3.1 Discharging
3.1.1 Final Discharging
Voltage
The final discharging voltage is the battery terminal voltage
in close circuit voltage per cell to which a battery discharging
safely and maximize battery life. The higher discharging current,
the lower final discharging voltage of battery .

3.1.2 Battery
Discharging Characteristics:
The discharging capacity of battery is depended on the
discharge rate being used and ambient temperature.
Figure 1,2 and 3 show the different discharging current
corresponding discharging capacity at 25oC(77oF)
for FP, LFP and CFP types batteries. They show that the
rated capacity of a battery is reduced when it is discharged
at a value of current that exceeds its 10-hours or 20-hours
rate.
3.1.3 Temperature Effects
in Relation to Battery Capacity.
At a higher temperature, the capacity of battery increases
and conversely at a lower temperature, the capacity of battery
decreases. Figure 4 shows the effects of different temperature
in relation to battery capacity.
