How long does a car battery fitting at home take?
It will usually take around 1 hour for a mobile mechanic to carry out a car battery fitment at your home or place of work.
The timing can fluctuate due to the geographical location of where the fitting takes place, and where the battery sits within the car.
If there is any further damage to the surrounding area, then it could take a bit longer.
How long will a new car battery last?
Car batteries normally last 3 to 5 years - but this can vary due to many factors - including level of car maintenance, driving style, where the vehicle is kept when not in use, and the vehicle/battery type.

What causes the car battery to need replacing?
One of the most common reasons for a car battery replacement is age. Most batteries last between 3 and 5 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.
