ent cycle, i. e., to discharge it at about the four-hour rate
and then put it on the charging line again at the normal rate until a
condition of full charge is again reached. The objects gained by this
discharge are:

(a) Further development of the plates.

(b) Adjustment or stabilization of the electrolyte.

(c) Checking the assembly by noting the failure of any cell or cells
to act uniformly and satisfactorily during discharge.

The four-hour discharge rate is, of course, like the normal rate of
Initial Charge, dependent upon the size and number of plates per cell
in any particular battery; the number of cells determines the voltage
only and has nothing to do with the battery's charge or discharging
rating. These four-hour discharge rates are as follows:

Plates
per Cell Type of Plate
AHS WHN RHN SHC BHN JFN GM CLN KPN
-------- --- --- --- --- --- --- -- --- ---
3 3
5 5 5 5.5 6.5
7 7.5 7.5 8 10 7.5 13.5
9 10 10 11 13 18
11 12.5 12.5 14 16 19 12.5 22.5
13 15 15 16.5 19.5 22.5 15 27 27
15 17.5 17.5 19 23 26 17.5 31.5
17 22 26
19 22.5 22.5 25 29 22.5

Immediately at the end of the four-hour discharge, put the battery on
the line and charge it at the normal rate prescribed in the Initial
Charge rate table until a state of complete charge, as noted by cell
voltage and gravity is reached. This charging time should be about
sixteen hours.

Any adjustments of electrolyte found necessary at the end of this
charging period in the same manner prescribed in paragraph No. 5, for
such adjustments made just before the completion of the initial
fifty-two hour charge.

(TRANSCRIBER'S NOTE: No item number 7. in original publication.)

8. At the end of the fifty-two hour charge, or, if the Development
discharge has been given, at the end of the Development Cycle Charge,
replace the vent plugs, wash all exterior surfaces with clean water
and dry quickly. The battery is then ready for service.

INSTALLING A BATTERY ON A CAR

A battery must be installed carefully on the car if it is to have any
chance to give good service. Careless installation of a battery which
is in good working or
