– If the charging current is measurable before the
end or at the end of about 10 hours, the battery
is good and charging should be completed in
the normal manner as specified in
Activation
of a new battery .
– It is recommended that any battery recharged
by this procedure be load tested prior to return-
ing it to service.
BATTERY CHARGING
EQUIPMENT
The battery charger should have an adjustable
charging rate. Variable adjustment is preferred,
but a unit which can be adjusted in small incre-
ments is acceptable.
The battery charger must be equipped with an
ammeter capable of accurately measuring current
of less than one ampere.
If the present charger is not adjustable to the
proper current values, a rheostat can be connect-
ed in series with the battery to provide adjust-
ment. 12 Ohm, 50 watt rheostat, such as
OHMITE — 0314 or MALLORY 50K 12P, are avail-
able from electronic parts supply shops and they
are suitable for use with most chargers if the peak
current is to be held below 2 amps.
If you need an accurate ammeter, we recommend
the use of: SHURITE — 5202 (0 to 3 amps) or —
5203 (0 to 5 amps) available from electronic parts
supply shops.

For a service application and a permanent installa-
tion, both ammeter and rheostat can be built into
a small box adjacent to your charger.
Charging 2 or More Batteries at a Time
Connect all positives together and use a charger
with a capacity (rated) equal to: number of battery
to be charged multiply by 2 A.
For example: charging five batteries at a time re-
quires a 10 A rated charger (5

2 A
=
10 A).

INSTALLATION OF BATTERY
Ensure vent tube is properly installed on battery
elbow.
Connect vent tube to vehicle fitting on front
frame.
Route RED positive cable behind retaining strip
and connect it to positive battery terminal. Con-
nect RED wire (coming from ignition switch).
Connect BLACK negative cable LAST.
