[Fig. 184 Rental battery card to be tied on car of customer]

File all the 5 by 8 cards (Part 3) in alphabetical order in a "dead"
ticket file, in either alphabetical or numerical order. With this file
you can build up an excellent mailing list of your customers. You can
note how many new customers you are securing and how many customers
are not coming back. The latter information is very valuable, as it
enables you to find out what customers have quit, and you can go after
them to get their repair business again.

When a rental is put on a card, the card shown in Fig. 184 may be tied
to the car where it is easily seen. This will serve as a reminder to
the customer and will help advertise your shop to those who ride in
the car.

Each rental battery should have a number painted on it in large white
letters, or should have attached to it at all times a lead tag on
which is stamped a number to identify the battery. To keep a record of
the rental batteries, a card or sheet similar to that shown in Fig.
185 may be used. Each time the rental is put on a car, a record is
made of this fact on the card. Each rental battery has its own card,
and reference to this card will show at once where the battery is.
Each card thus gives a record of the battery. The number of the rental
is also written on the Stock Card shown in Fig. 183, but the purpose
of putting the number on these cards is merely to make sure that the
battery is returned when the customer's battery is replaced on the car
and to be able to figure out the rental cost quickly and add it to the
time and material costs in repairing the customer's battery.

The Record Card shown in Fig. 183 does not help you locate any
particular rental battery. For instance, suppose that rental battery
No. 896 is out and you wish to know who is using it. You may, of
course, look over the "Battery Tags" which are tied to the batteries
which are being repaired in the shop, or you may examine the file
containing the record cards, but this would take too much time. But if
you refer to the rental file you can determine immediately where
rental battery No. 896 is, since the cards in this file should be
arranged numerically.

The rack on which rental batteries are placed should have a tag
bearing the same number as the rental battery tacked to the shelf
below the place provided for the battery. Each rental battery should
always be placed in the same place on the shelf
