What does a car battery do?
Every car needs a battery to operate. What a car battery does, it helps drive the car’s engine from assisting with engine heat, making the headlights and rear headlights work, activating the stereo system, or even helping the windows to move up and down.

How much does it cost to replace a car battery?
First, the new car battery has a short life span of 2-5 years. Most batteries for new cars with a 2 year warranty can be replaced without costing you a single cent. This is because the battery is charged and charged by a device called an “alternator” in the car. The alternator helps to convert all the physical energy in a car engine into an electric motor that charges the car battery.

Second, for the reasons mentioned above, a new car battery does not need to be replaced immediately. However, if it has expired or provided signs of replacement, go to a car mechanic who will inspect it and replace it if necessary. When the time comes to replace it, you should not worry as the cost of replacing the battery is very low. The average cost of replacing a new battery is estimated at $ 150, which includes replacement work for most cars out there. You can reduce that cost by purchasing a battery at a battery store and replacing it yourself, if you know how.

Other signs of low battery
Before you need to replace your car battery, the battery shows some signs before the exhaustion which is a good indicator. Preliminary features may indicate that a “test engine” light is coming. This means that the car battery is either running low or dead soon. Always check the battery life from time to time so that you do not get stuck in the middle of a car crash.

Here are some signs that the battery is running out:

• The engine starts slowly
  Over time, the parts inside the car battery begin to malfunction. When this happens, the battery will take a long time to create charging, resulting in a few seconds to start the engine.
• Blurred lights or electrical problems
  Car battery provides power to all of your car’s electronics, from the head and tail to the stereo system or to the dashboard computer. If the battery is completely discharged, you may run into problems with electronic devices because they will not operate at full power. If you add more power to the car as a charger for your phone, there is a good chance your battery will soon run out.
• Check engine light
  In most cars, when the light of the test engine appears to be on, it may mean a few things but it usually comes on when the battery is running out. Take the battery of your car to a mechanic to check if it is fully functional or not. If not, replace it with a new one and the cost of replacing the battery will not be much in your pocket.
• Bad smell
  If the battery is damaged or defective, this may result in gas leaks. If you have ever smelled rotten eggs when you open the engine door, a leaky battery is a sign. Take it immediately to test or replace it before you create car problems.
• Rusty terminals
  Some time after buying a new battery, you may notice that there is something white on the car’s metal parts, especially near terminals. If so, then you have a rust problem. Both terminals may be damaged which could lead to problems with the battery voltage and trouble restarting your car.
• Inverted battery case
  Hot weather may not affect your battery life that way but cold weather may affect battery life faster than you think. Severe weather conditions may cause the battery case to break or swell. If your battery is not rectangular, it may not be working properly.
• Old Battery
  If you experience any of the above symptoms, then try to remember when your car battery was last changed. As mentioned earlier, a good car battery lasts for 2-5 years. Climate change, driving habits or electrical requirements can all affect the length of the battery life or its shortness.

It is always a good practice to check your battery performance and check it whenever you are down to the repair shop. Try changing it if you are experiencing any of the above symptoms. Also, do not be afraid to replace your battery with a new one if needed, and remember that the cost of replacing the battery will always be lower than you think.
