Loosen and remove the Positive (+) terminal from the battery. Secure the lead out of the way of the battery.

Remove any screws or clamps which are holding the battery in place. Take care not to damage the battery when doing this as damaging the battery may lead to acid leaking from it.

Once the battery is released from its holding clamp, remove the battery from the car. Remember the battery may be heavy so take care when lifting it out not to drop it or hit it off anything.

Install the new battery in position. Ensure that the Positive (+) and Negative(-) terminals are located in the same was as the battery that has been removed. This has to be done so as to ensure the correct leads are connected to the correct terminals. Also the leads may not have sufficient slack in them to connect a terminal on the opposite side as before.

Secure the battery back into place using any clamps and screws which were used previously.

Remove any plastic covers off the terminals of the battery if present.

Connect the Positive (+) lead to the battery on the Positive (+) terminal. Push the clamp down on the terminal as far as possible.

Connect the Negative (-) lead to the battery on the Negative(-) terminal. Push the clamp down on the terminal as far as possible. Take care not to over tighten the clamp on to the battery terminal as doing so will damage the clamp and terminal. This could allow the battery clamp to disconnect and could cause fire.
