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 .


Discharging Current Final Discharging Voltage(VPC)
Up to 0.1CA 1.75
0.11-0.17CA 1.70
0.18-0.25CA 1.67
0.26-1CA 1.60
Above 1.1CA 1.30


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.
