Step 1: Locate the Negative Unit

Looking at the battery, you might find it confusing on which battery terminal to remove. First, take out the negative terminal. It usually has a black rubber indicator added to the negative sign (-) that is placed on the head or nearby.

Use the pair of pliers to hold the battery firmly to the platform and then loosen the screws with the wrench. Afterward, drag the negative wire off from the terminal and keep safely away from the battery.

Step 2: Locate the Positive Unit and Replicate Step One

Carry out the same process as with the negative terminal for the positive terminal. Also, safeguard the positive wire head with the zip straps when you remove it from the terminal.

It’s crucial to prevent the positive wire from touching the negative wire or any other part of the car engine. The reason is that the wire has a remnant charge that can hamper the electrical set up of the vehicle if you allow it to discharge.

Step 3: Detach the Protective Bracket

The protective bracket helps to grip the battery firmly to its platform. Without detaching this frame, you can’t move the cell from its position. So loosen the nuts of this frame with the flexible wrench and remove this frame altogether.

Step 4: Take Out the Battery

Once you’ve detached the protective frame, you can safely pull out the battery from its structure. Make sure your complete personal protective equipment (PPE) is on to avoid injuries.

Grab the battery by the handle and pull it from its position in the engine compartment. You should do this with care as car batteries are very weighty. Some can weigh up to 20kg, so handle with care.

In the case that the terminals are in a corner with little space, use a ratchet extender to twist and loosen the head.

Step 3: Loosen Out the Head Screws

Turn the screws with the socket and ratchet you fixed in an anticlockwise manner. It would be best if you do the same for both the negative and positive terminals.
