4. Battery charging procedure
When charging a battery using DC genera¬
tion, the time required for charging will vary
with the size and charge state of the battery.
When the specific gravity of battery elec¬
trolyte is between 1.26 and 1.28, the battery is
in a fully-charged state.
It is advisable to check the specific gravity
every hour, if possible.
In the case of a 40AH battery for small-sized
automobiles, for instance, it will take 5 or 6
hours to bring it from a discharged state to a
fully-charged state. While charging, the elec¬
trolyte should be checked from time to time.
