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.
1.14.15 Charging batteries
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 appropriate battery
Charge Controller is used. It is recommended that batteries may be charged at 10% to 20%
of their Ah capacity (Ah capacity based on 20 Hr Discharge rate). Also, for complete charging
(return of 100% capacity), it is recommended that 4-Stage Charger may be used as follows:
normal Charging (3-Stages)
Stage 1 (bulk Stage at constant current)
"
Stage 2 (Absorption Stage at constant
voltage)
"
Stage 3 (float Stage at constant voltage)
equalization Charging (4-Stages)
Stage 1 (bulk Stage at constant current)
"
Stage 2 (Absorption Stage at constant voltage)
"
Stage 3 (Equalization Stage at constant voltage)
"
Stage 4 (float Stage at constant voltage)
