If your car engine is the heart of your car, then a battery is its brain. It is vital to check your car’s battery health regularly and keep it updated. If your car’s battery is not working efficiently, you may face serious problems, and it could affect heavily on your car’s overall health as well.

How long should a car battery last?
The lifespan of a car battery depends on several factors. However, if you are living in colder parts of the country, you can expect your car’s battery to be workable for a maximum of four years. On the contrary, in places where hot and humid weather is usual, the lifespan of a car’s battery drops down further to a maximum of two years. One of the major reasons for this is, during hot weather, the liquid inside the battery evaporates, which weakens the battery.
Moreover, chemical reactions can also wear off the battery sometimes, even if you live in ideal weather conditions.
What are the major causes of a dead battery?
As stated above, multiple reasons can result in your car’s battery breaking down. Apart from weather conditions, if your car is parked for a long period and is not used, it may also cause the battery to breakdown. A major reason behind this is that your battery doesn’t get time to recharge.
A car’s battery recharges itself when the car is moving. This is why when you take your car to drive on a highway, the drive becomes smooth and easy as you cover the distance. On the other hand, the shorter time your car is on the road, the lesser time your battery gets to recharge itself.
Apart from this, if the charging system or starter motor becomes faulty, it may also affect the health of your battery. Moreover, other reasons for a faulty battery or battery failure may include incorrect battery type or incorrect size, loose, worn-out, or dirty terminals, etc.
