Automotive maintenance is primarily based upon the art of taking things apart and putting them back together. Sometimes that involves nuts and bolts, sometimes it involves gaskets, and other times it involves wires and cables. In the case of a car battery, it is connected to the charging system with two heavy-duty cables attached to two top-mounted posts known as terminals.

To remove a battery, you must remove the cables from the terminals. Those terminals are labeled with a plus symbol and red indicators on the positive terminal and a minus symbol with black indicators. Crossing wires or removing the wrong cable first could lead to sparking or other harmful dangers, such as ripping a hole in the spacetime continuum, so you need to know what youre doing before you start taking things off.

To prevent dangerous situations, you need to understand how to properly handle a car battery, which is hot with voltage and traditionally filled with free-flowing acidyikes. The Drive has put together a step-by-step guide for how to disconnect a car battery. Follow along below.

Cleaning And Inspecting The Battery And Connections

  • 1Put on eye protection and gloves. Protecting your eyes is especially important when reinstalling your battery. If you accidentally mix up the positive and negative cables, for instance, the battery could overheat and burst, spraying the water or chemicals stored in the battery.XResearch source
  • Latex gloves will protect your hands if your battery leaks or bursts, but mechanic gloves will also offer protection from scratches and pinches.
  • Goggles offer the most protection, but traditional safety glasses are also fine.
  • 2Ensure the keys have been removed from the ignition. It’s important that none of the vehicle’s electronics are set to on when you reconnect the power from the battery, otherwise, the power surge could cause damage. If the keys are in the vehicle, turn the ignition to off and remove them for safety.XResearch source
  • Just having the key inserted in the ignition will turn on the door chime in many vehicles.
  • 3Clean the battery terminal posts with baking soda and water. Use a wire brush to remove any corrosion or buildup on the battery terminals before you put it back in the car. Add 1 tablespoon of baking soda to 2 cups of water to create a cleaning solution to help you remove stuck on corrosion.XResearch source
  • The baking soda and water mixture is abrasive enough to scrape away rust or old oil.
  • If you don’t have baking soda, you can use 100-grit sandpaper to get the same result.
  • Use a damp rag to remove the baking soda mixture when you’re done.

    Is The Battery Location Different For Different Vehicles

    While its easy to locate the battery in some vehicles, its a little more complicated for others. The battery may be directly under the hood or concealed under a cover. For other vehicles, it may be located towards the back of the car, usually sealed behind the trunk. Others might store the battery under the car floor or below the rear seat.

    To locate the car battery, you can either consult the car manual, or if youve lost it, you can check different areas of the car. You can also check online with the car brand and model to find out where the battery is located.

    Why Would I Need To Disconnect The Car Battery

    There are many reasons for disconnecting the car battery from the engine bay.

    Here are some of the usual ones:

    A. Replacing A Faulty Battery

    Putting in a new battery is one of the most common reasons for disconnecting the battery.

    Make sure the old battery is disposed of properly.

    B. Recharging A Flat Battery

    You may want to use a battery charger to recharge a flat car battery.

    Sometimes you dont have to remove the battery from the engine bay, but only disconnect the cables and hook the battery to the charger.

    If youre uncertain about using a battery charger, get a mechanic to handle the task for you. Youll also have the benefit of asking them to test it for you to find out why theres a battery drain in the first place.

    C. Cleaning Battery Corrosion

    Corroded battery terminals should be cleaned, as corrosion affects battery performance and can shorten its life.

    Its often a good idea to take out the battery from the engine compartment when cleaning to prevent corrosive elements and cleaning agents from falling on engine parts.

    D. Performing Car Maintenance

    Some engine maintenance may require the battery to be disconnected or taken out of the way to access engine parts.

    E. Storing A Car For An Extended Period

    If you plan on storing a vehicle for an extended period, its advisable to disconnect at least the negative terminal from your car battery. This prevents unnecessary battery drain, as a fully charged battery can hold its charge for 6-12 months if you do this.

    Connecting The Battery Terminals

  • 1Slide the positive battery cable onto the positive terminal. The positive cable will come from the alternator. Press the connector onto the terminal with your hand until it lies flat against the battery.XResearch source
  • If that connector won’t slip over the terminal post, use a wrench or socket and ratchet to loosen the bolt on the connector, then try again.
  • 2Use a wrench to tighten the cable onto the post. Once the positive cable is on the terminal, it needs to be tightened to ensure it can’t vibrate off while you’re driving. Use a wrench or socket to turn the bolt on the connector clockwise until it’s snug.XResearch source
  • On many batteries, it’s easier to use an open-ended wrench than a socket, but either will work.
  • Wiggle the wire on the terminal a bit with your hand to make sure it’s secure. If it moves at all, tighten the connector further.
  • 3Connect the negative cable to the negative post and tighten it as well. The negative cable should be installed just like the positive one was. Press it onto the terminal post with your hand, then tighten it with a wrench.XResearch source
  • If either cable can’t reach the appropriate terminal, it means the battery wasn’t oriented properly when you lowered it in.
  • Wiggle the connection on the negative terminal with your hand and tighten it some more if there’s any movement.
  • If it still doesn’t start, the battery itself may be dead. If so, try jump starting it.

    Find The Right Wrenches

    You will need at most only a couple of wrenches to get the job done, depending on how much space there is to maneuver the wrench and whether the battery cable uses a single bolt on the clamp or one that also uses a nut on the other end. You’ll have to borrow the wrenches from a friend or relative or buy a set. Most but not all battery-cable clamps have 10-millimeter bolts, so you’ll likely need a 10-millimeter open-end wrench to disconnect the cables. A socket-wrench set that includes that same-size socket will be helpful as well. In some cases, you can get by with just an adjustable open-end wrench.
