How do you change the battery on a Peugeot 306?

To change the battery on a Peugeot 306, start by ensuring the vehicle is turned off and the keys are removed from the ignition. Open the hood and locate the battery; disconnect the negative terminal first (usually marked with a minus sign) followed by the positive terminal. Remove any securing brackets, lift out the old battery, and place the new one in its spot. Finally, reconnect the positive terminal first, then the negative, and ensure everything is secured before closing the hood.
