STEP BY STEP
INSTRUCTIONS

by local expert Shajib Haque

Step 1

To change your car’s battery, open the bonnet and locate it - look in your handbook if unsure.

Step 2

Find the -ve (there’ll be a line across it with black wires) and +ve battery terminals (red wires). For the +ve terminal, undo the retaining nut (it’ll be in a clamp-like fitting). Pull the clamp away, making sure it doesn’t come into contact with the -ve terminal - there is a risk of electric shock.

Step 3

Use an old rag to cover the metal terminal to stop the terminal being exposed. Remove the -ve terminal by undoing the retaining nut.

Step 4

Loosen the securing bolt (typically found on the side of the battery) that holds it in place using the socket or spanner. Remove the battery securing clamp and carefully lift the battery out vertically. It will be heavy! Make sure the wing of your car is covered with an old blanket so no you don’t accidentally scratch the paint.

Step 5

Place the old battery on the floor and carefully put the new battery in. If you’ve got back problems, it might be an idea to ask someone else to do this.

Step 6

Re-attach the battery-securing clamp, tighten the securing bolt, remove the rags from the battery terminals and reattach them, connecting the positive one first. Check the terminals are tight, re-attach the covers and you’re good to go.

SAFETY INFORMATION

Do:

  • Take the battery to the tip to dispose of it safely
  • Cover your wing with a blanket to stop battery acid damaging your paint (unlikely but not worth the risk!)

Don't:

  • Let the two terminals come into contact with each other as it will cause a spark
