Although a car battery can last for at least five years (when properly cared for), it will usually become worn and inefficient within three years. This reduced lifespan is due to external factors like cold, wet weather – a normal occurrence in the UK. Commuting in congested urban traffic also contributes to decreased battery performance. Much like your smartphone or computer’s battery, your car’s battery deteriorates with each “charge” / engine boost. Not replacing your car battery within the three-year mark often leads to unreliable performance and frequent stalling – which is often a major inconvenience.

Preventative care & car battery warning signs

According to The Telegraph, battery issues cause over 66% of vehicle recovery calls. Below are some red flags to spot and tips on how to maximise the lifespan of your car’s battery:

  • Take longer journeys. Frequently starting and stopping your car, due to journeys of 10 miles or less, often greatly reduces the charge of a car’s battery.
  • Watch out for corrosion. Routinely check your car’s battery to make sure connection points remain clean.
  • After turning off the engine, avoid running the radio and other electronics. Since the engine charges the battery, using electronics while the car is off usually shortens the lifespan of your car’s battery.
  • Ensure the electrical system / alternator is in good working order. If in doubt, hire a mechanic to check the charging mechanism.
  • Read your car’s manual and use a battery tester. It’s always important to consult your car’s manual before inspecting any part. After determining the location of your car’s battery and correct position of the charging terminals, use a simple battery tester found at most car accessory retailers. This device should provide a good indication of the battery’s health (Carbuyer).

  • Replacement process

    Replacing your car’s 12V battery may seem like an easy task. However, with battery prices ranging from £50-£200, doing it yourself doesn’t save you that much. Not only must you follow careful instructions to properly replace a car’s battery, but you could miss other preventative care opportunities. During the installation process, your mechanic may find unknown issues which could make you fail an upcoming MOT test. Not passing an MOT can result in huge fines – up to £2,500.

    The Sunday Times provides step-by-step instructions on how to replace a car’s battery. To check if a new battery is correctly installed, you’ll have to wait for it to charge and use a battery tester. This process can be time consuming. You’ll also need to check to see if it’s properly fitted – which is an easy mistake. If any of these steps aren’t followed correctly, you risk prematurely wearing the new battery or having a car that won’t start.
