| Battery Discharging Characteristics: The discharging capacity of the battery depends on the discharge rate being used and ambient temperature. 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. |
Open Circuit Voltage and Residual Capacity Residual capacity can be estimated by measuring the open circuit voltage as the picture. |

| Effect of Temperature on Capacity At a higher temperature, the capacity of battery increases and conversely at a lower temperature, the capacity of battery decreases. The pictures shows the effects of different temperature in relation to battery capacity. |
Self-discharge Characteristics The time for the capacity to decrease to 50% of nominal capacity at each temperature during storage. If the storage temperature is known, the graph may be used for finding the most useful recommended refresh charge intervals. |

| Effect of Temperature on Charging Voltage As temperature rises, electrochemical activity in the battery increases. Similarly, as temperature falls, electrochemical activity decreases. Therefore, as temperature rises, charging voltage should be reduced to prevent overcharge, as temperature falls, charging voltage should be increased to avoid undercharge. In general, to assure optimum service life, use of a temperature compensated charger is recommended. The picture shows the relationship between temperatures and charging voltages in both cyclic and standby applications. |
Constant Voltage Charging Standby service: 2.23-2.30 vpc at 20oC(68oF) to 25oC(77oF) Cycle service: 2.40-2.50 vpc at 20oC(68oF) to 25oC(77oF) It is suggested that the initial current be set within 0.4CAmps. The charging current is decreased to approx 0.5-4mA/Ah under charging voltage 2.30 vpc, and 3-10mA/Ah under charging voltage 2.40vpc when the battery is fully charged at 20oC(68oF) to 25oC(77oF). Note: it is necessary to ensure that the voltage is correctly set. The charging voltage set too high will increase the corrosion of the positive plates causing loss of capacity and ultimately shortening the life of the battery. |
||
| Cyclic Life Giving due consideration to the above factors, the actual life of a battery in cycle service is dependent on the depth of discharge of each cycle. The greater the depth of discharge of each cycle, the less the number of cycles available from the battery. |
Standby Life The estimated life under float service of FP type is 7 years at 20oC/68oF; LFP type is 12 years at 20oC/68oF; CFP type is more than 20 years at 20oC/68oF. The float service life is affected by the factors listed above and the number of discharging, the depth of discharging the battery suffers during its life time. The more discharges suffered and the deeper the discharges, the shorter the battery life. The higher the temperature, the shorter the battery life. If the battery temperature remains at an elevated level for an extended period of time, the expected life is reduced by 50% for each 8 to 10oC of constant temperature above 20oC/68oF. |
