Even a well-maintained car battery will become depleted over time and eventually lead to hard starting. Many automotive chains that sell car batteries will give a customer credit for an old battery because the core is recyclable. This type of battery is filled with corrosive acid that is potentially explosive and can cause serious injury, easily burning through clothes and skin. A car battery weighs 32 pounds (14.5 kg) or more and should be lifted out of the automobile with extreme care. When purchasing a new car battery, confirm that the negative and positive terminal posts are on the same side of the battery as your old one.
It’s a good idea to drive the car for 30 minutes or more once the new battery is installed.
I have a dead car battery right now but I have never changed one before and have no idea what I am doing.
There are a lot of auto parts stores that will change your battery for free or for a small charge if you buy the replacement battery from them.
You’ll first want to ensure the vehicle is off, in park, and remove the keys from the ignition. Car batteries are typically very heavy, between 40-60 pounds, so keep this in mind when lifting the battery out. At this point you’ll want to clean off any residue or corrosion in the battery trap, from the hold-down strap, and the terminals of the cables. Once everything is clean and completely dry, place the new battery in the vehicle’s battery tray.
Optionally (but recommended) you may spray each of the new terminals with a small amount of anti corrosion solution in order to get the most out of your new battery and to prevent having to clean off corrosion early on.
Carefully re-attach the cables to the terminals, taking care to place the red cable on the red terminal and the black cable on the black terminal. Once you’re confident everything is done, secured, and in place snugly, do a quick once-over. We hope this guide properly explained how to change a car battery so you can save some money by doing it yourself instead of paying for someone at a garage to change your car battery.

A battery check today can keep the tow truck away, says the Car Care Council, as it advises vehicle owners to have their battery tested and replaced if necessary this fall to avoid being stranded this winter.
Sooner or later all batteries have to be replaced, and excessive heat and overcharging are the two main reasons for shortened battery life. Be sure the electrical system is charging at the correct rate; overcharging can damage a battery as quickly as undercharging.
If your battery is the type that needs to be topped off, check it regularly, especially in hot weather.
Always replace a battery with one that’s rated at least as high as the one originally specified. A car battery is vital in supplying constant electricity flow into all electrical components in an automobile. In the market today, there are two types of batteries on sale, namely wet cell and the dry cell. Before proceeding to pop the hood, ensure that you have all the necessary tools to perform the job not forgetting correct battery size for your car type. Ensure that there is no gas source, open spark or flame near you before proceeding to dismantle the car battery negative terminal first. This simple DIY (do it yourself) tip on how to change car battery saves you tones of hassle at the workshop plus it is light on your wallet too.
A freshly manufactured lead-acid car battery is 100% charged, but sitting on the retail shelf for months it gradually self-discharges.
Bring a wrench or a combination of sockets and a ratchet for bolts that fasten cables to battery terminals and hold the battery clamp. Turn off the ignition switch, all electrical switches and breakers and electronic and electrical accessories and appliances in the car. Disconnect the grounded negative (-) black cable first from the old battery in your car because this will minimize the possibility of shorting the battery when you remove the other cables.
Thoroughly wash and clean the old battery and tray (case or box) with warm water and brush to minimize problems from acid or corrosion. Clean the cable terminals with a wire brush and baking soda and water if they're corroded or dirty. Connect the positive (+) red cable to the positive (+) terminal, tighten the hold-down bracket. Connect the negative (-) black cable to the negative (-) terminal and tighten its hold-down bracket as well.
When disconnecting the car battery you will lose the radio station presets, emissions computer settings, or radio security codes (some vehicle manufacturers - as an anti-theft measure - disable the radio if the power is cut until a special security code is entered).


