Performance Features
- Safety and Reliability: Adopts a highly reliable dual-seal structure for the pole, with excellent impact resistance and sealing performance, ensuring no electrolyte leakage¹. Equipped with a domestic explosion-proof acid-filtering plate safety valve, which has an appropriate opening and closing pressure, featuring explosion-proof and acid mist filtering functions. It can release excess gas during overcharging to prevent battery expansion and cracking, as well as acid mist escape¹.
- Excellent Performance: Uses pure raw materials and additives, as well as electrolyte with a special formula, resulting in low internal resistance, good high-rate characteristics, and strong charging acceptance¹. The electrolyte is made of American fumed silica, presenting a gel state in the finished battery, non-flowing, with no leakage or electrolyte stratification¹. The battery has a large heat capacity, reducing the risk of thermal runaway, is not easy to dry up, and can be used in harsher environments³.
- Resistance to Various Working Conditions: Good vibration resistance: After a fully charged battery is fixed, it is vibrated for 1 hour with an amplitude of 4mm and a frequency of 16.7Hz, with no leakage, no battery expansion or cracking, and normal open-circuit voltage². Good impact resistance: A fully charged battery is naturally dropped 3 times from a height of 20cm onto a 1cm-thick hard wooden board, with no leakage, no battery expansion or cracking, and normal open-circuit voltage². Good over-discharge resistance: A fully charged battery is discharged at a constant resistance for 3 weeks at 25℃, with a recovery capacity of over 75%². Good charge resistance: A fully charged battery is charged at 0.1C₁₀ for 48 hours at 25℃, with no leakage, no battery expansion or cracking, normal open-circuit voltage, and a capacity retention rate of over 95%².
Application Fields³
