First, it’s important to know what type of battery is in your car. The two most popular battery types are lead-acid and lithium-ion. Lead batteries have been in use for decades and are the most popular, although lithium-ion batteries are becoming more common in new vehicles. Each type of battery has its own set of instructions for changing, so be sure to consult your owner’s manual or the manufacturer’s website for specific instructions.

Required tools and materials

  1. New car battery
  2. Ratchet and socket set
  3. Battery terminals (if necessary)
  4. Wrench (if necessary)
  5. Protective gloves

Your safety comes first

Never work on a car battery without taking proper safety precautions. Batteries release hydrogen gas, which is explosive. Always work in a well-aired area and wear protective gloves when doing battery work.

Find your battery

The first step is to find your battery. It is usually located near the engine and close to the firewall. Once you’ve located it, make a note of the positive and negative terminals. A positive terminal will almost always be marked with a “+” sign, while a negative terminal will nearly always be labelled with a “-” sign.
