Learn about car batteries, how often should the battery be replaced?

On most types of transportation today, especially cars, the battery is an indispensable and important device. So choosing a quality battery is one of the important steps to keep your car running well. Through the following article, join CarOn to learn information about car batteries and how to maintain car batteries!

What is a car battery?

A car battery is a secondary power source or a type of battery, relying on the process of converting energy into electricity to store and power the car. With this type of battery source, users can use it many times by providing power through the charger system. In addition to being known as a car battery, it is also known by many names such as battery, battery, storage battery…

Structure and functions of car batteries

Structure

Car batteries consist of lead positive and negative plates arranged together and separated by partitions. The number of pairs of plates in each single battery is usually from 5 to 8 pairs. The poles on the same side are soldered together to form a compartment with a voltage of 2V.

*External structure of the battery

The external appearance of the battery has a cover (usually a plastic box). The battery shell is made from Acid-resistant Polypropylene plastic with very high durability. Normal water battery shells are opaque white and can be seen through. There are 2 lines indicating the MIN and MAX levels of the external Acid electrolyte solution. Dry battery cases come in many different colors depending on the battery brand.

In particular, the easiest way to identify a battery is that there are 2 protruding gray poles on top, which are the 2 positive and negative poles of the battery. Each pole will have notes of the same color:

  • Usually note the “+” sign on the surface of the tank shell and the red cap for the positive pole. The positive pile is larger in size than the negative pile.
  • Note the “-” mark on the tank cover for the positive pole and the accompanying black or blue cap.

*Internal structure of the battery

The structure of a car battery includes: negative (-) and positive (+) plates made of Lead (Pb) connected together by connecting rods and separated by partitions. The number of pairs of plates will usually be from 5 to 8 pairs. The poles on the same side will be soldered together and merged into a compartment with a voltage of 2V. Each compartment inside the battery will contain H2SO4 solution.

The frame of the plate is cast from lead with added (5 / 8%) Sb and shaped into a mesh, which helps increase conductivity and improve castability. In the active agent, there is about 3% additional blooming agent (organic salt) to increase the durability and stackability of the active agent layer.

To increase the energy storage capacity of a car battery, it is necessary to increase the number of pairs of plates.

Function

The battery is an extremely important part of the car, playing the role of storing and providing power in the car. When the engine has not started, the battery is the vehicle’s energy source, providing power for the engine starting process and providing power to the car’s auxiliary loads such as the lighting system, the electrical system. sound, … while the engine has not started yet. Probably the most important function of the battery is to provide power for starting the car engine.

Besides, batteries operate based on the process of converting chemical energy into electricity. To store electrical energy and supply it to electricity-using systems.

Should I use dry batteries or water batteries?

Currently, most car batteries use lead batteries. They are divided into two main types: sealed batteries (dry batteries) and open batteries (water batteries).

Advantages and disadvantages of dry batteries

*Advantage

  • Pre-filled with acid solution, fully loaded before leaving the factory. Customers who buy it just need to install it on their car to use it, and they don’t have to waste time on maintenance or refilling fluid.
  • Dry batteries can be used for a long time. If you don’t use it for a long time, you won’t have to worry about running out of power
  • Does not cause unpleasant odors because there is no gas produced outside
  • No regular maintenance required.
  • High charging current, after generating large current can recover voltage faster.
  • No need to add electrolyte during use
  • Applying many new technologies so it is highly durable and very strong
  • Cleaner and safer than water batteries because the surrounding metal is not corroded by acid vapor

*Defect

  • The price is more expensive than conventional batteries, many companies have to import them from abroad.
  • Power will suddenly run out, causing difficulties for users if they are on the road or have urgent work to do. However, experienced drivers say that car owners can prevent the car from running out of power by having a set of battery cables available in the car to use when needed.

Advantages and disadvantages of water batteries:

*Advantage

  • Water batteries have the advantage of high durability if properly cared for and maintained.
  • Their structure is simpler so their price is also quite cheap
  • Can be easily removed to use for other electrical equipment for lighting, cooling fans…
  • Even if left for a long time, the power can still be restored

*Defect

  • Must maintain regularly
  • Must recharge periodically, usually every 3 months if not connected to electrical appliances
  • When charging, it may cause gas to have an unpleasant odor
  • Has a lower lifespan than dry batteries
  • When the acid evaporates, it may cause rust inside the lid

How often do you need to replace your car battery?

Normally, if the car is regularly maintained and the battery charging system operates normally, the lifespan can last up to 100,000 km, equivalent to a usage time of 4 years. In fact, the lifespan of a car battery is only about 2-3 years. At the end of the battery life cycle, the battery needs to be replaced immediately.

Usually, according to customer statistics:

  • Vehicles running short distances periodically need to check the battery fluid every 3 months.
  • Vehicles driving long distances periodically need to check the battery fluid once every 0.5 months.

Note when using car batteries

During use, the car will appear a few signs so you can easily identify the condition of the battery. For example, the warning light on the smart screen lights up, the engine starts weakly, it is difficult to start in the morning, etc. You need to regularly check the battery to catch the problem early and come up with a solution. decide quickly. Batteries, after a period of use, are susceptible to conditions such as: low battery fluid level, battery swelling and leakage, etc.
