How do you charge battery on Citroen Xsara Picasso?

To charge the battery on a Citroën Xsara Picasso, you can use a battery charger or jump leads. If using a battery charger, connect the charger clamps to the battery terminals—red to positive (+) and black to negative (-)—and follow the charger's instructions. For a jump start, connect the leads to the donor vehicle's battery and then to your Xsara Picasso's battery, ensuring the same positive and negative connections. Start the donor vehicle and let it run for a few minutes to charge your battery before attempting to start your car.
