When does my Mercedes battery need replacing?

Unfortunately, it’s not as easy as waiting for a date or mileage to come around the corner. But there are a few tell-tale signs that you might be due a new Mercedes battery:

• Dashboard warning lights could alert you to battery problems. Look out for battery or engine warning lights and get your battery checked if either flash up.
• Trouble starting your Mercedes can be a sign of an ageing battery. Older batteries become less efficient, producing less power when you start the engine.
• Electrical problems such as dimming lights and unresponsive windows also point to battery issues, often happening just before it goes completely flat.

Can I get my Mercedes car battery tested?

If you have one, you could test your Mercedes battery at home with a multimeter. But our free battery test service is likely to be a quicker, easier and more reliable option!

We look at crucial factors like the voltage, start capacity and condition of your battery to make sure it’s running as it should. Checks like these stop small problems from getting bigger – and they’re more important now with all the in-car technology modern cars rely on.

And if your battery is past the point of no return, we can arrange a hassle-free replacement in just a few minutes.

What battery does my Mercedes need?

Choosing the right battery for a Mercedes car will depend on what it needs to power, and your owner’s manual should have the info you need. (Or you could save yourself the effort and use our instant battery search tool at the top of the page.) Our battery test technicians can also steer you in the right direction.

Whatever the case, we’ll have you covered. We stock these four battery types:

NAPA AGM

NAPA absorbed glass mat (AGM) batteries are sealed, lead-acid batteries that suit micro-hybrid cars. They’re designed with fuel-reducing technologies, like stop-start systems and brake energy regeneration, in mind. Their fibreglass mat is there to absorb any leaked sulphuric acid.

NAPA AGM batteries last longer while providing fewer CO2 emissions compared to advanced flooded batteries (AFBs).

NAPA AFB

AFBs are the next evolution of standard wet flooded batteries. You might see them referred to as enhanced cycle mat (ECM) or enhanced flooded batteries (EFB).

These batteries are designed for vehicles with start-stop technology and provide better cyclic performance.

NAPA PLUS

As the name hints, NAPA PLUS batteries boast 30% more power than standard batteries and have a longer lifespan too. As well as diesel engines, they’re ideal for cars with satellite navigation systems, media players and other in-car electronics.

NAPA PLUS uses state-of-the-art labyrinth technology to guide water back into the battery, keeping the fluid level healthy.

NAPA

NAPA’s original flooded lead-acid battery is compatible with most vehicles, including Mercedes. Calcium/calcium technology provides greater battery life, high-temperature resistance and reduced water loss. Their lead plates react with battery acid when fully charged to store electricity.

What’s a typical Mercedes car battery price?

There’s not one set Mercedes car battery price. Your final spend will depend on your model and the type of battery you need to power it. Whatever the case, our price promise makes sure we’re never beaten on price - so you won’t find the same product, including fitting and/or delivery, cheaper elsewhere.

Our battery search tool will give you a quick idea of what your ideal Mercedes car battery will cost, including options for fitting and disposal. With prices starting from just £61, you don’t need to break the bank. What’s more, our flexible payment options allow you to spread the cost of a more premium battery if that suits you better.

Do you offer mobile battery fitting?

We do! If it’s not convenient to visit one of our 235+ branches across the UK, we’ll come to you at home or at work.

You can book and pay for a mobile Mercedes battery replacement online and choose an ideal time and location. It’s an especially handy option if your battery has completely run out of juice.

How long will my Mercedes battery last?

It’s tricky to predict when you’ll need a new battery, which is why some people get caught out when theirs goes flat. Battery lifespan ultimately depends on how power-hungry your Mercedes is and how you drive it, as well as external factors like extreme weather conditions.

Your original Mercedes car battery will likely have come with a manufacturer’s warranty, so check your paperwork from the purchase. When it comes to your replacement, all our batteries are guaranteed for a minimum of four years for your peace of mind.

• NAPA battery range: four-year guarantee
• NAPA Plus: five-year guarantee
• NAPA AFB and AGM ranges: five-year guarantee

How do I get rid of a Mercedes car battery?
