How To Change A Car Battery

Discover how to change a car battery in a safe and efficient way with VideoJug's easy-to-follow explanation to a car battery change Discover how to change a car battery in a safe and efficient way with VideoJug's easy-to-follow explanation to a car battery change

Step 1: Set up a secure working environment

Park on a flat and level surface at a safe distance from traffic and any inflammable materials.
Put on the parking brake .....
and put the gear stick into first gear. In automatic cars place the gear stick in the Parking Position.

Work in a well-ventilated area away from sparks or open flames. Do not smoke.

Use a memory keeper for your car's electronic devices.
Disconnecting the battery will erase PIN codes and settings for radios and navigation systems, unless you use a memory keeper.
Temporarily remove the cigarette lighter and plug the memory keeper into the lighter socket.
If you don't have this device make sure you have all the PIN numbers for your electronic equipment before you start. Use your car manual to see what devices may be affected.

Step 2: Open the bonnet

Release the bonnet with the lever inside the car.
Move the catch on the bonnet itself to open it.
Lift the bonnet and secure it with the prop rod.

Step 3: Locate the battery

Look for the battery under the bonnet in the engine block's layout. It is usually in an accessible part on either side of the car's frame. Look for a rectangular box with two attached two cables.

Step 4: Identify battery terminals

Next we are going to find the positive and the negative terminals of the old car battery. You will see a plus sign for positive and a minus sign for negative.
Usually the positive terminal socket is bigger and has a red cable running from it, whereas the smaller negative terminal socket has a black cable attached to it.

Step 5: Disconnect the negative terminal

Start disconnecting the battery with the negative terminal socket first.
This avoids creating a short circuit. As the negative terminal is connected to the chassis of the car you always disconnect this one first and reconnect it last.

Step 6: Disconnect the positive terminal

You should never connect the two battery terminals directly. Also, never leave any metal objects such as spanner, on the battery, as the two terminals might be connected, causing a short circuit.

Step 7: Remove the car battery

First unfasten the battery holder. Remove any screws, clamps or bars holding the battery in place. Remember how to refit everything for afterwards and store all the parts in a safe place.
Now carefully lift the battery up and out of the tray.

Old batteries can be taken to a recycling facility. Do not throw the battery into ordinary waste bin

Step 8: Replace battery

Take the new battery and carefully place it on the tray.
Fit on any parts that keep the battery firmly in its place.

Step 9: Reconnect the positive terminal

Once the battery is properly in place, check to make sure there is no corrosion on the battery cables. We clean them with the brush as required. Then we can finally reconnect the cables starting with the positive terminal. Tighten the clamps with the wrench.

Step 10: Reconnect the negative terminal

Slide the cable over the negative terminal and tighten the clamp with the wrench.

Step 11: Apply battery lithium grease

Cover the terminals with lithium grease as this prevents corrosion. Spray the grease on carefully, and avoid covering any other parts of the engine block.

Step 12: Close the bonnet

Finally, shut the bonnet firmly and start your car.

Check if all electronic devices work properly.

Restart all your electronic equipment by typing in the PIN code if necessary.
And that is how to replace your car battery the Videojug way!

    Well this is very basic and not necessarily true for all cars. Older vehicles, <1994 do not require a "memory keeper". And it's is not absolutely necessary on any car. But as the video states, the lack of a "memory keeper" type device will cause computer info to be lost once the battery is disconnected. HOWEVER, you can rebuild the engine computer info that was lost through some simple steps. Using "memory keepers" is a hit-and-miss technique as they doesn't always work perfectly, and you may still lose some or all computer info. But it's better safe than sorry!

    Auto batteries typically last only 2 to 3 years so it's no surprise that a flat battery is the most common reason why your car engine won't start. The trick is to recognise the tell tale signs of a failing battery and change it before it fails completely and leaves you stranded miles from home, late at night in the cold. Your Tool Box should also ready at any time.

    It should also be pointed out some vehicles have multiple batteries (my '95 Toyota Surf/4Runner for example). You need to disconnect them both, and you need to do both -ve terminals before the +ve terminals when disconnecting, and both +ve then -ve when reconnecting.

    Battery lithium grease? I use Vaseline and apply to the terminals before attaching the leads.
