[YesAuto Model Shopping Guide] The reason for this survey comes from online discussions. Many netizens are enthusiastically discussing the phenomenon that individual manufacturers reduce costs by reducing battery capacity. Therefore, we have also launched random surveys and selected different models from the market. Look at the difference between them in the battery.

Before the comparison, I think we need to introduce the battery used in the car in the simplest terms.

What is a battery? What are the classifications?

The often said battery is also called a storage battery, which is a device that converts chemical energy into electrical energy. The battery in our vehicle is a starter battery. Divided into ordinary lead-acid batteries and maintenance-free batteries, the cost of lead-acid batteries is low, and distilled water needs to be added regularly to supplement the electrolyte for maintenance to ensure normal use. The other is a maintenance-free battery. As the name suggests, this battery does not need to be added with replenisher for maintenance, making it more convenient to use.

How to distinguish maintenance-free and ordinary non-maintenance-free batteries?

Since ordinary non-maintenance-free batteries need to be refilled with electrolyte, there is a protruding and unscrewed refill port at the top of the battery. The maintenance-free battery has the electrolyte enclosed in the battery when it leaves the factory, so the top of the battery is flat, even if there is a refill port, it is not easy to open, and it does not need to be opened during the life of the battery.

What is the function of the battery in the car?

The main function of the car battery is to provide sufficient power support for starting the vehicle, and secondly, to provide power support for the electrical appliances in the off state, and to maintain the power consumption of the dormant equipment during long-term parking. In addition, the battery also plays a role in stabilizing the circuit.

How does the manufacturer choose the battery for the vehicle?

As mentioned earlier, the main purpose of the battery is to start the vehicle, so the battery needs to meet the requirements of the ignition system. This is the most important function of the battery. As long as it meets the ignition, no matter how large the battery capacity is, it is qualified. In addition, it is necessary to consider the power consumption of the car's electrical appliances when it is sleeping. The more electrical appliances, computers, and sensors on the car, the greater the power consumption after the car is turned off, and a larger capacity battery is required. Manufacturers basically use these two points to decide how large a battery to use. Of course, the cost is also on the one hand. Small batteries will not have any effect on starting, but long-term parking will cause power attenuation and affect the car. The key point is long-term parking. Just like a mobile phone battery, a large capacity battery has a long standby time and a small capacity. The standby time is short. Of course, batteries with small capacity are cheaper, and maintenance-free batteries are more expensive than ordinary batteries.

This topic will continue, so the models that appear in this article will appear one by one in the future, which will cover all mainstream cars on the market, but the battery is related to the vehicle batch, and it is not ruled out that there will be discrepancies.


Before we start, we are going to explain a few data, these data need to be understood in order to understand the article

Rated voltage : the battery voltage is 12V under normal conditions, and the batteries of our household gasoline cars are basically 12V

Capacity: The unit of capacity is Ah (Ah), which is also the most important item we compare today, and it is also the focus of debate in the forum.

Low temperature starting current (CCA): In addition to the above two data, we have a label “CCA” on the battery, which indicates the starting current that the battery can provide to the engine when it is in a low temperature state. That is, the value is the current discharged by the battery before the limit feed voltage when the battery is discharged at -18°C for 30 seconds. This index has a lot to do with the technology and craftsmanship of the battery.

Reserve capacity (RC): indicates that when the charging system fails, the battery can provide the minimum time for the car load to work, that is, the value is the time (in minutes) for the battery to discharge at a current of 25 amperes to a termination voltage of 10.5 volts at 27°C .


Carnival 1.5L

Small cars are very popular in cities. As a sporty small car, Carnival has won a good reputation for its superior power and driving pleasure. Carnival has two models, 1.3L and 1.5L, and the sample we sampled today is 1.5L. .

The 1.5L Carnival uses a maintenance-free battery with a battery capacity of 52Ah and a cold-start discharge current of 500A under low temperature conditions. In addition, the Carnival battery is also marked with a reserve capacity (RC), which is to discharge at a current of 25A when the car is off. The time until the battery voltage reaches 10.5V, the time is 90min.

Swift 1.5L

The difference between Swift and Carnival is that it is a bit more warm after exercise. Many women value Swift. Swift also has two displacements of 1.3L and 1.5L. It happens that we found both of their batteries.

