Lead-acid batteries, a common type of rechargeable battery, rely heavily on the selection of their outer shell, as it directly impacts the battery's safety, durability, and performance. When choosing the shell for lead-acid batteries, common options include ABS conventional shells and ABS flame retardant shells, while also considering materials like polyethylene (PE) and polypropylene (PP).   **Characteristics of ABS Battery Shell:**   - **High Strength and Impact Resistance:** ABS materials offer outstanding physical strength and impact resistance, effectively safeguarding the internal structure of the battery. - **Corrosion Resistance:** ABS materials exhibit excellent chemical stability and corrosion resistance, ensuring long-term stability even in harsh environments. - **Lightweight:** ABS materials are lightweight and easy to process, contributing to reducing the overall weight of the battery and facilitating production. - **Insulation Performance:** ABS materials provide good insulation performance, helping prevent damage to the environment or individuals from the battery shell.   **Advantages of ABS Flame Retardant Shell:**   - **Compliance with UL94 Standards:** ABS flame retardant shells typically choose materials with V-0 grade to minimize the risk of fire. - **Fire Safety Assurance:** In locations where fire safety requirements are high, ABS flame retardant shells provide additional protection, ensuring the battery can operate safely in unexpected situations.   **Comparison with PE&PP Battery Shells:**   - ABS offers higher physical strength and impact resistance, as well as better chemical stability, enabling stable operation in harsher environments. - Compared to PE/PP, ABS has superior wear resistance and surface finish, prolonging the shell's lifespan and providing better aesthetic effects.   When selecting the outer shell for lead-acid batteries, customers can choose to use ABS battery shells according to their actual needs, with ABS flame retardant shells suitable for locations with high fire safety requirements. Compared to PE and PP, ABS offers superior performance, ensuring the long-term stability of the battery's operation.
