An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle. Its primary function is to supply an electric current to the electric starter motor, which in turn ignites the internal combustion engine that powers the vehicle’s propulsion system. The battery continues to power the car’s electrical systems even after the engine has started, and as demand rises and falls, the alternator charges the battery.
Less than three percent of the battery’s capacity is typically used for starting. Because of this, automotive batteries are made to provide the highest current for a brief amount of time. For starting, lighting, and ignition purposes, they are sometimes referred to as “SLI batteries.” The lifespan of SLI batteries can be shortened by a full discharge because they are not intended for deep discharge. – source wikipedia
Every car owner must be able to disconnect the battery. Nevertheless, it’s not a really challenging task, so let us guide you through it. Switch Off Your Automobile’s Ignition First: Turn off your car before starting the procedure of disconnecting your battery. Never attempt to unplug the battery of your automobile while it is running. If you have them available, we also advise employing safety gear such as gloves and safety goggles.
Locate the negative wire of your automobile’s battery. With the engine off, lift the hood of your car by using the release mechanism inside the cabin or on the hood itself. Locate your automobile’s battery after it is started. Near the surface of the engine compartment, there are two big wires attached to these substantial, block-like components. A car battery may occasionally be found in the trunk.
If you’re having trouble finding it, check with the manufacturer to find out where your battery is exactly. When you’ve identified it, look at the negative connection of the battery. It is an electrical connection with a cable connected that is normally on top of the battery. A “-” symbol should be used to indicate the negative terminal, and a “+” sign should be used to indicate the positive terminal. The positive terminal will be red and have a red plastic cap, whereas the negative terminal will be black and perhaps have a black plastic label cover.

How to replace car battery?
Since car batteries are a very common technology, there is typically little chance of getting shocked by electricity. Low risk, however, does not imply no risk. Car batteries need to be handled with extreme caution. Think about the following advice before taking any action: If at all feasible, wear long sleeves and long pants. An energy-storing mild acid is present in your car battery. If it comes in contact with skin, it can result in severe to minor chemical burns. When lifting, make sure the battery is upright and try to keep it away from your skin. Always check your batteries, whether they are brand-new or used, for any cracks, bulges, or electrolyte leaks. These are all indications that the battery needs to be changed right away.
Don some rubber gloves. Even a thin rubber glove will serve as an insulator against electrical arcing and any unexpected acid spills. Although there are few hazards, keep in mind that there are still some risks. Wear protective eyewear. Where your battery is located, the engine bay is covered in a variety of fluids, dirt, and grime. Glasses will shield you from any potential acid spills as well as keep irritants out. When performing work within the engine, always wear glasses. When shifting a car battery, use your legs as a support. Some automobile batteries can be as heavy as 40 lbs. Lift with your legs, not your back, to avoid injury.
The required equipment & tools
Car batteries typically aren’t too difficult to remove and reinstall. Some manufacturers might position them in strange, difficult-to-reach locations that require additional tools, but that is uncommon. You will require a socket set and/or a wrench set. In most cars, the bolts holding the terminals to the battery are typically secured with 10mm nuts or bolts. An adjustable crescent wrench might help if you’re unsure of the size, but be careful not to round out those nuts. There is probably an old battery to remove if you’re installing a new battery.
- Ensure that the automobile is locked and in a secure area. Make sure the garage door is open if it is there. Assume the vehicle is in park (or first gear if it has a manual transmission), the parking brake should be applied, and the back wheels are chocked.
- Depending on the car, open the trunk or hood. On rare occasions, the battery could be put in an awkward spot. Check the owner’s manual for the position of the battery if it is not clear.
- The positive and negative battery terminals can be found. Don’t forget that positive is red and negative is black. The positive terminal typically has a small, easily-removable plastic cover with a plus sign on it. There may be, but not invariably, a negative sign close to the negative terminal.
- To get started, remove the negative battery terminal first. Take your ratchet or wrench, and turn it slowly the other way. The nut or bolt probably only needs to be loosened slightly in order to remove the terminals. Move the negative battery terminal so it is not touching anything and wiggle it off of the battery positive. Verify that the battery terminal is not overly stretched or bound.
- Follow the same procedure for the positive battery terminal, paying attention to where the terminals are placed.
- Although not all cars have one, if yours does, remove the battery bracket or brace.
- Most batteries often include some type of grip hold, but it could be damaged or absent totally. Lifting the battery from the car should be done carefully.
- This is a wonderful opportunity to think about cleaning your battery terminals as an additional step.
Detailed Instructions for Installing a Car Battery
It’s time to install the new battery after removing the old one and cleaning the terminals. Take your new battery and place it where it belongs. Make sure the battery is firmly in place and pay attention to which terminals go where. Reinstall the battery’s securing posts if necessary. The positive terminal should be reconnected and tightened before the negative terminal.
Once everything is secured, start the car to check that everything is operating. The cables should be tight and impossible to slide on the terminals. If everything is in order, it should start right up. After you close the hood and remove all of your tools from the engine compartment, you’re done!
About Installing Car Batteries
We wish to try to address any questions you may have. In addition to selecting frequently asked topics from popular search results, we have also chosen typical points of misunderstanding from our experience. Below are the answers to such queries. Which way you install your battery matters. Without a doubt, yes. Your battery and vehicle are made to channel the energy from the battery in a single direction. Negative to negative, positive to positive. Any reversal of this could seriously harm the battery or electrical system of the car. Take a picture of the old battery before removing it for easy reference.
- The owner’s manual for your car should provide information on the size and kind of your battery. If not, the old battery frequently has a tag on the front or top that specifies the size and type of the battery. If none of those methods work, the auto parts store employee should be able to identify the proper battery type.
- The majority of neighborhood governments, junkyards, and car parts retailers provide battery recycling programs. Whatever you do, make sure to get rid of it properly! If not disposed of appropriately, the components in automotive batteries can be exceedingly damaging to the environment. That joke about “letting’s dump our batteries in the ocean” is simply a crude meme. Don’t do that, please.
