We have been working on lead-acid batteries for 23 years, growing new batteries to protect every rid

At seven o'clock in the morning, you get on an electric car and take your child to school. At six o'clock in the evening, you ride it through the evening rush hour to get home to cook.For hundreds of millions of Chinese households, electric bicycles are not a "choice" but a necessity—for commuting, grocery shopping, and picking up and dropping off children.Ultimately, there are two words that determine whether this car can be relied upon: the battery. But the reality is that many owners have experienced such a bad thing: their new car has only been riding for more than a year, and the range has shrunk from "one charge for two days" to "one charge in half a day"; The battery shell was packed inexplicably, and the heart beat when charging; Not to mention in winter, when the temperature drops, the electricity seems to have been secretly taken half by someone. These problems are, in essence, battery quality failures. Long New Battery, which has been battling these "bad things" since it built its first battery in 2003, has been fighting against these "nasty things."

01 23 - Just Do One Thing



The starting point of Changxin battery was a battery factory in 2003 in Zhuji, Zhejiang Province. That year, the Mangtingfang Power Supply Electronics Factory in Zhuji City was established and produced the first battery. The story since then is a typical "survival of the one" entrepreneurial history: in 2006, a battery production base was established in Jiangxi, in 2011 Jiangxi Changxin Power Co., Ltd. was officially established and listed as a major dispatch project in Jiangxi Province, and in 2013, the entire relocation was completed and officially put into production... In the past 23 years, Changxin Battery has grown from a small factory to a group high-tech enterprise with a thousand acres of production and intelligent industrial park with a total investment of 1.5 billion yuan. Its three autonomous brands, "Long Xin," "Mantingfang" and "Mythology," each have characteristics and advantages, and their products cover many fields such as electric power vehicle batteries, energy storage batteries, power vehicle batteriees and other fields. In addition, Changxin is also one of the drafting units of the national standard "GB / T23636 - 2017 for lead-acid batteries." For 23 years, Changxin has not blindly pursued the wind, but has focused all its energy on the track of lead-acid power batteries. Why? Because we know better than anyone that the people who ride their electric vehicles through the streets every day need not fancy concepts, but a set of safe, durable, non-tampering batteries.

02 A good battery pack. How many steps do you have to pass?



Level 1: Safety Safety is the bottom line and the most underestimated advantage of lead-acid batteries. The chemical properties of the internal materials of lead-acid batteries are stable, and there is basically no risk of heat loss, but this does not mean that the lead-acid battery can be "laid flat" in safety design. The Long New Battery uses a valve-controlled seal and leak-proof design, with a uniquely designed safety valve. Once the air pressure inside the battery is raised to a certain value, the safety valve will automatically open the exhaust gas and then automatically close it to prevent air from entering the battery interior. The fully sealed anti-leakage structure makes it easier for the battery to leak fluid even if it is placed in any direction. To put it bluntly, when something goes wrong inside the battery, it can "digest" itself, significantly reducing the user's trouble of facing leaking fluid that corrodes the body and breaking the hood. For parents who have to pick up and drop off their children every day, the meaning of this design is not only peace of mind, but also peace of mind. Level 2: durability "The new battery runs far, the old one can't run" - this is the most common complaint among lead-acid battery users. The root of the problem is plate sulphide. When the lead-acid battery is not charged enough, the lead sulfate on the polar plate can not be completely converted, and the crystal hardening over time will irreversibly decrease the battery capacity. The new solution starts with the 'heart' part of the plate. The positive and negative poles of the Long New Battery are both forged using Refined Lead No. 1, the battery is stronger against oxidation and corrosion, low self-discharge, and long-lasting quality. In terms of processes, Changxin continuously optimizes the matrix formulation and solidification process, making the active material skeleton more solid, and greatly improving the battery life. Level 3: All around the clock, batteries lose power quickly in winter and are afraid of high temperatures in summer - this is the "seasonal disease" of lead-acid batteries. Long new batteries are optimized through wide temperature range technology, so that the battery can maintain a stable performance output under high temperature and low temperature environments.In the comparison test of electric bicycle lead-acid batteries released by the Jilin Provincial Consumer Association in 2025, the Changxin 6-DZF-12 model received a four-star rating in a low temperature environment of -25 ° C, and the low-temperature discharge performance performed well with other competing test products in the same batch.Whether you are delivering takeaways in the cold winter of the northeast or commuting in the scorching heat of the south, a new battery is not easily "thrown off" due to changes in the weather. Level 4: Spare the last point, which is what the average user cares most about: don't worry about it. Long-new batteries have a maintenance-free design, and the buttoned lid structure makes battery maintenance more convenient, without the need for regular rehydration and acidification like older batteries. Load the car and ride it's over. For users who "don't want to get upset, just want to ride with peace of mind," this is the true good battery.
Not making shrinking products is our bottom line
The lead-acid battery industry has an open secret: the same nominal "12Ah" battery, some of the actual capacity can run to 105%, and some may not even 90%. A slightly thinner plate, less lead paste, and a slightly lower electrolyte concentration - the cost is saved, but users will find that the range "collapses" after six months of riding. The bottom line of growing new batteries is: don't make inferior shrinking products. It's not just a slogan. Our positive and negative polarizers use Refined Lead 1; Our batteries undergo rigorous quality testing before they come out of the factory; Our internal quality management system is perfect, and we firmly grasp the key factors that affect the performance of our products.



Over the past 23 years, Changxin Battery has earned numerous accolades, including: a well-known brand in China's lead-acid battery industry, a five-star quality enterprise, an AAA-level quality credit enterprise, a Jiangxi famous product, and a Jiangxi Province specialized and new small and medium-sized enterprise. But these honors are far less tangible to the user than a simple experience - loading the car and riding on it for two or three years.
Each battery pack is a commitment to cycling safety
At the end of the day, batteries are the lifeblood of electric vehicles. It determines whether you get to work on time in the morning, whether you run out of electricity halfway when you pick up your kids from school, and whether you're worried about battery problems when you ride in the rain.
Changing a new battery doesn't do anything spectacular. We just took what a lead-acid battery was supposed to be doing seriously for 23 years. From the casting of the polar panel to the assembly of the battery, from the design of the safety valve to the optimization of the sealing structure, each step has a single purpose: to enable everyone who rides an electric car to set off peacefully and get home safely. Longer batteries and longer runs - longer life, longer range, longer warranty.
