If the car engine is the heart that produces movement, car batteries are the lungs that help the entire system work. To this day, a vehicle cannot be mobilized without the energy provided by the battery. Basically, today there are five types of car batteries and you can choose the one that best suits your needs and budgets, check here, car battery price
types of car batteries
It is worth noting that each one requires a particular type of maintenance. The first three types we’ll look at (wet cell, calcium, and AGM) are lead-acid batteries. This has many advantages and disadvantages, which we will see below.
wet cell battery
They are the most popular due to the low price. We can find this battery for about 40 euros. While others cost a few hundred Euros. Depending on the strength of the current and the brand that is purchased.
They work with lead plates with anode and cathode, freely suspended in sulfuric acid. The tiles are isolated from each other. And there is a soldered negative plate additionally to avoid damage to the positive plates. They are virtually maintenance free (although unfavorable weather can affect their lifespan) and when they fail, they are replaced without further concern.
Calcium car batteries
This type is also quite common, its principle of operation is almost the same as that of a liquid electrolyte battery, but the difference is that the plates are made of calcium alloy. This has two main advantages: prevents plate corrosion and allows up to 80% less liquid loss (self discharge).
They have a much longer lifespan than your wet cells. Something important to consider is that you have to be careful not to overload them as they can be permanently damaged. Their prices are also quite low due to their popularity, a little more expensive than the previous ones but not more.
VRLA car batteries (AGM and GEL)
VLRA stands for “Valve Regulated Lead Acid,” which refers to the pressure relief valves inside the battery compartment. This means that you cannot lose liquid because the gas is under pressure in a liquid state. There are two such designs: AGM and GEL.
Often referred to as “dry” car batteries, AGM batteries separate the electrolytes with fiberglass, creating a small amount of internal resistance and keeping them stationary. With this system, you do not use water or gel. This is cutting edge technology in the world of lead-acid batteries. It should be noted that these are high power car batteries, even if their size is lower, so they are used as batteries to start the engine.
The gel battery is named for they use silicon to make the acid thicker, in the form of a gel. These batteries have a very good deep discharge capacity, making them ideal for vehicles with demanding electrical equipment. But they are not recommended for starting the engine. The price of the first starts from 40 euros, the second – from 80 euros.
deep cycle battery
Deep cycling can provide power for a long time, but it also discharges much faster. The difference between these batteries is that they have thicker plates than others.which increases its carrying capacity.
We often find them in electric cars and other types of vehicles that actively use electricity. They are also widely used in the renewable energy industry to store energy prior to distribution. These are very expensive batteries and their prices start at 150 euros.
lithium ion (Li-Ion) car batteries.
This layer is like the one we can find in mobile phones, laptops, cameras, etc. But with a much larger size for car use. This type of battery uses lithium salts to function. They have a built-in overload protection circuit. A small drawback is its lower performance at low temperatures than the rest. Its autonomy is very good and the weight is much lighter than the rest, as well as the price.
