Battery replacement for B-Class W246


Captiva

Recommended Posts

Can someone provide guidance on how to remove the primary battery from the engine compartment? Insufficient space seems to hinder access to the terminals, and I cannot locate a hold-down clamp.

Based on the photographs. A metal bar seems to extend from the negative terminal of the battery, and I cannot locate a clamp bolt. The plastic encasing the battery seems to be divided into two halves, although I cannot discern how it separates.
The new battery weighs over 20 kg, making it difficult to manoeuvre in and out of the area (assuming I can ascertain how to remove the old one!). It may be necessary to enlist the services of the local garage if I can successfully jump-start the vehicle to drive it there.

The W246 has a distinct but more straightforward configuration.
Detach the bonnet release cable from the battery cover. Detach the clamp securing the wire loom to the battery cover and slide the cover forward to remove it. Remove the connections and the fastening clamp located along the side of the battery. Elevate the battery and extract it towards the front of the vehicle, preferably with assistance due to its weight. Revert the procedure using the new battery. The battery compartment may be disassembled for improved accessibility, secured by many clips.
