Changshu Wanlong Power Technology R&D Co., Ltd., based in Changshu, Jiangsu, China, supplies this 12V 40AH sealed lead acid battery engineered for solar energy storage and deep cycle applications. The battery uses a Valve Regulated Lead Acid (VRLA) design with Absorbed Glass Mat (AGM) technology, which immobilizes the electrolyte to prevent spillage and allows for maintenance-free operation. Its stable 12-volt output is suited for off-grid systems requiring reliable charge-discharge cycles.
The battery construction features a lead dioxide cathode and a sponge lead anode, standard for this chemistry. The AGM electrolyte system contributes to lower internal resistance and better performance in cyclic applications compared to traditional flooded batteries. For the 40AH capacity class, typical industry dimensions are in the range of 197mm (L) x 165mm (W) x 175mm (H), though the supplier's exact model dimensions should be confirmed. The source data indicates a tolerance of ±2mm for length, width, and height measurements.
This battery is commonly sourced by integrators of solar power systems, telecommunications backup providers, and UPS manufacturers. It is designed for global export with standard international packaging. Trade specifics such as minimum order quantity, unit price, and shipping terms are not detailed in the listing and must be negotiated directly with Changshu Wanlong Power Technology to align with your project scale and logistics requirements.

When sourcing the 12V 40AH sealed lead acid battery from Changshu Wanlong Power Technology, first verify the exact physical dimensions and terminal type against your system's battery compartment. Request the full product datasheet, which should include detailed charge voltage specifications, internal resistance, and a capacity vs. discharge rate table.
Confirm all trade and logistics terms before finalizing the order. Key items include the minimum order quantity, price per unit for your volume, Incoterms (e.g., FOB Shanghai), production lead time, and payment terms. Since the supplier's response metrics are not active, initiate contact via their provided address and be prepared for a direct negotiation.
Upon receiving the goods, conduct incoming quality checks. Measure the open-circuit voltage of a sample battery; a fully charged 12V AGM battery should read between 12.8V and 13.0V. Perform a capacity test by discharging at a constant current (e.g., 2A for 20 hours) to verify it meets the 40AH rating. Inspect the terminals and casing for any shipping damage. These steps ensure the batteries meet your quality standards before integration or resale.
