In the current age of technological innovations, vehicles and their technologies are changing every day. New features are being added to automobiles to make them even more, smarter, efficient, and comfortable. To keep up with the new and increasing features of vehicle technology, auto batteries play an important role. To keep up with the increasing demand for vehicles, batteries and their technologies have gone through remarkable innovations.

Various types of batteries are now available in the market that serves different purposes for a different type of cars. The collection of choices and technologies being used is vast and it takes an expert to determine the correct type of battery for each car. 

Depending on the various features and purposes, the four main types of battery types that are currently being used in automotive vehicles are Standard Flooded Battery, Absorbent Glass Mat (AGM) Battery, Optima SpiralCell Technology, and Powerframe Grid Technology. 

These four main types of batteries are further divided into other categories depending on their chemical constructions and operations. To keep a healthy battery that works fine in all temperatures and conditions without damaging your vehicle or your traveling it is very important to maintain your battery. 

The most common problem that arises in batteries is them getting discharged or dead. For those who don’t possess complete knowledge about their battery types and the working of its mechanisms, it is very difficult to cope up with such problems. However, given below is a complete guide that will help you with the basics of your battery problems. 

Recharging a Car Battery with A Car Charger

Charging a car battery is a task that should be performed with high concentration because it is not as easy as charging a mobile phone and similarly not as safe. You have to be careful about not getting an electric shock to your body while keeping your body safe from the battery acid. You have to mark all of these hazards off the list while making sure to charge the battery completely to avoid any future issues with the battery. To recharge a car battery with a car charger, follow the below-given steps:

1.Check the Battery Health

The first step is to check for any possible problems that might have made the battery unfit for any further use. For example, look for corrosion effects on the battery terminals, sniff around for any smell odd smell as it may indicate a damaged battery that is giving off the chemical gas from its insides. 

2.Connect the Charger to the Battery 

After marking clear off all the pre-requisites, turn off the car and the car charger and then attach the red clip of the car charger to the positive terminal of the battery and the black clip to a stable point on the vehicle’s body. Attaching the black clip to the negative terminal of the body isn’t considered safe. 

3.Organize the Car Charger

Before starting the process it is very important to adjust the voltage and amperes of the car charger according to the requirements of your car battery. Starting with a lower value of current (amperes) is safe and reliable but it takes a lot of time. However, you can go with fast-charging by increasing the value of amperes. But make sure to check out the instruction manual. 

4.Turn on the Car Charger

In the next step, turn on your car charger depending on how it gets turned on. Some car chargers need an external power supply, whereas, some car chargers have their mechanisms and only need to be turned on themselves. After the charging starts the charger may or may not stop the charging process automatically depending on its type of operation. In any case, always make sure to keep an eye on the charger to avoid overcharging the battery. 

5.Remover the Car Charger

After the charger has stopped, automatically or manually check the charging indicator to show that the battery has been recharged completely. After making sure of the charging state, remove the charger’s power supply if it was plugged in. Now, remove the charging clips in the reverse order of their application. Remove the black clip from the car’s body first and then remove the red clip from the battery’s positive terminal.

Recharging a Car Battery by Driving 

There are several ways to recharge a car battery. However, which way should be implied when depends on the condition of the car battery. If the battery of your car has its charging voltage above 12 volts, it can be charged through the car’s alternator by driving around. Whereas, if the car battery’s voltage level is below 12 volts you would have to use a car charger for this purpose. 

If your car battery has a voltage level of 12 to 12.4 volts you can recharge the battery using its alternator through driving. In this method, to charge your car battery you have to drive the car around with minimum battery consumption possible. Turn of the car’s stereo system, the air conditioning, the lights (if its day time), and all other functions that may be costing the battery its potential. 

To keep the alternator in a state of providing maximum electricity to the battery for charging, make sure that you are driving your car at a higher RPM because higher revolutions of the alternator would allow it to send more power to the battery. Drive for around 30 minutes or more to ensure a charged battery that won’t die off again. 

Recharging a Car Battery After Leaving Lights On

One of the main reasons that car batteries die is that people leave their lights on and the engine off. When this happens, the engine is off and the alternator is also off, therefore, all of the battery’s potential is drained out through the headlight of your car. 

To recover from such a situation, the most common method is to jump-start your car. For that, all you need is a healthy battery of the same current and voltage specifications. After that, take the jumper cables and attach one end of the red jumper cable to the positive terminal of the dead battery and the other end to the positive terminal of the healthy battery. 

The arrangement for the negative terminal is different. Attach one end of the black jumper cable to the healthy battery’s negative terminal and the other end to a stable metallic surface of the car with the dead battery. Turn on the working vehicle and wait for a few minutes until the dead battery is recharged. After 15 minutes, turn on the battery and the car will start since the battery will now be recharged.
