What does a car battery do?

The car battery is responsible for powering all of the electric components in your car. As well as the lights, stereo, windscreen wipers, etc. it is also responsible for powering the ignition system that starts your engine and keeps it running.

How often should a car battery need replacing?

A car battery is to have an expected lifespan of between 4 to 6 years. This is dependent on several factors, for example, the quality of the battery, weather conditions, vehicle type, driving habits, and vehicle type.

The law, vehicle regulations, and your MOT

The physical condition of your battery will not cause your car to fail an MOT, but if the car won’t start, run or operate the electrical components properly because of your battery, then that will. What happens when we replace your car battery?

  • Our efficient and fully qualified mechanics will inspect your battery for correct operation, signs of corrosion and will be load tested to ascertain its ability to retain charge.
  • Wherever required your battery will be replaced and you’ll be advised of any other connected or associated problems arising from its malfunction.
  • You will also be advised of any other parts, for example, the cables, that may need to be replaced for the best operation and health of your vehicle.
  • Once the battery has been replaced, our mechanics will test it thoroughly to ensure the correct running of your car and make any adjustments required for its premium operation.

What causes a car battery to stop working correctly?

Your battery is continually being charged by your car’s alternator while driving, so it’s only through damage or that it has reached the end of its operational life, that it will fail to hold its charge. On occasions when there has been excessive electrical use without your battery being recharged, your battery will be drained. A drained battery will only require a recharge unless the battery is faulty and its failed operation was instrumental to the drain. After prolonged use, a car battery can leak the acid that holds the electrical charge. This liquid will turn to a white or bluish powder where it dries, so is fairly easy to spot. Eventually, a battery will simply reach the end of its life. At this point, it’s time to organise a replacement.

Symptoms of a malfunctioning car battery

If your car won’t start

If your car doesn’t start when you turn the ignition switch, especially when the engine doesn’t make any attempt to turn over, your battery could be flat.

None of the electrical components work

If the lights, fan, radio or any other electrical components in your car don’t turn on or operate, then your battery could be drained or damaged. The terminals are corroded If the terminals (connection points) on your battery are corroded, then your battery is likely to be damaged or worn out.

Your battery has powdery deposits on it

If there are white or blueish powdery deposits on any parts of the battery, this is a sign of acid leaking and incorrect operation of your battery.

How often should I drive my car to keep the battery charged?

It depends on how far you drive and your driving style. Running your car for 20 minutes per day could be enough to keep an adequate amount of charge on a healthy battery, but that could prove unhealthy for many other components in your vehicle.

You should be able to keep enough charge on the battery if you drive it a couple of times a month for 10 or 15 miles, but again, it depends on your car. Some might need to be driven every week, or even every couple of days.

Does your car run better with a new battery?

It shouldn't. Your battery's job is to start the car. Once the vehicle is running, the battery shouldn't impact its performance at all. However, the battery does have some impact on the performance of the alternator and a few other components, so long-term, an old and weak battery could affect the running of your vehicle.

What should I do if my car battery is low?

If you have difficulty starting your car, or you spot any tell-tale signs that your battery has lost its charge, then it's time to charge your battery. If your car fails to start, you'll need to jump-start it with another car or charge the battery from the mains.

Depending on the suspected cause of the discharge, you may need to replace your battery or explore the reasons it isn't charging properly.

How do I know when my car battery is fully charged?

A healthy battery with a full charge should start a car almost immediately. If the car struggles to start or there's a clicking noise instead, the battery charge is low or flat.

You can check the charge on your battery with a multimeter. A healthy battery should measure 12.6v or above. When the engine is running, it should read between 13.7–14.7v.

A simpler test is to start your car and turn on the headlights. If the lights operate their usual brightness, then there's plenty of charge on the battery. If the lamps are dim or fluctuate as you press the accelerator, then there may be problems with your battery or your alternator.

Why does my car keep dying with a new battery?

The most probable reason is a broken or poorly functioning alternator. Other components that can affect the charging of your battery are badly fitting or loose belts and tensioners.

Having said that, there are many simpler reasons for a reoccurring drain. There could be an electrical component running without you spotting it (a radio, or parking or interior lights left on). A not quite closed glove compartment or boot could mean that there's a light left on that you stand little chance of spotting.

Why does my car battery keep losing charge?

A car battery can lose its charge for many reasons. It could be the end of its life (around 4 years), there could be a parasitic drain continuously depleting the battery's charge, or there could be a problem with the vehicle's electrical system.

Other possible causes are loose or corroded cables, predominantly stop-start or short journey driving, extreme temperatures, or leaving lights and other electrical components on by accident.

Can I drive with a bad battery?

Probably, but it's not recommended. If you can get your car started with a flat or low charged battery, then it could run as normal. The problem is getting it started again after you stop.

A battery that has lost its charge because of an accidental event may recover through driving. If the drain was caused by faulty components or dying battery, it's imperative to get the problem repaired or have the battery replaced.

Can a completely dead battery be recharged?

If your battery fails to get any reaction from your car engine, then it could still be charged to return to its normal, healthy level. While your alternator can do this, if you jump-start the vehicle, it's not the job it was designed for.

A dedicated battery charger will deliver a safe amount of charge over the correct duration. They are designed to protect your battery while topping it back up. Connect the positive terminal before the negative, and when you switch your charger on, be sure to select the slowest charge rate for severely depleted batteries.

Does leaving a car running charge the battery?

Yes, although it's not considered the best practice as it could cause harm to other components of your car. Also, the alternator responds to the engine operation, so just ticking over will reduce the charge to a trickle and have little impact on your battery. Driving the car or using a dedicated charger are much better options.

Can a battery be too dead to jump?

Yes. A car battery can become so flat or defective that it won't jump-start. This could be from stratification, sulphation or cell reversal. In most cases, though, a jump-start will get a car with a flat battery started, and running the car will begin the process of recharging the battery.

Can I drive my car after jump start?

Yes, you can. It's a good idea to allow your car battery to build some charge before you do, though. The problem isn't with the performance of the vehicle, but what happens if you accidentally stall. Your battery may not be charged enough to restart the car and leave you stuck in traffic.

Do I need to replace the battery after jump start?

No. A battery can lose its charge for a multitude of reasons. Not all of them will mean the battery has reached the end of its life. If there is no apparent reason for the battery to have lost its charge, then have it tested, along with the alternator, to find out the reason why.

How long should I drive my car after a jump start?

The longer you drive, the more charge your battery will receive, however, this isn't ideal for your alternator. The best option is to charge the battery to full, on a slow charge, with a dedicated charger.

30 minutes driving at over 2000RPM should be enough to put enough charge back on the battery to start the car again. An hour of driving should get the battery back up to an almost normal level of operation.

How do you charge a car battery while driving?

During normal driving, the alternator 'surface charges' your car battery. Even though the alternator adds charge to a flat battery during driving, and can top it up to its typical levels, this isn't what it was designed for and can cause strain on the alternator and affect the lifespan of your battery.

Charging a flat battery with a dedicated charger is the correct option for both battery and alternator health.

Why my car battery goes flat overnight?

If your battery loses charge when parked overnight, it's likely one of three causes. The first is that it has reached the end of life and refuses to hold its charge. The second is a parasitic drain. This means that one of your car's electrical components is using the battery's charge without you realising. The final most-likely reason is a problem within the electrical system.

Can I replace car battery myself?

Most competent DIY mechanics will have very little trouble replacing a car battery. You may experience some issues, as certain modern manufacturers require a new battery coding to their energy management system, or if the battery location is difficult to access. Remember, a lot of electrical components rely on your car battery, and may require resetting after being disconnected.
