Capacity
Capacity is measured quantitatively in ampere-hours delivered at a specified discharge rate to a specified
cut-off voltage at room temperature. The cut-off voltage is 1.0 volt per cell.
Battery available capacity depends upon several factors including such items as:
1. Cell design (cell geometry, plate thickness, hardware, and terminal design govern performance under
specific usage conditions of temperature, discharge rate, etc.).
2. Discharge rate (high current rates yield less capacity than low rates).
3. Temperature (capacity and voltage levels decrease as battery temperature moves away from the 60°F
(16°C) to 90°F (32°C) range toward the high and low extremes).
4. Charge rate (higher charge rates generally yield greater capacity).
