How to Remove a Car Battery

Auto Mechanic Replacing Car Battery


Learning how to remove a car battery is fairly simple, although it is important to do the job the right way to ensure your safety. A car battery packs a hefty charge, so there are a number of precautions you should take before attempting to disconnect and remove it from your vehicle. The service team at Capital Ford Lincoln has prepared this step-by-step guide to properly removing a car battery. If you decide that you’d rather have a professional do the job for you, schedule a service appointment at our dealership in Regina.

Removing a Car Battery: Preparation

Before you attempt to remove a car battery, make sure that you follow these preliminary steps:

  • Park your car in a well-ventilated area.
  • Make sure your car is turned off. Attempting to remove the battery while the car is running is extremely dangerous.
  • To prevent electrical shock, remove any jewelry you may be wearing.
  • Wear insulated gloves and safety goggles for protection.
  • Have zip ties handy to keep battery cables separated from each other and from any metal-to-metal contact.

Removing a Car Battery: Removal

Once you have everything ready, follow these instructions on how to remove a car battery:

  1. Locate the negative battery terminal, and use a wrench or pliers to hold the bolt head of the terminal still.
  2. With another wrench or set of pliers, remove the nut, pull off the negative cable, and secure it away from the battery.
  3. Repeat steps 1 and 2 for the positive cable, being extra careful to ensure the two battery cables do not touch.
  4. Most batteries are held in place by a securing bracket. If this is the case for your battery, remove the securing bracket’s screws and bolts.
  5. Lift the battery straight up and out of the engine compartment. Be aware that a battery can weigh up to 40 pounds.

How Many Volts is a Car Battery?

A fully charged battery typically carries a charge of 12.6 volts or higher, although the voltage can range from 13.7 to 14.7 volts when the engine is running. While you can test your car battery voltage with a digital multimeter, which can be purchased at most Weyburn-area hardware or auto parts stores, there’s an easy way to test your battery without one. Just follow these steps:

  • Start your vehicle and turn on the headlights.
  • Check the brightness of the lights.
  • If the lights are dim, they may be running on your battery alone.
  • If the lights get brighter when you rev the engine, the alternator is likely not producing enough current when idle to keep the battery charged.
  • If there is no change in brightness when you rev the engine, your battery is functioning normally.
