How Much Does It Cost to Replace the Mercedes-Benz Electric Car Battery?

The cost to replace a Mercedes-Benz electric car battery can vary significantly depending on the model and year of the vehicle. As of my last knowledge update in August 2023, here are some estimates:

Estimates for Specific Models

Mercedes-Benz EQC: The battery replacement cost can range from $10,000 to $15,000. Mercedes-Benz EQS: Replacement costs might be higher, potentially between $15,000 and $25,000. Mercedes-Benz EQA: Costs could be around $10,000 to $15,000.

These prices typically include the cost of the battery itself as well as labor for installation. However, it is important to note that prices may vary based on location, dealership pricing, and any warranty coverage that may apply. Always check with a local dealership for the most accurate and up-to-date information.

Replacement Process and Cell Replacement

It is very expensive and relatively rare for a whole battery replacement to be necessary. Most cases are already fixed during the warranty period. Now that more cars are coming of age, it is still rare. In most cases, single cells that are bad can be replaced, often for a significantly lower cost. Depending on the brand and model, it can take anywhere from minutes to a full working day to replace the entire battery pack. For the newest structural batteries, it can be particularly challenging.

12V Accessory Battery Consideration

If you are referring to the 12V accessory battery, which is the closest analog to a gas car's starter battery, the answer is yes, with one important caveat. Because the accessory battery is charged and connected to the traction battery and the battery management system, there is an extra step to take to protect you and the car from damage. This involves performing a specific procedure, such as pulling out the rear seat of the car, to ensure the safety of the process.

Total Cost Analysis for Electric Cars

The cost to replace the battery in an electric car can vary depending on the specific electric vehicle (EV) model. Just as the cost of replacing the engine varies for different internal combustion engine (ICE) cars, the costs for battery replacement in EVs can range into the thousands of dollars, depending on your location. However, failures of traction batteries in EVs are often confined to a single cell, and replacing this cell is likely to be significantly cheaper, in the hundreds, rather than in the thousands.

Long-term wear also affects EV traction batteries, similar to how engine wear affects ICE engines, but the result is a loss of range rather than a loss of performance. One factor determining the resale value of a secondhand EV is the range. If a new EV has a range of 200 miles and the second-hand range is 195 miles, the resale price is unlikely to be affected significantly. However, if the range is reduced to 100 miles, the resale value may drop.

Especially for newer EV buyers, the impact of range reduction can be mitigated by the fact that someone might still want to buy a vehicle for their 40-mile commute but at a lower cost. In terms of labor, the time taken to change the battery is unlikely to be as long as the time to change the engine in an ICE vehicle.

Like any component, all cars depreciate, and both engine wear in ICEs and battery wear in EVs contribute to this depreciation.
