1. Open the hood of your Renault Master. The hood release is usually located inside the vehicle, near the driver's seat.
2. Locate the battery. The battery is usually located in the engine bay, near the front of the vehicle. It is a black box with two terminals, one positive and one negative.
3. Identify the positive and negative terminals. The positive terminal is usually marked with a plus sign (+), while the negative terminal is marked with a minus sign (-).
4. Disconnect the negative terminal. Use a wrench to loosen the nut that holds the negative terminal cable to the battery. Be careful not to touch the positive terminal with the wrench, as this could create a spark.
5. Disconnect the positive terminal. Use a wrench to loosen the nut that holds the positive terminal cable to the battery.
6. Remove the battery. Once the terminals are disconnected, you can remove the battery from the vehicle. Be careful not to drop the battery, as it is heavy and could cause injury.
7. Replace the battery. If you are replacing the battery, make sure that the new battery is the same size and type as the old battery. Connect the positive terminal first, and then the negative terminal.
8. Close the hood of your Renault Master.
