when to replace a mercedes-benz battery

How much is a Mercedes-Benz battery? This is one thing many car owners don’t necessarily think about when they make the decision to buy a Mercedes. But after a few years, when the battery is beginning to show signs of deterioration, it becomes a more important question. After all, the battery is one of the most critical parts of any car. Buy the wrong Mercedes battery and you may end up paying over the odds for it. You might even be sacrificing not only your car’s performance, but your own safety as well.

Interestingly, you will get a huge range of answers when you ask various battery distributors how much a Mercedes-Benz battery is. The price can come in at anything from £315 to as high as £1,248. That’s because there are a host of factors that can influence the price of a car battery. The most important is the kind of battery you’re buying.

AGM Batteries for Mercedes-Benz

Experts usually advise owners of Mercedes-Benz cars to opt for AGM batteries, which is unsurprising as most Mercedes are, by default, equipped with an AGM battery at point of sale.

AGM batteries have a relatively long life even if you maximise their deep cycling capabilities. They can provide high amounts of current any time you need it. They do have higher manufacturing costs than other types of batteries, and therefore cost more for the car owner to buy, but this is outweighed by their long lifespans.

They also perform better and last longer than their counterparts in extremes of temperature, whether during long, hot summers or freezing cold winters. In this respect too, they will outperform more basic kinds of car batteries, so when you’re asking how much is a Mercedes-Benz auxiliary battery or main battery, don’t be surprised if the price you’re quoted is much higher than if you were looking for a standard lead-acid unit. You pay more, but should also get up to twice as many years’ use out of your purchase.

Other Factors That Affect Battery Price

Another factor that can hike up the cost of getting a new Mercedes battery is the charge for labour if you ask a garage to fit it for you. This is one area where it could pay to shop around, because some service providers can end up quoting extortionate prices for the battery plus labour costs.

If you intend to go down this route, ask any garage or dealership you’re thinking of using for a breakdown of their charges so you can clearly see how much the battery and labour each cost.

Importance Of Buying The Right Batteries

The next time you’re asking how much is a Mercedes-Benz C300 battery for your car, don’t just opt for the lowest quote, though. It’s more about getting the right battery at a reasonable price.

Why is this important? Mercedes admits that one of the most common reasons why their car owners have to call for roadside assistance is because of battery problems. There are various factors that can adversely affect even the most powerful and high-performance batteries, shortening their predicted lifespan or resulting in malfunctions when you’re least expecting them. Not only is breaking down stressful, it can also be dangerous if your battery suddenly stops working properly while you’re driving.

This is why it’s important to go to a trusted expert seller to buy a replacement car battery for your Mercedes.

Some of Mercedes’ models have two batteries. There’s a main starter battery in the boot with a secondary, smaller battery under the bonnet, near the windshield on the passenger side of the car. The charging system needed to support this set-up is highly sophisticated, as it has to balance the alternator's output across both batteries.
