procedure should be followed? - ANSWER apply a sodium bicarbonate solution followed
by a fresh water rinse
What is the true statement about the hydrometer reading of a lead-acid storage battery
electrolyte? - ANSWER hydrometer reading does not need a temperature correction of
the electrolyte temperature is 80 F
What determines the amount of current which will flow through a battery while it is being
charged by a constant voltage source? - ANSWER the state of charge of the battery
Which of the following statements is/are generally true regarding the charging of
several aircraft batteries together? - ANSWER 1. Batteries of different voltage (but
similar capacities) can be connected in series's with each other across the charger, and
charged using the constant current method.
2. Batteries of unequal ampere-hour capacity and equal voltage may be paralleled with
one another, across the charger, and charged constant voltage method.
