About ESG

With the development of economy and the improvement of people’s living standard environmental protection has become a common theme of human being. More and more countries focus on the carbon emission from manufacturing industry, so ESG stands out from "TOYO" with over 30 years experience of battery industry to act on international convention.As ESG promotes intellectualized reform and digital transformation, Currently there are production bases in various cities of Guangdong for manufacturing SLA batteries and lithium batteries, which also extends to the field of new energy products.ESG has more than 30 senior engineers from YUASA TOYO with upgraded automatic intelligent production lines, so the staffs have been reduced from 3,000 to more than 1,000 people. The main materials and manufactures of ESG battery include alloy preparation, plate production, battery shell, separator production, all in one-stop manufacturing to ensure the stable and reliable quality of battery with better cost performance.ESG factory has invested more than 3 million US dollars in new tech. The battery lead plate’s production equipment is the most advanced in China. As a core component of battery the improvement of lead plate technology is conducive to the consistency and stability for each battery. According to experimental testing, ESG lead plates have no corrosion points, so battery life has been extended by 30%, which has got national patents and the attention of major media. ESG company follows the principle of customer first, and we are committed to build one-stop service team from technology development to production and sales for global markets. With our capability of professional leading technology development and high efficient stable customer service, over 50,000 batteries are manufactured here everyday. Meanwhile, we also design complete off-grid system with suitable solutions for users and regular clients all over the world. We are devoted to the faith of creating a home of green environmental protection, and provide super energy storage services with excellent quality, focus on the development of renewable industry from lead-acid batteries and lithium batteries to new energy products like inverters, wind turbines, power stations. Therefore, from mini portable energy storage to large-scale off-grid wind solar hybrid power station projects, ESG has become a well-known brand in the industry for one-stop product development, production, sales and system solutions. With the expansion of business, ESG is optimizing the win-win cooperation model of agency dealers, and overseas bases have been established one by one around the world. ESG will help customers do market analysis after confirming and starting the long-term cooperation between us. Also will set up oversea warehouses in the local area for regular sales promotion and publicity with certain advertising.
