Let's see how to replace the battery of a Mercedes Class B W245: we find it in the driver's side door compartment, and it is accessible by removing the panel that covers it with a flat screwdriver. Once we have the battery in front of us, we disconnect the negative terminal (the black one) and then the positive terminal (the red one), loosen the two screws of the support and pull the handle to remove the old battery.

Clean the base from dust, rust and residue and insert the new battery, making sure to put it in the same way as it was before. Tighten the support, connect the positive pole, then the negative one and reassemble the battery cover.

The recommended battery is a 70 Ah FB that we can find on E-Bay, Varta brand with code 395673198032 at the price of 130.99 euros with free delivery in 2 days.
