Where is the battery located in the Mercedes-Benz GLK260?

The battery of the Mercedes-Benz GLK260 is installed under the hood, in front of the front passenger seat. Here are some methods to extend the battery's lifespan: 1. Use the battery frequently: Most cars use lead-acid batteries. If the car is not used for a long time, the sulfuric acid inside will settle, leading to natural discharge. Prolonged inactivity can result in insufficient power supply and significantly reduce the battery's lifespan. 2. Clean the battery terminals: The area around the terminals is not completely sealed. When the car is running, any movement can cause the electrolyte to leak out of the terminals. This electrolyte can undergo chemical reactions in the air, affecting the battery's normal operation.
