Buying Guide and FAQs

Car Battery – What Is It?

The car battery is the rechargeable source of energy for cars. It can power the electrical systems of a vehicle. It’s a wet-cell battery that features 6 cells that are linked in a series for producing 12V for smaller units and 24V for the bigger ones. 

The main function of a car battery is starting a vehicle, operating the lighting, powering the ignition. The cell is tiny and generates a low voltage. Yet, it can provide a surprising amount of power.

Aside from starting your engine and giving power to your headlamps, the car battery can also give the needed power to the electrical devices available in your car. These are the cameras, stereos, navigational equipment, OEM, and aftermarket accessories. 

What Features Should One Look for in the Best Car Battery?

No car battery is perfect. Each model offers a specific set of features that can suit specific needs and types of vehicles. Every motorist has his list of the specific requisites. To get the product that suits your needs, here are some essential factors that you should consider:


When looking for the best car battery, make sure you go for something that requires less maintenance. If it does not call for maintenance, then that would be better. 


A car battery is not what you can call “cheap”. Thus, buying a car battery that can offer the best in terms of longevity will be the one to help you save money. To make a good buying decision, you need to consider the climate and driving conditions your car can manage. 


It’s not only the engine of your car will get more power. Certain components, such as the sound systems, sap more juice. Therefore, you must ensure your battery can provide enough power for all those necessary components to ensure a smooth operation for a long period.

Value for the Money

While it can be doubtful to settle for a premium car battery, that does not mean you won’t benefit from it. Though you should depend more on the price as the cheapness of a car battery can be deceiving, you still need to ensure your preferred car battery can offer the best return on investment.


How does the car battery work?

It gives a blow of power, which will be sufficient for all the electrical components. This way, your car’s engine will start and provide a smoother driving experience. A car battery gives life to your car via a chemical reaction. In this process, your car battery converts the chemical energy to electrical energy to deliver voltage to your car’s starter. The car battery stabilizes the energy as well to keep your car’s engine running properly. 

Why does a car battery fail? 

It happens due to several reasons. It can be due to poor car maintenance and your bad habits as a driver like you leave the headlights on through the night. Extremely hot and cold temperatures can also be a culprit. The same is the case for the parasitic drains in your vehicle’s electrical system. 

Is adding water to the car battery helpful?

If the car battery is not maintenance-free (not sealed), then you must add some water every now and then to prevent it from getting dry. Distilled water must be used to fill the battery. Add it only after checking the water levels. Check the water levels for every 5 charges. 


Your car deserves a good battery – something that will make the startup easier. It has to last long and somehow able to withstand the harshness of the weather. Hopefully, you end up with a smarter buying decision with what you have learned from here. When in doubt, check again the guidelines above to have a regret-free purchase.
