Discharge Characteristics

The document provides detailed constant current (Ampere) and constant power (Watt) discharge tables at 25°C (77°F) for various time intervals ranging from 5 minutes to 20 hours. Key points include:

• Current discharge values (in Amperes) decrease as discharge time increases, e.g., from 18.00 A at 5 minutes to 0.26 A at 20 hours.
• Corresponding power discharge values (in Watts) also decrease with time, e.g., from 190.80 W at 5 minutes to 2.89 W at 20 hours.
• Multiple voltage levels are considered for discharge curves, including nominal voltages from 9.60 V to 11.10 V.

Capacity and Temperature Effects

Capacity varies with temperature and discharge rate:

• At 25°C (77°F), the rated capacity is 5.0 Ah at 20-hour rate.
• Capacity decreases at higher discharge rates: 4.60 Ah at 10-hour rate, 4.25 Ah at 5-hour rate, and 3.00 Ah at 1-hour rate.
• Temperature impacts capacity retention: 102% at 40°C (104°F), 100% at 25°C (77°F), 85% at 0°C (32°F), and 65% at -15°C (5°F).

Self-Discharge and Storage

• Capacity retention after storage at 25°C (77°F): 91% after 3 months, 82% after 6 months, and 64% after 12 months.

Charging Parameters

• Initial charging current should be less than 2.0 A.
• Recommended charging voltages: 14.40-14.70 V for cycle use, 13.50-13.80 V for float charging.
