About Changshu Wanlong Power Technology R&D Co., Ltd. - Batteries & Chargers Supplier in China

Changshu Wanlong Power Technology R&D Co., Ltd. is based in China and currently lists five active products in its catalogue. The company focuses on the Batteries & Chargers segment and provides a range of sealed lead‑acid batteries with capacities from 40 Ah to 100 Ah at a nominal 12 V. Product entries include a 12 V 40 Ah solar lead‑acid sealed battery (HS 8507.20), a 12 V deep‑cycle gel battery (HS 8507.20), a 12 V 55 Ah AGM forklift battery (HS 8507.10), a 12 V 100 Ah lead‑carbon battery (HS 8507.20) and a generic lead‑acid battery (HS 8507.20). Each item specifies the internal chemistry, such as lead‑dioxide cathode, sponge lead anode, AGM or gel electrolyte, and the material composition is detailed in the catalogue. The HS codes place all items under Chapter 85, heading 8507, which covers electric accumulators.

The catalogue distinguishes the electrolyte and separator technology: the gel battery uses a silica‑gel electrolyte housed in ABS, the AGM model employs an absorbed glass‑mat separator, and the carbon‑enhanced version incorporates a lead‑carbon composite anode. The forklift battery is classified under HS 8507.10, the sub‑heading for lead‑acid batteries designed for automotive or industrial use, while the remaining four items fall under HS 8507.20, the sub‑heading for other lead‑acid accumulators. No additional product lines beyond these five items are listed, and the supplier’s trust tier is marked as “harbor” in the source data. This factual snapshot defines the current scope of Changshu Wanlong Power Technology R&D Co., Ltd.’s offerings.

Product Range and Specialties of Changshu Wanlong Power Technology R&D Co., Ltd.

The listed products cover four principal lead‑acid technologies: flooded (standard), gel, AGM and lead‑carbon hybrid. In global trade, flooded solar batteries are typically rated to IEC 60896‑1, offering cycle lives of 400‑600 cycles at 0.2 C discharge and a temperature range of - 20 °C to 45 °C. Gel batteries are built to IEC 60896‑3 standards, providing deep‑cycle capability with typical cycle lives of 500‑800 cycles and a higher tolerance for deep discharge. AGM batteries for forklift or industrial use usually conform to IEC 60896‑2, featuring low internal resistance and a recommended C‑rate of 0.5 C to 1 C, with vibration‑resistant construction. Lead‑carbon batteries combine a carbon‑infused positive plate with traditional lead‑acid chemistry, delivering improved charge acceptance and cycle life (often 700‑1000 cycles) and are increasingly used in renewable‑energy storage. Typical specifications include a nominal voltage of 12 V, capacity tolerance of ±5 %, self‑discharge below 3 % per month, and a recommended charging voltage of 14.4 V for AGM and 14.6 V for gel types.

Trade and Export Information - Changshu Wanlong Power Technology R&D Co., Ltd.

China is one of the largest exporters of sealed lead‑acid batteries, and the HS 8507 heading captures the bulk of global shipments. Major import regions for these batteries include Southeast Asia, the Middle East, Africa and the European Union, where they are used in solar PV systems, material‑handling equipment and backup power. Buyers generally require compliance with IEC 60896 series, UN 38.3 testing for safe transport, and, for EU destinations, CE marking and RoHS conformity. Packaging is usually in wooden crates or ISO‑standard pallets, with a typical 20‑ft container holding 30‑40 units of 12 V 40‑100 Ah batteries depending on packaging. Freight terms often use FOB Shanghai or CIF destination port, and carriers must follow IATA/DGR or IMDG regulations because lead‑acid batteries are classified as Class 9 hazardous material due to corrosive electrolyte.

Sourcing from Changshu Wanlong Power Technology R&D Co., Ltd. - Buyer Guidance

When sourcing from Changshu Wanlong Power Technology R&D Co., Ltd., request an IEC 60896 test report that confirms capacity, cycle life and safety parameters for the specific battery type. Obtain a Material Safety Data Sheet (MSDS) that details the handling of sulfuric acid electrolyte and any hazardous waste disposal requirements. Verify that the supplier can provide a certificate of conformity for the relevant standard (e.g., IEC 60896‑1 for flooded, IEC 60896‑3 for gel, IEC 6087‑2 for AGM) and that the batteries are packed according to UN 38.3 and IMDG guidelines. Confirm the packaging dimensions, pallet configuration and container loading plan to ensure efficient logistics, and ask for a sample or a pre‑shipment inspection report if the order exceeds a single container.

What lead‑acid battery technologies are listed by Changshu Wanlong Power Technology R&D Co., Ltd.?

The catalogue includes a standard flooded solar battery, a deep‑cycle gel battery, an AGM battery for forklift use, a lead‑carbon hybrid battery and a generic lead‑acid battery, each with a nominal 12 V output.

Which HS codes apply to the supplier’s batteries?

Four of the products are classified under HS 8507.20 (other lead‑acid accumulators), while the 12 V 55 Ah forklift AGM battery falls under HS 8507.10 (lead‑acid batteries for automotive or industrial use).

What material composition is specified for the 12 V 40 Ah solar battery?

It uses a lead‑acid chemistry with a lead‑dioxide cathode, sponge lead anode and an absorbed glass‑mat (AGM) electrolyte, as described in the catalogue.

Which industry standards are typically required for these battery types?

Flooded and solar batteries usually meet IEC 60896‑1, gel batteries IEC 60896‑3, AGM batteries IEC 60896‑2, and lead‑carbon batteries are often validated against IEC 60896‑1 with additional cycle‑life testing.

What certifications should a buyer request before purchase?

Buyers should request IEC test reports, UN 38.3 transport certification, an MSDS, and, for EU shipments, CE marking and RoHS compliance.

How are the batteries typically packaged for export?

Export shipments are commonly packed in wooden crates or on ISO pallets, with a typical 20‑ft container holding 30‑40 units depending on battery size and protective cushioning.
