Preface
=======

Many books have been written on Storage Batteries used in stationary
work, as in electric power stations. The storage battery, as used on
the modern gasoline car, however, is subjected to service which is
radically different from that of the battery in stationary work. It is
true that the chemical actions are the same in all lead-acid storage
batteries, but the design, construction, and operation of the starting
and lighting battery, the radio battery, and the farm lighting battery
are unique, and require a special description.

Many books have been written on Storage Batteries used in stationary
work, as in electric power stations. The storage battery, as used on
the modern gasoline car, however, is subjected to service which is
radically different from that of the battery in stationary work. It is
true that the chemical actions are the same in all lead-acid storage
batteries, but the design, construction, and operation of the starting
and lighting battery, the radio battery, and the farm lighting battery
are unique, and require a special description.

This book therefore refers only to the lead-acid type of starting and
lighting battery used on the modern gasoline Automobile, the batteries
used with Radio sets, and the batteries used with Farm Lighting
Plants. It is divided into two sections. The first section covers the
theory, design, operating conditions, and care of the battery.

The second section will be especially valuable to the battery
repairman. All the instructions given have been in actual use for
years, and represent the accumulated experiences of the most
up-to-date battery repair shops in the United States.

The first edition of this book met with a most pleasing reception from
both repairmen and battery manufacturers. It was written to fill the
need for a complete treatise on the Automobile Storage Battery for the
use of battery repairmen. The rapid sale of the book, and the letters
of appreciation from those who read it, proved that such a need
existed.

The automobile battery business is a growing one, and one in which new
designs and processes are continually developed, and in preparing the
second and third editions, this has been kept in mind. Some of the
chapters have been entirely re
