125 Ah ÷ 0.8 = 156.25 Ah (note that the actual energy required by the load was 75 Ah).
It will be seen from the above that the final rated capacity of the batteries is almost
2 times the energy required by the load in Ah. Thus, as a Rule of Thumb, the Ah
capacity of the batteries should be twice the energy required by the load in Ah.
7.17 CHARGING BATTERIES
Batteries can be charged by using good quality AC powered battery charger or from alter-
native energy sources like solar panels, wind or hydro systems. Make sure an appropriate
Battery Charge Controller is used. It is recommended that batteries may be charged at
10% to 13% of their Ah capacity (Ah capacity based on C-Rate of 20 Hr Discharge Time).
Also, for complete charging (return of 100% capacity) of Sealed Lead Acid Battery, it is
recommended that a 3 Stage Charger may be used (Constant Current Bulk Charging Stage
}
Constant Voltage Boost / Absorption Charging
}
Constant Voltage Float Charging).
In case, Wet Cell / Flooded Batteries are being used, a 4-stage charger is recommended
(Constant Current Bulk Charging Stage
}
Constant Voltage Boost / Absorption Stage
}
Constant Voltage Equalization Stage
}
Constant Voltage Float Stage).
