Do you want to replace the secondary battery on a Mercedes E-Class? Remove the battery from the trunk or from the vehicle's floor. Open the car door or hatch and locate the small auxiliary battery stored inside the plastic container.

Once you remove the cover from the dedicated compartment, you will find the auxiliary battery with the electrical terminals. Unscrew the fastening pins of the battery terminals, then remove the battery from the compartment and replace it with a new one (same voltage).

Connect the electrical terminals to the new battery and test its operation.

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins.
