Overview

Weishen Battery is a prominent Chinese brand specializing in lead-acid and lithium-ion batteries for industrial and automotive applications. Established with a focus on R&D, the company adheres to international standards like ISO 9001, ensuring consistent quality. Its product range includes starter batteries for vehicles, deep-cycle batteries for renewable energy systems, and backup power solutions for telecommunications. Known for competitive pricing and durability, Weishen batteries are widely used across Asia, Africa, and South America. The brand emphasizes eco-friendly production processes, with some models featuring recyclable components. B2B buyers often partner with Weishen for OEM/ODM services, catering to specific voltage and capacity requirements.

Structure and Working Principle

Weishen's lead-acid batteries consist of lead dioxide (positive plate), sponge lead (negative plate), and sulfuric acid electrolyte. During discharge, chemical reactions convert stored energy into electricity, reversing during charging. Advanced models use AGM (Absorbent Glass Mat) or gel technology to prevent leakage and enhance vibration resistance. Lithium-ion variants employ LiFePO4 chemistry, offering higher energy density and faster charging. Both types integrate safety mechanisms like pressure relief valves and thermal sensors. The modular design of industrial-series batteries allows parallel/series connections for customized voltage and capacity configurations.

Key Features

Weishen batteries are engineered for harsh conditions, with a typical operating temperature range of -20°C to 60°C. Their lead-acid models boast a 300–500 cycle life at 80% depth of discharge, while lithium-ion versions exceed 2,000 cycles. The corrosion-resistant ABS casing and sealed construction minimize maintenance needs. Smart batteries with built-in Battery Management Systems (BMS) provide real-time monitoring of voltage, current, and temperature. Unique grid designs optimize active material utilization, ensuring stable performance under high-load scenarios such as solar inverters or forklifts.

Application Areas

Automotive: Widely used in trucks, buses, and motorcycles as starter batteries, particularly in markets with extreme weather conditions. Industrial: Powers forklifts, mining equipment, and railway signaling systems due to shock-resistant designs. Renewable Energy: Solar/Wind storage batteries feature deep-cycle capabilities for off-grid installations. Telecom: Backup power for base stations, often configured in 48V systems. UPS: Emergency power supply for data centers and medical facilities, with fast recharge times.

Maintenance and Precautions

For lead-acid batteries, periodic checks of electrolyte levels (for flooded types) and terminal cleaning are recommended. Equalization charging every 3–6 months prevents sulfation. Lithium-ion models require no watering but should avoid storage at full charge to prolong lifespan. Always use compatible chargers with voltage/current limits matching battery specifications. Install in well-ventilated areas away from sparks. Dispose of end-of-life batteries through certified recyclers to comply with hazardous waste regulations like the EU Battery Directive.

B2B Procurement Guide

Bulk buyers should verify certifications (e.g., CE, UL, or GB/T) and request sample testing for capacity validation. MOQs typically start at 100 units, with lead times of 15–30 days for customized orders. Key documentation includes MSDS, warranty terms (usually 12–24 months), and shipping classifications (UN2794 for lead-acid). Negotiate Incoterms (e.g., FOB Shanghai) and clarify after-sales support, including technical training for installation. For projects in humid climates, opt for anti-corrosion terminal coatings. Compare C5 vs. C20 rated capacities to accurately assess runtime under different loads.
