d be given a number which should preferably be painted in
large white figures on the end or side of each case. The number may
also be stamped on a lead tag tied to the handle at the negative end.

A service station which sells a certain make of battery should not use
cases of some other make if the name of the other make appears on the
case. Such names may give a wrong impression to the customer, which
will not be fair either to the service station or to the manufacturer
whose name appears on the case. If the service station sells, another
make of battery, the customer may get the impression that the service
station man does not have enough confidence in the make which he
sells, and must use some other make for his rentals. If the rental
battery does not give good service, the customer will get the
impression that the manufacturer whose name appears on the case does
not turn out good batteries, when as a matter of fact, the plates,
covers, jars, and other parts used in the rental battery may not have
been made by this manufacturer. Some battery men would, perhaps,
consider the failure of a rental battery as an opportunity to "knock"
the manufacturer whose name appears on the case. Such an action may
have the desired effect on a very few customers, but the great
majority of men have no use for any one who "knocks" a competitor's
products.

Keeping a Record of Rental Batteries. A careful record should be kept
of all rental batteries. The more carefully such a record is kept, the
less confusion there will be in knowing just where every rental
battery is. A special rack for rental batteries, such as those shown
in Figures 88 and 89 should be provided, and all rental batteries
which are in the shop should be kept there, except when they are on
charge or are being overhauled. Have them fully charged and ready to
go out immediately, without keeping a customer waiting around, when he
is in a hurry to go somewhere else.

General Rental Policy. No service station should make a practice of
installing rental batteries on any car unless the owner leaves his own
battery to be repaired or recharged. The purpose of having a stock of
rental batteries is to enable customers to have the use of their cars
while their own batteries are being repaired by the battery man who
furnishes the rental battery and not to furnish batteries to car
owners who may be taking their batteries to some other station to be
repaired. It is, of course, a goo