Regardless of the displacement, all the original Swifts are equipped with ordinary lead-acid batteries, which are not maintenance-free. It is necessary to check the consumption of the electrolyte from time to time and make timely replenishment. If you go to a 4S shop for maintenance, the battery electrolyte is a technician must check If you need to replenish one item, you will be able to raise the amount for free. The 1.3L Swift uses a small battery with a capacity of 35Ah, and the 1.5L version uses a large battery with a capacity of 45Ah.

MG6 1.8L

MG6 is relatively solid in its own brand in terms of model design and workmanship. MG6 takes the sporty route, especially this hatchback model is more popular with many young people. At present, MG6 has been on sale in the UK. Today, let’s take a look at 1.8L. What is the MG6 battery?

The MG6 battery is clearly marked in Chinese. The 1.8L model uses a maintenance-free battery with a battery capacity of 63Ah and a low-temperature starting current of 570A. It also indicates the reserve capacity. The discharge time is 110min in accordance with the prescribed standard. The battery has a protective cover, which can prevent dust and keep warm.

BYD F3 1.5L

Low price and high distribution have always been BYD’s sales strategy. Today, we will not discuss who it looks like and whether it will work after development on this road. Today we only look at the battery, the BYD F3 1.5L Platinum Edition.

BYD F3 uses a Camel brand battery with a battery capacity of 60Ah and a low-temperature cold start discharge current of 400A. The battery is a maintenance-free battery. The new F3 started to use Fengfan and Johnson batteries.

Golf 1.4TSI

The popularity of golf has not decayed so far, but a lot of discussions about Volkswagen's kindness and kindness are also going on, such as the material of the sunroof slide, the material of the subframe, etc. How about the battery?

The Golf 1.4TSI uses a Fengfan brand battery, which is maintenance-free, has a capacity of 60Ah, a low-temperature starting discharge current of 480A, and a voltage of 12V, of course. The battery is placed in a dustproof box.

Tiida 1.6L

Tiida has a lot of space, which has become a reason for many people to buy Tiida. Indeed, Tiida’s performance in compact home cars is outstanding, and the rear seats can also move forward and backward, but today we will look at the battery.

We found a 1.6L Tiida from 2008. The battery is a normal battery and needs to be checked regularly for electrolyte. From this point of view, we can't see any information about the battery, only the model number. After inquiry, we found that the battery capacity is 45Ah, and the low temperature starting current is 300A.

Octavia 1.6L

Octavia is also a compact car that focuses on home use, sharing technology with Sagitar, but the price is lower than Sagitar due to brand positioning, and the hatchback trunk design has become a major selling point. Today we found the 1.6L Octavia , Use its battery as a sample.

Octavia 1.6L uses a maintenance-free battery with a battery capacity of 60Ah and a cold start current of 480A at low temperatures. The battery is the same as that used in Golf.

Wing God 2.0L

Needless to say, Wingshen must take the sports route. The appearance attracts many young people. The front face that resembles EVO has a strong visual impact. What we got today is the 2.0L top equipped Wingshen as a sample for comparison.

The 2.0L Yishen uses an ordinary battery and needs to check the electrolyte regularly. The battery brand is Yuasa, with a capacity of 65Ah. The technician will also check the electrolyte during maintenance. If the price of rehydration at a loss is not high, it is about 20 yuan.

Yuedong 1.6L

The characteristics of Yuedong may not be so clear, and there is no place that can attract us at a glance. The balance of the middle is also a product feature that attracts consumers. Our Yuedong will be the representative of Korean cars.

The 1.6L Yuedong uses a maintenance-free battery, the battery brand is Fengfan, the capacity is 60Ah, and the low-temperature cold start discharge current is 550A, which is very different from the same level of models.

Roewe W5 3.2L

My colleague just finished the test drive of the Roewe W5. If you are interested, please click on the link to view “Road Comfort/Off-Road Test Drive Roewe W5 4WD SUV”. He also provided me with the battery data of the Roewe W5 as soon as possible.

Roewe W5 uses Valta brand battery, maintenance-free battery, capacity of 75Ah, low temperature cold start current of 630A, higher current, and reserve capacity of 130min.

to sum up:

We really cannot judge who is good and who is not the battery, because they can meet the normal start and use of the vehicle. These are all without any problems and meet the requirements. First of all, we must affirm that the electric capacity of these vehicles are all qualified. . However, there is a cost difference between them, especially between maintenance-free batteries and ordinary batteries, and the capacity is directly linked to the price, so manufacturers still consider the cost and the positioning of the model when matching the battery to the vehicle. This article is a series of articles and will continue. I believe that the cars you want to know will gradually appear in the article, so stay tuned . (Picture Car Home Zhang Ke)
