Locate the Battery
They are typically attached by bolts under the hood of the vehicle. You need to get to it soon. Check the owner’s manual of your vehicle if this is the first time you’ve done so. It will instruct you on how to do it and indicate the location of the safety catch under the front hood. The batteries in some automobiles are hidden away in the trunk. If you are unable to locate your battery under the hood, it is almost certainly located in the vehicle’s rear. Again, make sure by checking the owner’s manual.
Locate the Positive and Negative Terminals
One of the most crucial steps is this one. The positive terminal is denoted by a “+,” while the negative terminal is denoted by a “-.” You will need to remove the plastic caps that cover the terminals of some batteries in order to access the battery cables—the wires that connect the battery to the rest of the vehicle—and the cable clamps that cover the terminals in order to disconnect the battery.

Find the Right Wrenches
Depending on how much room 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 will only need a few wrenches to complete the task. You’ll have to buy a set of wrenches or borrow them from a friend or family member. You will likely require a 10-millimeter open-end wrench to disconnect the cables because most but not all battery-cable clamps have bolts that are 10 millimeters long. Additionally, it will be useful to have a set of socket wrenches that includes that same-sized socket. In some situations, all you need is an adjustable open-end wrench.
Unbolt the Cables
You must exercise caution in this area. Verify that the vehicle’s ignition is off. When working around batteries, wearing eye protection is a good idea. In the first place, unbolt the negative battery link and separate it by lifting it free. To pull it off, it might require some wriggling and twisting. Be certain never to allow the wrench to contact both the negative and positive terminals simultaneously. Even though the battery is technically dead, there might still be enough electricity in it to short it out and start a fire. You don’t want any fires near the battery or in the engine compartment. The engine-control computer or electrical system of your vehicle may also be damage if the battery is shorted out in this manner. Push the negative cable far out of the way after you remove it. Now, take the positive cable out.

Remove the Battery Hold-Down Clamp
A clamp that secures a battery to the tray it sits on is use to secure many batteries. This clamp must be remove before you can lift it out of the car. Because the bolts that hold the battery can be low in the battery tray, this will probably require a socket wrench with an extension. Congratulations! Your battery is now free!
Conclusion
Be aware that if you disconnect the negative cable, a fully charged battery will retain its charge for six months to a year if you remove the battery cables to store your vehicle. Push the cable out of the way if you are disconnecting the negative cable but leaving the battery in place. Use zip ties to secure it in place in the event that it springs back into place and touches either battery terminal. Better yet, purchase a battery-disconnect switch that attaches to the negative terminal and performs the same function as removing the cables at any time.
