New Energy 18650/AA/AAA Battery Steel Shell – 3.7V Pre-Nickel Plated Cylindrical Lithium Battery Accessories

Product Overview

Our pre-nickel plated cylindrical battery steel shells are key accessories for 3.7V new energy lithium batteries, available in 18650, AA, and AAA models. Crafted from high-grade cold-rolled steel with advanced nickel-plating technology, they combine structural robustness, corrosion resistance, and reliable electrical performance. Designed to protect battery cores and ensure stable operation, these shells are widely trusted in consumer electronics, household appliances, and new energy device manufacturing.

Key Product Features

Pre-Nickel Plated Surface: Uniform nickel coating (thickness: 0.5-2μm) enhances solderability and anti-corrosion, ensuring long-term electrical contact stability.
High-Strength Material: Cold-rolled steel (SPCC grade) offers excellent hardness (HV ≥ 180) and impact resistance, preventing core deformation from external forces.
Precision Dimensional Control: CNC processing ensures tight tolerance (±0.02mm), enabling perfect matching with battery cores and aluminum-plastic films.
Leak-Proof Design: Smooth edge and consistent wall thickness optimize sealing performance during battery assembly, avoiding electrolyte leakage.
3.7V Voltage Compatibility: Tailored for 3.7V cylindrical lithium batteries, adapting to the working parameters of mainstream new energy devices.
