The car battery in your car is the ultimate source

Things you should need:

1- A new car battery

2- Adjustable wrench

3- Wire brush

4- Lithium grease

5- Baking soda paste

Steps to replace a car battery: Step 1: First off, disconnect all the electrical circuits associated with the car battery. When dealing with car batteries always protect your hands with some materials like protective hand gloves or something like that. In every car battery, you will see a greenish like stuff. This is a corrosive at the same time acidic substance which if comes in contact with our naked hand, can cause serious damage like burns etc.

Step 2: Now test the battery - and make sure that it charges and discharges without any problems. You may use a wire brush and baking soda paste for removing that greenish on the battery terminals. Again, don't forget to protect your hands while dealing with car batteries (especially while dealing with that corrosive substance on the terminals).

Step 3: You will have to replace the battery if you think the charge is depleted. First of all you should be removing the connection from the positive terminal and then only attempt doing that at the negative terminal. Clean Car Battery Terminals at that time.

Step 4: Hold down the battery towards its compartment or room and then remove the screws and bolts associated with it.

Step 5: Now seek help from someone and together, lift the battery from the compartment. After that, if you find something in the compartment, clean it using the wire brush and baking soda paste. Generally, corrosive matter is seen over that place and it can only be cleaned using baking soda paste.

Step 6 : Now, it's time to replace the connections. You should start with the positive battery terminals. After doing at both the ends, you should be spraying lithium grease over the connections.

Step 7: Now, it's time for checking how things went. If everything went fine, you will see the electrical system in your vehicle working good as it did in the past.
