, there are chances of you finding a car with a dead battery! Do car batteries come charged? This is a common question that all the new purchasers spend some time to clarify when they want to replace a dead battery. 

A car battery is a key factor in starting the electrical motor responsible for the internal combustion engine. The battery is the energy provider to the vehicle’s various accessories when the engine is stopped. The air conditioner, sounds, wiper, headlights, extra lights installed, and airbags are some features powered by the electricity provided by the battery. The usual life span of a car battery is between 3 years-5 years. When it is time to change the battery, it will show some functional issues in the car. 

Do Car Batteries Come Charged?

When running, the alternator recharges the battery by converting mechanical energy to electrical energy. When the car is being parked for a long period, tools like the clock, security alarms, radio, interior lights, door lights, and trunk lights continuously drain the battery power.

There is no way to regain power as the vehicle is parked. Thus, this parasitic drain will make your battery dry within two weeks. Therefore, if you are not using the car for some time, make sure you start the car at least once a week. It is also a wise method to disconnect your car’s battery when you cannot use it for several weeks or months. 

Finally, when it is time to replace your battery, you will have to jump-start it as the battery does not perform. According to specialists, jump starting can cause damage to your car if it is not done following the exact technical procedures. It is a good idea to move on with a new battery once the battery health decreases to 40 % or lower rates. Do car batteries come charged? This is the next probable question you will be searching around regarding an emergency replacement.
