When your car battery goes flat, this can be very bad news for you. In such a case, it is necessary to replace it safely. When a car battery dies out completely, it normally refuses to recharge. If this happens to you on the road, you have no choice but to wait for Roadside Assistance to arrive. Usually, car batteries last for between one and four years. This lifespan can increase or decrease based on your driving patterns. Car batteries are heavy, corrosive and possibly flammable. As such, many drivers enlist professional mechanics to fix their dead car batteries. However, you can actually decide to do it yourself. Here is how to do it.
The things that you will need:
- An adjustable wrench
- Some disposable rubber gloves
- Lint-free rags that are clean
- Some baking soda and water
- A battery brush
- Safety goggles
- Post-cleaning tool
Begin by turning the car off and putting it on the park. Once you have done so, set the parking brake. Proceed to place a towel on your fender. This protects the paint from any acid which could spill upon it. As you remove the faulty battery, make sure to refer to your car’s manual.
Remove the battery from its terminals
If your vehicle has negative ground, make the nut and bolt which hold the battery cable clamp looser. Make sure it points to the negative terminal. In case your vehicle has a positive ground, make sure to loosen the positive cable first.
Extract the fasteners
If there are any screws or fastening devices that are keeping the battery in place, remove them. Make sure that you remember where you put them so that they don’t roll under your vehicle. Lift the battery out of your car. Wear your gloves when performing this task.
Perform an inspection
Take a long, careful look at the tray upon which the old car battery was placed upon. If there are some corrosive deposits or it is rusty, put some baking soda in water. After that, clean the tray with this solution. Ensure that your hands are well protected using gloves. Take some time to clean up the battery terminals too.
Place the new battery
Pick up the new battery and place it on the tray. Ensure that it is facing a direction which is similar to that of the previous battery. Furthermore, make sure that it is firmly seated.
Place the fasteners
Pick up the screws or fasteners and put them back in place. Make sure that they are firmly installed. The battery should not have any wiggle.
Reconnect the cables
Pick up the battery cables and reconnect them. Make sure to do so in a reverse order to which you took them off. For example, if your car is negatively grounded, connect the positive cable first. Ascertain that the clamps which you have reconnected are all holding the battery posts firmly.
Get rid of the old battery in an Eco-Friendly way
Car batteries are toxic. This means that they should be disposed of in a legal and responsible way. There are special recycling locations that can accept car batteries and charge only a small amount to get rid of them for you. Do not put the old car battery in a recycling bin or rubbish can.
Important points to note
Auto association memberships or roadside assistance programs normally include battery replacement in their packages. This means that they replace your battery whenever required for you.
You could ruin your car’s electrical system if you perform the battery replacement incorrectly. You could also void your vehicle warranty.
It is not advisable to conclude that any negative operation by your vehicle is due to a bad battery. Other possible issues include a malfunctioning starter motor or a faulty alternator. In case you suspect these issues, ensure that a professional diagnostic test is performed on your vehicle.
When professionals are changing your car’s battery, they make sure that there is a second source of power available. This makes sure that you don’t lose the settings or security codes which are needed in your car’s onboard computer.
