Remove the Terminal
Turn the negative terminal counterclockwise with a socket, drive the ratchet to loosen, and then pull it off the battery post. Once done, cover the terminal with a towel and place it far from the battery to avoid causing electrical contact accidentally.
Now turn over the positive terminal’s red plastic cover. And do the same thing with it as the previous terminal.
Replace the Old Battery
Now carefully remove your old battery from the engine bay and place it on the ground. Don’t drop or tip the battery over in the ground as it can leak the acid out and cause an accident. Clean the debris from the battery tray before placing the new one on it evenly.
Put your new battery into the plastic tray, keeping the positive post on the passenger side and the negative post on the driver’s side. Then lower the battery hold bar over the middle of the battery and make sure it doesn’t contact the terminals of the battery.
Secure the Battery
Attach the J hook bar to the back of the battery tray and secure the 10 mm bolt in its original place. Connect the positive terminal to the positive post, tighten the terminal nut snugly, and wrap it with a red plastic cover. But don’t over-tighten the nut, as it can crack or damage the battery post. Do the same thing on the negative side except covering. Finally, start the engine and flash the high beams to check the 12-volt battery replacement.
