Are you looking for a car battery and you do not know which one to choose? Do you want to know which the best car batteries are? Do you need tips for buying a portable battery for your car? Then you got this. The Battery Man Guide is here to help you choose the best battery for your car. Below I will present the criteria according to which you should make this choice.
How do you choose the best car batteries?
When choosing a car battery, do not look only at a price, but take into account what is compatible with the characteristics of your car (cylinder capacity, accessories, fuel type), and if it is a quality battery to use for as long as possible.
I insist on the quality of the car battery, mainly because it is the vital component for the proper functioning of the electrical system and is not a component that you change every year, but after many years (depending on its quality).
The size of the most suitable one
Size refers to the height, length, and width of the battery. Car batteries come in different sizes so that they fit perfectly into the unique place of each car. The required size varies from one machine to another, so before purchasing, read the technical specifications of your vehicle, where you can find size and amperage information. You can also consult the car battery maker’s guide so that you can see the right size for your car.
Purchasing an inappropriate car battery can be described as a waste of money, my recommendation is to return it as soon as possible.
The capacity of the best car battery
The function of the car battery refers to its possibilities to store a certain amount of electric power, and the choice is made depending on the car’s alternator. Capacity to measure in Ah (ampere per hour). Thus, a 70 Ah battery will be discharged by a 10 Ah consumer in 7 hours.
I advise you to make a choice based on the information contained in the vehicle’s technical book, and never choose a car battery with a lower capacity than the one specified in the technical manual because you risk that the car will not work in normal conditions.
Instead, if you want something stronger, you can make such a choice. According to the experts in the matter, a battery with a capacity higher than 30% compared to the recommendations of the car manufacturer does not affect the functioning of the vehicle. Read more here.
The capacity of the car battery will decrease over time, depending on the degree of demand and the quality of the cell. I advise you to choose a car battery from well-known brands. Keep in mind that the battery is automatically charged to the car’s rectifier, and if there is repeated start-up, short and frequent travel, there is a risk of battery discharge.
The cold start
This parameter measures the battery’s ability to start the car even in freezing weather. If the vehicle is parked for a longer time in a cold environment without being started, starting is more difficult because the engine oil is thick. The starting current is measured in amperes (A), representing the flow that the battery can produce for a short period (about 10 seconds) to ensure the engine is started. In general, the starting current is directly proportional to the capacity of the battery, so a larger battery will also have a higher starting current.
The cold start-up current of the battery decreases as the battery ages, so the more significant the battery, the better. The level of the startup current of the car battery is chosen according to the cylinder capacity of the car and the type of fuel. In the case of diesel cars, the startup current of the car battery should be at least 750 A. For a gasoline car, a cell with a starting current of 450-580 A is sufficient.

The polarity of a suitable auto battery
Depending on this feature, the auto batteries are classified into positive-left auto batteries or positive-battery auto batteries. Mainly, vehicles have positive-drag polarity. Polar-positive and left-handed cars are rare, especially of Asian origin.
Positive polarity refers to the fact that the plus sign (+) is positioned on the right side of the battery. When you change your car battery, it is intended to keep the same polarity.
