How To: Install a Battery in Your Vehicle

So, before you get into the solution to the issue of whether or not can you start a car without battery, lets have a look at the electrical system to better clarify this question.

The battery, alternator, and other electronic parts make up the electrical system of your vehicle. Normally, the battery is utilized to power anything that requires electricity.

Furthermore, the charging system utilizes more mechanical engine power to refill the battery.

Whereas the car is in motion, this cycle continues, and when you switch it off, you must have a rechargeable battery pack that is ready to start your car again.

Step : Find The Car Battery

Although it might sound silly, not all car batteries are located under the bonnet in the engine bay. Consult the owner’s manual to confirm where the battery is placed – it could be in the boot or under one of the rear seats to save space or enhance weight distribution. It might also have a plastic cover to protect it which needs to be removed.

Disconnect Negative And Positive Battery Cables

Start with the negative terminal and disconnect the negative battery cable. Look for a black cable and a minus symbol. You may need to use a ratchet to loosen and remove the clamp. Once the clamp is off, move it safely out of the way.

Disconnect the positive terminal after the negative terminal. Positive terminal has a plus sign and the cable connected to it is usually red.

Although an automobile battery is normally charged by the cars alternator while the car is running, there are times when the battery dies for various reasons and needs to be connected to a charger.

    • Car won’t start after being jump started
    • Build-up of powdery residue on the battery terminals
    • Battery warning light on the dashboard
    • Check Engine warning light on the dashboard

    If your car fails to start without any warning lights appearing on the dashboard, it’s likely that you have a flat or dead battery. Before immediately buying a replacement battery and getting ready to change it, try and jump start the car.

    Once you’ve got the car running, take it for a drive with minimal electrical systems in use to try and recharge the battery and then turn it off. Return to the car in a couple of hours or the next day. If it starts without any issues, the battery was simply drained of power however, if the car doesn’t start again, the battery is unable to retain a charge and needs to be replaced.

    A battery needs a clear electrical current to work properly. If the battery terminals have a build-up of a whitish or blue residue around them, their performance will be affected.

    Find The Right Wrenches

    How to Install a Battery on Car

    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.
