Rugged 12V 250AH Solar Gel Energy Storage Battery Extra-Large Capacity Deep Cycle Efficient for Severe Environment Power Supply

12V 250AH lead-acid colloid solar energy storage battery: A large-capacity power solution for global B2B partners

In the era of global transition to renewable energy, 12V 250AH solar gel batteries have become the cornerstone technology for reliable power storage. It is designed to achieve outstanding performance, manufactured for long-lasting durability, and provides an excellent solution for solar systems, UPS backup power supplies and off-grid applications. For distributors and wholesalers seeking high-performance and high-profit products, this battery represents an excellent opportunity to take the lead in the highly competitive renewable energy market.

Outstanding cycle life: At an 80% discharge depth, its lifespan can reach over 1,500 deep cycle discharges, ensuring long-term value and reducing the total cost of ownership for end users

Wide temperature adaptability: Specifically designed for harsh environments, it can operate stably within a temperature range of -20°C to 40°C, making it suitable for both scorching deserts and extremely cold climates.

Outstanding charge retention capacity: An extremely low self-discharge rate of less than 3% per month allows the battery to maintain no significant power loss even after long-term storage, which is crucial for inventory management and seasonal use.

Maintenance-free and enhanced safety: With a sealed valve-regulated design and colloidal electrolyte, no water needs to be added to prevent acid leakage. Standing upright enables the battery to achieve higher efficiency

The core of outstanding performance stems from advanced colloid electrolyte technology. By fixing the sulfuric acid electrolyte through a three-dimensional silicone gel network, the battery completely eliminates the risks of acid stratification and leakage, and can achieve 100% safe operation even in tilted or vibrating environments.

Flexibility is the core advantage for bulk purchasing and OEM projects. We offer customizable services: terminal types (lead, copper) are selectable, the housing can be engraved with our own brand, and the discharge rate can be adjusted according to the regional market demand. The minimum order quantity (MOQ) is only 5 units. They can be dispatched promptly via Shenzhen/Guangzhou Port, with an average delivery time of only 7 to 15 working days. Each batch of products has passed CE, FCC, ROHS and MSDS certifications, enhancing their credibility in the global market.

Currently, our batteries are selling well in African countries. To support your business development, we can grant you a regional patent sales license.

We guarantee that the battery is completely free of any impurities such as glass, and the quality of the battery can be guaranteed, reducing after-sales problems by 98%

We also have experienced engineers to provide you with professional solar energy solutions and technical support

Whether it's supplying power to off-grid villages, ensuring industrial backup power, or supporting large-scale residential solar systems, the 12V 250AH lead-acid gel solar energy storage battery is a reliable choice verified by data, helping you turn bulk orders into long-term business success.
