When selecting a new battery, make sure it’s the correct type and size for your vehicle. Check your owner’s manual or consult with a mechanic if you’re unsure. Some common types of car batteries include:

  • Lead-acid batteries
  • AGM (Absorbed Glass Mat) batteries
  • Enhanced Flooded Batteries (EFB)
  • Start-Stop Batteries

Consider factors such as the battery’s cold cranking amps (CCA), reserve capacity (RC), and age before making a final decision.

Tools and Materials Needed

You’ll need the following tools and materials to install a car battery:

  • Battery terminals and cables
  • Battery hold-down clamp
  • Socket wrench or ratchet and socket
  • Wire brush
  • Terminal cleaner
  • Protective gloves and safety glasses

Precautions and Safety Measures

When working with batteries, it’s essential to take precautions to avoid injury or damage. Here are some key safety measures to follow:

  • Always disconnect the negative (black) cable first
  • Use protective gloves and safety glasses
  • Avoid touching electrical components with your bare hands
  • Keep the workspace well-ventilated
