foR 12V BATTERY:
500 Ah ÷ 0.8 = 625 Ah (note that the actual energy required by the load was 300 Ah).
foR 24V BATTERY:
250 Ah ÷ 0.8 = 312.5 Ah (Note that the actual energy required was 150 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.

batteries can be charged by using good quality AC powered battery charger or from
alternative energy sources like solar panels, wind or hydro systems. Make sure an ap-
propriate 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).
