What causes the car battery to need replacing?

A car battery can fail for a variety of reasons, and understanding these causes makes it easier to spot problems early.

One of the most common factors is simply age. Most batteries last between three and five years, and as they get older, their ability to hold a charge naturally declines.

Corrosion is another frequent issue as when the terminals become coated in a crusty residue, the electrical connection weakens, making it harder for your car to start.

Weather can also play a significant role in needing a car battery replacement.

Both extreme heat and freezing temperatures can put stress on a battery’s internal components, shortening its lifespan.

In many cases, simple maintenance can ensure the battery is in full working order.
