Battery basics

Your car battery is essential, without it you would have no engine, no power and no lights. It’s important to understand a little bit about how your battery functions, and to recognise the most common signs of a battery that needs to be replaced.

There are some simple ways that you can help extend the life of your battery, as well as warning signs that can alert you to any potential problems.

Get Checked

At any Mitsubishi dealership, trained technicians can ensure your battery is in good working order, inspecting your battery’s health indicators such as its charging and cranking capabilities and you can easily purchase a replacement if necesary.

Regular replacement

Your car battery needs to be replaced around every four years even if it isn’t causing you any problems. There are sometimes signs that your car battery may need replacing, including:

Weak battery

Trouble starting

If the car battery is too weak to provide a sufficient voltage to the starter, you’ll hear a distinctive clicking sound and the engine won’t crank over. If the car struggles to turn over, but then the engine starts up without a problem, the battery is the likely cause.

Dimming headlights

Dimming headlights

If your vehicle’s headlights appear to be less bright than normal this could be a sign that your car battery needs replacing. If the headlights fade while the engine is being started or just after it has started then you should get your battery checked.

Auxiliary system

Auxiliary systems

If your auxiliary systems are not performing as usual, for example electric windows operating slowly or the dashboard lights being dim, it could be a sign that your battery needs charging or replacing.

Bad smells

Battery care tips

Here are some simple tips to help you keep your battery healthy and your Mitsubishi performing to an optimal level.

Clean and dry

Keep your battery clean and dry

Dirt and dampness can lead to a discharge and corrosion which will affect your battery’s performance.

Fully charged

Keep your battery charged

Leaving your vehicle stationary for long periods will affect your battery’s charge and reduce the life of your battery. It’s important to keep a battery fully charged by making sure that the vehicle is driven regularly.

Regular servicing

Poor engine condition can overload the battery and reduce its life. To ensure optimum performance your vehicle should be serviced by a Mitsubishi dealer according to the service schedule.

Avoid draining

Avoid draining

Avoid regularly using auxiliary systems, such as the radio or air conditioning, when the engine isn’t on. This will discharge the battery which will then require a recharge and constant recharging may shorten the life of your battery.
