Key Performance Features

Discharge Characteristics

• Constant Current: Provides detailed discharge currents from 10 minutes up to 20 hours at termination voltages 1.60–1.85V/cell (25°C)

• Constant Power: Delivers corresponding power output across different durations and termination voltages

Lifetime & Reliability

• Cycle Life vs Depth of Discharge (DOD):

  • 50% DOD: up to 3000 cycles

  • Lower DOD extends cycle life significantly

• Temperature Effects on Capacity:

  • At 0°C: ~85% capacity

  • At 40°C: ~108% capacity

• Temperature Effects on Float Life:

  • Every 10°C increase in temperature reduces float life by ~50%

Maintenance & Usage Notes

• Self-Discharge Rate: <2% per month at 20°C; after 6 months at 25°C, recharge recommended

• Housing Material: ABS (UL94-HB standard; optional UL94-V0 flame retardant)

• Temperature-Compensated Charging: Adjust float/cycle charge voltage based on ambient temperature

• Capacity Testing: Requires full charge before testing; C10 capacity reaches 95% after first cycle and 100% after third cycle

Safety & Compliance

• Designed for long-term cyclic applications with superior reliability

• Ideal for solar energy systems, communication base stations, and UPS applications

• Company reserves the right to modify technical parameters without prior notice
