II. Core Performance
Safety and Stability
Leak-proof and explosion-proof design, UL94V-0 flame retardant certification, no risk of electrolyte leakage or expansion 56;
Strong impact resistance: No abnormalities after dropping from a 20cm height onto hardwood 3 times 56;
Vibration resistance: No damage after 1 hour at 4mm amplitude and 16.7Hz frequency 57.
Discharge Performance
Stable discharge voltage with a flat platform, supports 2CA high-current discharge (5 minutes) and 10CA instantaneous discharge (5 seconds) 57;
Strong over-discharge recovery capability: Capacity recovery >75% after 3 weeks of constant resistance discharge at 25°C 56.
Long Lifespan and Environmental Friendliness
Float service life: 10 years (at 20°C) 13, cycle life exceeds 500 cycles (under 25°C maintenance conditions) 37;
Self-discharge rate <2%/month (at 25°C) 13, gel type offers better high-temperature resistance 48.
Environmental Adaptability
Operating temperature range: -20°C to 50°C 17;
Stable low-temperature startup performance, requires ventilation for heat dissipation in high-temperature environments 38.

IV. Usage and Maintenance Recommendations
Charging Management:
Recommended float charge voltage: 13.5~13.8V (at 25°C) 68, equalizing charge cycle ≤3 months 8;
Avoid overcharging (>14.4V) or deep discharge (termination voltage ≥10.5V) 56.
Storage Requirements:
Unused batteries must be stored below 20°C; at 30°C, recharge every 6 months 68;
Mixing different models or old and new batteries is prohibited 27.
Maintenance and Inspection:
Regularly check for terminal oxidation and loose connections, clean and apply anti-corrosion coating 58;
Immediately stop use and inspect if abnormal heating or voltage drop occurs 67.
V. Market and Certification
Reference Price: Approx. 200 RMB per unit (standard type, varies with purchase volume) 1;
Certification Standards: Complies with UL and CE certifications, meets green energy specifications 57.
