The battery model for the Mercedes-Benz GLA200 is 12V1.2AH. Working Principle: The car battery, also known as the storage battery, is a type of battery. Its working principle involves converting chemical energy into electrical energy. Typically, cars use lead-acid batteries. The lifespan of the battery is closely related to the vehicle's driving conditions. Under normal driving conditions and without any electrical leakage, the battery can generally last for more than three years. Precautions: When the battery is low on charge, it should be promptly removed and recharged using a charger. In daily use, avoid parking the car in an open parking lot for extended periods. If the car is not used for a long time, it is necessary to warm up the engine periodically and ensure the battery is fully charged before use. Otherwise, it may cause damage to the battery.

I've been driving a Mercedes-Benz GLA200 for three years and have firsthand experience with battery model issues. Typically, it's a 12V 80Ah AGM battery, with original part numbers like A0009827508 being common, but it depends on the year and configuration. My 2019 model uses this number. The importance of the battery is obvious—nothing is more frustrating than not being able to start the car, especially in winter when low temperatures reduce cold cranking amps, leading to ignition failure. Once, I neglected maintenance, and the terminals corroded, causing the starter light to flash. I ended up paying a premium for a new battery. I recommend regularly checking battery health—don’t wait until it fails. Use a multimeter to monitor voltage, keeping it above 12.6V. When replacing the battery, it’s best to visit a specialized repair shop, as the Mercedes system requires a reset; otherwise, the start-stop function may fail. Battery lifespan is generally four to five years, but frequent short trips accelerate aging—using a battery charger can help extend its life. Always opt for OEM-compatible replacements, as counterfeit batteries may damage electronic components.

As a long-time car repair enthusiast, I often encounter GLA200 owners asking about battery models. It's usually an 80Ah AGM battery, specifically designed for Mercedes-Benz with part numbers like A0009827508, but the exact model should be verified against the vehicle's VIN. Replacing the battery is no trivial matter—I've seen cases where customers used regular lead-acid batteries and ended up frying the ECU. AGM batteries are designed to work with start-stop systems, and voltage fluctuations can trigger warning lights. The installation process is straightforward but requires caution: disconnect the negative terminal first, then remove the positive, using just a wrench for tools. The battery is located in a bracket on the left side under the hood, and size compatibility is crucial—wrong dimensions may prevent installation. During maintenance, check for terminal oxidation; cleaning with baking soda solution can prevent poor contact. Early signs of failure include slow starts or dim lights—don't ignore these. DIY replacement can save some money, with compatible models available online for around 100-200 RMB, but professional replacement is safer, especially since system reset is critical. In colder climates, batteries degrade faster, and protective covers can help.

I'm passionate about DIY battery replacement. The GLA200 model typically uses a 12V 80Ah AGM battery, with Mercedes-Benz universal part number A0009827508. When selecting, confirm the length, width, and height match the engine compartment. I've purchased several times at auto parts stores—prices are lower than OEM but performance is far worse. The process isn't complicated: prepare gloves and wrenches, disconnect power, remove the old battery, install the new one, test startup—just be careful not to reverse the wiring or you'll blow a fuse. After replacement, remember to reset the system using a diagnostic tool to clear codes and ensure proper functionality. Battery life is affected by driving habits—frequent short trips with insufficient charging can cause damage. Check voltage monthly; more full-charge driving can extend lifespan. Recommend choosing models with high cold cranking amps (CCA) for more reliable winter performance.
