How to replace a Mercedes battery

Model: Mercedes Mercedes Various
Part: Battery

In this video, learn how to replace the battery in a Mercedes: it is relatively easy, so you can do it yourself and save some money. Open the bonnet and lift the protective grille located on the left side of the engine bay. There are various sizes of OEM or AGM batteries, which can be positioned as H6, H7, H8, or H9, but this code is rarely found on the label. If you are unsure of which model it might be, the best approach is to measure its height and length: the key difference is the length, and many online resources recommend the H6 for the W205 version.
