What is the battery model for the Mercedes-Benz E200?

Mercedes-Benz E200 uses a 20-80 model battery. Here are the specific details: 1. Introduction: A battery is a type of storage cell, also known as an accumulator, which works by converting chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. 2. Working Principle: The negative electrode is a lead plate filled with sponge-like lead, and the positive electrode is a lead plate filled with lead dioxide, using 22-28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When discharging, metallic lead acts as the negative electrode, undergoing oxidation to form lead sulfate, while lead dioxide acts as the positive electrode, undergoing reduction to also form lead sulfate. When charging with direct current, lead and lead dioxide are generated at the respective electrodes. After disconnecting the power source, it returns to its pre-discharge state, forming a chemical cell. Lead-acid batteries can be repeatedly charged and discharged, known as secondary cells. Their voltage is 2V, and typically three lead-acid batteries are connected in series to achieve 6V. Automobiles use six lead-acid batteries connected in series to form a 12V battery pack. Regular lead-acid batteries require the addition of distilled water after some use to maintain the electrolyte's 22-28% dilute sulfuric acid concentration.

I once drove a Mercedes-Benz E200 and found that the battery model mainly depends on the vehicle's year and configuration. Commonly, it's a 12V AGM battery, such as VARTA AGM 80Ah or EFB versions, but the specifics should be checked against the label in the owner's manual or the VIN code. My car is a 2020 model, and I replaced it with the factory-recommended 80Ah, which cost around 1,000 yuan and worked well, providing stable starts. I recommend not attempting DIY replacements casually because Mercedes' electronic systems are sensitive, and using the wrong model might trigger a fault light. It's better to visit a 4S shop or an experienced repair shop to check the actual needs and also inspect the charging status to avoid breakdowns on the road. For daily maintenance, I check the battery terminals for oxidation every month and preheat the engine before starting in winter, which can extend the battery's lifespan by two to three years.

From a technical perspective, the Mercedes-Benz E200 commonly uses a 12V AGM battery, with models resembling VARTA or Bosch S6 series, featuring capacities between 70Ah and 80Ah to meet the high demands of start-stop systems. The AGM design offers vibration and heat resistance, reducing the risk of electrolyte leakage, though it is more expensive than standard lead-acid batteries. When selecting, ensure the CCA (Cold Cranking Amps) value meets the factory standards. After installation, reset the system settings to prevent false error reports from the computer. Avoid letting the battery charge drop below 50% for extended periods, turn off all power-consuming devices after parking, and perform quarterly maintenance with a smart charger. This routine helps prevent unexpected replacements and ensures safe driving.

The battery model for the Mercedes-Benz E200 is typically a 12V AGM, with a capacity of 70Ah or 80Ah, such as the common VARTA 80Ah AGM. After purchasing the car, I usually check the replacement guide at the end of the owner's manual or the label under the hood to directly verify the year and version. If there's a mismatch, I buy the original part from a reliable brand instead of opting for cheaper aftermarket parts that are prone to failure. When installing it yourself, remember to wear insulated gloves for safety and avoid short-circuiting the positive and negative terminals; if the lights flicker or are unstable, it might be time for a replacement. Regularly test the voltage to keep it above 12.6V, and after replacement, drive a few kilometers to allow the system to adapt.
