Failure to disconnect a battery correctly could result in bodily injury and property damage, so you must know which terminals need to be disconnected first.


Disconnecting your battery may seem daunting at first, but with just a few essential tools and some time invested, it’s actually relatively straightforward and can save both cost and performance for your car. By being self-reliant, you could avoid expensive mechanical repairs while keeping its performance and power at optimal levels.

Start by gathering all the tools necessary for disconnection of your battery, making sure the vehicle is off and working in an area with adequate lighting and ventilation. Furthermore, any metal jewelry worn can short out between positive and negative terminals of the battery and cause shorts between positive and negative terminals of said battery.

Locate and identify both positive and negative terminals on the battery. A wrench will be needed to loosen the nut that holds the cable to the negative terminal before doing the same with the positive terminal. For optimal results, disconnecting the negative first will reduce the risks of short-circuiting.

Once the cables have been disconnected, remove and place your battery on a flat surface away from your vehicle. It is essential to have a plan in place for its storage as its lifespan could decrease over time.

Safety precautions

No matter if you are performing repairs, resetting radio presets, or storing your car for some time – disconnecting its battery properly is always essential to protect both itself and the vehicle itself while also limiting exposure to hazardous compounds that could harm other people or yourself.

Protective gloves and goggles should always be worn when working with batteries, as the batteries can emit explosive gasses that could pose a significant danger. Make sure that you work in a well-ventilated area in order to minimize accidental exposure. Furthermore, consider using baking soda and water mixtures to clean battery terminals before beginning work on them.

Before beginning disconnection, ensure your vehicle is turned off and all electrical components have been disconnected. Your battery should typically be located under the hood; some OEMs place them in the trunk instead. Once found, begin by disconnecting its negative terminal by loosening and removing its nut with a wrench or socket; lift away from the terminal and insulate it with a nonconductive material.

Once the antagonistic terminal has been disconnected, disconnecting the positive one is simple and should follow. Just be wary not to touch either terminal, as this could cause an accidental short circuit that will destroy your battery. Once both terminals have been detached from one another, take action as required and store your battery somewhere safe.

Finding the battery

Car batteries power many features in your vehicle, from the clock and radio to electronic dashboard components. When disconnecting a battery for replacement purposes, these features may need to be reset; take the time to do this when disconnecting and disconnecting one to ensure everything goes smoothly.

As soon as your vehicle is off, open its hood and locate your battery. It should look large and block-like with two large cables attached; its negative terminal should usually be black with a minus sign nearby, while its positive terminal should be red. Use a wrench or unique terminal puller tool (available affordably at auto parts stores) to loosen its nut on the negative terminal, and unhook all cables from the battery by unthreading their nuts; finally, unplug and store the cable before disconnecting it entirely from the battery and placing cable to one side before taking further steps.

Once you have disconnected the negative terminal, it is advisable to wrap or cover it with plastic in order to avoid accidentally connecting it with metal components in your engine. Disconnecting the positive terminal may be more accessible, although extra care must be taken as batteries contain hydrogen gas, which could leak. Once both terminals have been detached from their respective battery trays, remove your battery.
Removing the battery

Disconnecting a car battery is typically an effortless endeavor that only requires essential tools and some time for completion.

As soon as you’re in, disconnect the negative battery cable – usually marked with a “-,” typically black and bearing a minus sign (-). Removing this terminal first helps avoid accidentally creating an electrical circuit by accidentally connecting your ratchet or wrench to it and creating an electrical current.

Once the antagonistic terminal has been unplugged, move on to the positive. Loosen the nut or bolt that holds the cable in place and pull away. Positive terminals typically feature red cables with plus signs (+), typically marked by loosening their secure nut or bolt and tightening. If there is also a battery hold-down wedge, this must also be removed before proceeding further.

Once the battery has been taken out, make sure it is cleaned before placing it on a flat surface free from potential hazards. Allowing any electronic systems time to adjust can also be helpful for proper storage; many auto shops provide this service free of charge when installing new batteries in vehicles brought into them.