Car batteries contain lead, acid, and plastic, and are dangerous to both you and the environment if disposed of incorrectly. To save wear on your starter and to keep your vehicle in tip-top shape, changing the battery will be required every three to five years under normal circumstances.
Moreover, it is illegal to throw a car battery in the trash in most places, making it convenient to trade in the old battery when you get a new one.
If there is corrosion present — it often looks like a white powder — neutralize it with a mixture of baking soda and water using an old toothbrush.
Remove the positive plastic cap if its present, and smear some petroleum jelly on the terminal post to help prevent corrosion.
I have changed a few batteries in my life and know what I am doing, but if I can get someone else to do the work why not? The process is virtually identical for all makes and models of vehicles unless you have a specialty hybrid or electric vehicle, at which point you would need to refer to your dealership. Place the strap you previously removed back over the new battery as it was before and secure the clamp via the method you previously used to remove it, making sure it’s securely in position and doesn’t move around at all. You may need a wrench in order to loosen the bolt enough to wiggle the cable free from the terminal. Secure your new battery in place with the hold-down strap you previous removed and ensure it’s tight and snug as you don’t want the battery moving around or shifting while you drive.
Try and move the battery back and forth in place to ensure the hold-down strap is on and secure. Visit Car Cosmetic’s blog to find more helpful tips and guides to keeping your vehicle in tip-top shape! Heat causes battery fluid to evaporate, thus damaging the internal structure of the battery. A loose battery can be knocked around while driving, causing the life of the battery to be shortened dramatically.
The wet cell requires top up of sulfuric acid in order for it to perform normally and has a lifespan of three to five years, whereas the dry cell type is maintenance free. Put it in a small plastic bag or cloth around it so that it will not touch the metal frame or engine components. To prevent this from happening you can temporarily connect a second 12-volt battery in parallel to the electrical system before changing a car battery. Do not put automotive batteries left after car battery replacement with other household recyclables in curbside bins. If your automotive retailer does not recycle old batteries, see if there are regional or national organizations, like the Automobile Association of America (AAA), that can do so. Many newer batteries are made with a handy strap handle, and straps are also available at automotive shops.
It will charge faster if drains, such as air conditioning, stereos, and unnecessary lights, are kept at a minimum.
If the vehicle sits unused for long periods of time, purchasing a device like a Battery Minder™ or Battery Tender™ is a good idea. I installed a new one, looks like everything is attached properly, but the car won't do anything when I try to turn the ignition over?
In order to change your car battery, you’ll want to first make sure the vehicle is off with the keys removed from the ignition. Once that’s loose, you should be able to lift the battery out of the tray it sits in by lifting it up and out. Most new batteries come with plastic caps over the terminals; one on the red and one on the black. Once tightened, wiggle it back and forth to check that it’s tight enough and won’t come loose during road vibrations. Prop the bonnet up using the rod in order to lock it in place while you work under the hood.
Otherwise, lift from the bottom and place the battery safely outside of your engine compartment.
You may use battery cleaning solution (also found at your local garage) or a simple mixture of water and baking soda.
Do each cable in one-step; only moving on to the black cable after the red cable is completely on and tightened down properly. If you have any issues starting your car, go back and double check the terminals and cables are connected and tight.
A malfunctioning component in the charging system, usually the voltage regulator, allows too high of a charging rate, leading to slow death for a battery.
Further, as corrosion accumulates on battery terminals it becomes an insulator, inhibiting current flow. Dismantle the battery holder which usually sits on top to enable you to lift the battery out from the engine bay.
Read the following guide on how to change a car battery, what equipment you need and how to recycle the old battery.


If you don't have a charger or time, just installing the battery and driving away is also acceptable. The temporary battery can be connected either over the battery cable leads or to the cigarette lighter plug if it is active when the ignition key is off (you can test this by pushing in the lighter).
When you buy a new car battery many shops will even pay you in exchange for your dead car battery. Alternately, you can lift the battery straight up and out by holding it at opposite corners. Open the bonnet and prop it up as we’ve covered in a previous guide on how to open your car bonnet. You don’t want to remove the nut entirely, instead, loosen it enough to where you can wiggle the wire off the terminal.
Locate your battery; in most cases it will be on the right-hand side of your engine compartment. A few gentle taps to the side of the cable after loosening the bolt should be enough to remove the cable.
If there is heavy corrosion crusted on the cable connectors, you may need to use a wire brush or look into a battery cleaner at the shop.
Colder temperatures increase the thickness of the engine oil, making the engine harder to turn over and the battery work harder, leading to harder starting.
If there are encrusted deposits on the battery, carefully clean the terminals with a wire brush dipped in baking soda and water. If you do need to disconnect the battery, remove the negative terminal first, then the positive. An alternator is then used to restore lost charges in a battery when the engine is operational. You can buy such a car memory keeper that plugs into your 12V cigarette lighter (with or without a 9V battery) at electronics and auto stores for $10. Do not lay tools across the top of the battery because a conductive metal might touch both terminals simultaneously causing a short, sparks, or a potential explosion.
Locate your battery; it’s a large rectangular object with a red and black terminal with some heavy duty cables clamped to either side. If there is significant resistance and the bolt is sufficiently loose, wiggle the wire up and down to free it up. Next, you’ll ideally want to lightly spray each individual terminal with a coat of anti-corrosion solution. While you’re done at this point, it’s a good idea to go back over each step to make sure everything is snug and secure while maintaining a good connection to the terminals. It will be large and rectangular with two thick cables coming from the battery terminals which are colour coded Red and Black.
In some cases, major corrosion can make it very difficult to remove the cable in which case a Battery Terminal Puller is recommended and is sold at most garages.
Ensure that the correct terminal is in place before proceeding to install the battery holder and tighten all nuts and bolts.
The car should be able to come to life in one crank assuming all other engine parts are in good condition.
Using either battery cleaner or a mixture of baking soda and water, clean off any corrosion residue left over in the tray where the old battery was. While this is an optional step, it helps your battery to last longer by avoiding corrosion buildup you’ll find on most old batteries and prolong the best connection.
If the battery cables move around, you may not have a good connection and it may not start due to a weak connection. The electrolyte, especially sulfuric acid, can be neutralized, repurposed, or converted into sodium sulfate used in fertilizers or dyes. If you can’t find it there try looking in the boot, on some models the manufacture decided to placed it there to safe space in the front.
The cable should come off easily unless you have corrosion damage, at which point you’ll want to look into a battery terminal puller; however in most cases that’s unnecessary. Using a wire brush, clean off the battery connectors to free up any rust or corrosion to ensure a good connection to the new replacement. Repeat this process for the red terminal and set each cable to their respective sides of the battery allowing room to perform the next step. Many local recycling depots, battery recycling companies, landfills, and transfer stations will accept car batteries free of charge for disposal.
