According to market feedback and users, as well as the feedback of netizens, Tianneng and Chaowei batteries have become worse and worse in performance and service life, and some netizens have even left messages in the comment area to use their own situation, roughly in a year or so, what is the reason? How to choose a durable battery when replacing it later?
In fact, these problems are also many old users who come to repair the car to consult me, and they are very concerned about the service life and endurance of the battery. Take the initiative to talk to me about the use of the battery, generally reflect that the quality of the replacement battery is indeed too poor, and it is less than half of the previous use, such a problem has been encountered by many car owners, how to improve it? Regarding the problems of netizens and customers, today Duo bin shared several details from the reasons why the battery is not durable, the choice of battery and the precautions for future use.
Feedback from netizens and repair customers on Tianneng and Chaowei batteries
Whenever the choice of electric vehicles and batteries is shared, there are many netizens in the comment area who will leave some of their use of Tianneng and Chaowei batteries, generally speaking, the previous battery is used for several years, and now the battery is used for one year, and the full-charge battery life is also less than the original, thinking that the quality of Tianneng and Chaowei batteries is getting worse and worse.
Some customers who often come to the store for maintenance, the most used batteries are Tianneng and Chaowei batteries, all think that these two types of batteries are big brands, the past reputation and fame are very loud, many car owners have used, more trust, so in the replacement of the time is also the first choice for this type of battery.
In the past two years, the quality problems of the replacement of Tianneng and Chaowei batteries are also more, and the after-sales service has done more than before, the main reason is that the performance of the battery is unstable, the quality has become poor, and there are more quality problems in the use of the shelf life, such as the battery charging for a few hours to change the lights, the endurance has dropped significantly, it has been used for about a year, and the endurance has dropped to more than half.
Some old customers also questioned our repairmen and shops when the battery was not durable, and thought that they had not replaced him with a good quality battery.
These problems are also the main problems faced by many repair shops, in order to retain old customers and attract more new customers, more methods have been made in battery selection, so that these concerns of customers are minimized, so that old customers still trust in the past.
The main reason why Tianneng and Chaowei batteries are not durable
There are two main problems with battery durability, the prohibition of cadmium and battery weight reduction.
The first aspect: the prohibition of the use of cadmium element, in 2012, a number of departments of industry associations formulated the "Lead Battery Industry Access Conditions" clearly stipulates that the existing lead-acid batteries and parts with cadmium content higher than 0.002% and arsenic content higher than 0.1% are eliminated according to national standards and strictly controlled. In recent years, environmental protection policies have been strengthened, various fields have carried out energy conservation and emission reduction to protect the environment, the cadmium element added to the battery is heavy d, the use of this element has strict regulations, battery companies began to gradually reduce the use of this raw material.
Why is cadmium added to the battery? What does it do? The addition of chromium to the battery can play an anti-corrosion role in the lead plate, better protect the corrosion of the lead plate, and make the lead plate more durable.
The second aspect: battery weight reduction, the battery produced in the past two years began to lose weight, I picked out 14 to 20 years of the same model of single battery weighing, in 17 years ago the weight of a single battery in 7.1 ~ 7.2 kg, 19 years after a battery weight of 5.6 ~ 6 kg, the whole group of batteries compared with the previous period reduced by about 3 kg. The biggest impact of battery weight reduction is the weight reduction of the lead plate inside, the lead plate is thin, the number of layers is less, which affects the number of battery charge and discharge times is reduced, the thinner lead plate corrosion resistance is weakened, the use time will be reduced, in the absence of cadmium element corrosion protection, the lead plate will be damaged faster, so the battery life is reduced, the service life is reduced.
2 simple and practical ways to choose a more durable battery
How to choose a more durable battery method? There have been many people in the industry to share, after combing and summarizing 2 simple and practical methods.
Method 1: Choose the middle and high-end batteries in the Tianneng and Chaowei series, and there are not many batteries produced by Tianneng and Chaowei in the past, and low-end and high-end two categories can be selected. The price disparity is large, and the use effect will be higher, but with the change of the battery production structure, a brand battery, the series of products separated is more, shortening the price gap, generally between 50 and 150 yuan, giving the owner more choice.
But it is more product classification, but customers choose batteries when more confused, often to the store or repair shop only to listen to the recommendation of the merchant, how to choose a good quality battery? I don't know much, I can only listen to the recommendations of merchants to choose, but I have encountered unsatisfactory effects in use.
Correct selection method: choose Tianneng or Chaowei's high-end batteries, such as Tianneng's long-distance running king, longevity king, Juneng king, black gold battery; Chaowei's Galaxy gold, black gold, graphene battery, etc., and the price gap with ordinary batteries is about 50 to 150 yuan, a group heavier than ordinary batteries, about 3.5 kg, can be used for more than a year.
Method two: choose a heavy battery, now the price of the battery sold on the market is low, the replacement of people is also more, the shop main push this battery, in line with some car owners who pay attention to the price. The weight reduction of this type of battery is relatively large, the density of the lead plate is small, the durability is reduced, and the endurance and service life are affected.
The battery weight in the high-end will be 3 to 4 kilograms heavier than the ordinary, and the endurance will be farther through the test of many car owners, the service life can be increased by 1 to 2 years, and the additional 50 to 100 yuan can be replaced, which is actually very cost-effective. When replacing the battery, choose the heavier one to be more durable.
Duo Bin suggested: choose a low-price battery, the weight will be reduced, the endurance will be reduced, and the service life will definitely be affected. You can ask the store what is the difference between a low-priced battery and a high battery? Take a look at the weight, and choose the one with the heavier weight.
It is understood that the quality of the above Tianneng and Chaowei batteries has declined, mainly due to changes in the raw material structure and weight reduction of the battery, which affects the battery life and service life. These understanding is clear, it is necessary to choose correctly, giving two methods, one is to choose the high-end battery, the other is to choose the battery in the weight, master these 2 points You replace the battery will be durable.
So, when you buy a car or replace the battery, are you willing to choose Tianneng or Chaowei battery? Which method was used? Welcome to leave a message to communicate.
