从China供应商批发进口12v Deep Cycle Gel Battery — FOB条款

This 12V deep cycle gel battery from Changshu Wanlong Power Technology R&D Co., Ltd. is a sealed VRLA (Valve Regulated Lead Acid) unit that uses a silica-thickened gel electrolyte instead of liquid acid, preventing spillage and enabling operation in any orientation. The supplier lists models ranging from 7AH to 250AH capacity, with dimensions varying accordingly from compact 152mm x 65mm x 98mm units up to larger 520mm x 270mm x 225mm formats. The battery housing is constructed from ABS, providing structural rigidity and resistance to acid corrosion.

Gel electrolyte technology offers distinct advantages over standard flooded lead-acid and even AGM (Absorbed Glass Mat) batteries for deep cycling applications. The gel suspension reduces acid stratification and plate sulfation, which are the primary causes of premature failure in batteries subjected to repeated deep discharges. Typical cycle life for quality gel batteries ranges from 500 to 1,200 cycles at 50% depth of discharge, significantly outperforming conventional starting batteries that degrade rapidly under deep cycling. The sealed design also means zero maintenance, no topping up of electrolyte, and minimal gassing during charging.

These batteries are widely sourced by importers serving the solar energy storage, UPS (uninterruptible power supply), telecommunications backup, and marine/RV markets. The 12V format is the most common voltage for off-grid solar systems and backup power installations globally, creating consistent demand across Africa, Southeast Asia, the Middle East, and Latin America. Buyers should note that the listing does not specify MOQ, pricing, or certifications, so importers need to contact Changshu Wanlong directly to confirm compliance with IEC 60896 (stationary lead-acid batteries) or equivalent standards and to negotiate bulk trade terms.

Changshu Wanlong Power Technology R&D Co., Ltd. is located in Changshu City, Jiangsu Province, China, at No. 2, Fuchunjiang East Road, Southeast Economic Development Zone. Changshu is a well-established manufacturing hub in the Yangtze River Delta region, with strong logistics connections to Shanghai port, which is one of the largest export terminals in the world. The supplier holds a 'harbor' trust tier on the platform, indicating basic registration, but no response rate or response time data is available to assess their communication reliability.

The listing presents a range of 12V gel battery models from 7AH to 250AH, along with a 24V 130AH model, suggesting the company has production capability across multiple capacity sizes. However, the listing does not disclose the company's founding year, factory size, workforce, annual production volume, or export history. Buyers should request verifiable documentation such as ISO 9001 quality management certification, IEC 60896 test reports, and factory audit results before committing to supply agreements.
