– If the charging current is not up to a measurable
amount at the end of about 10 hours, the bat-
tery should be replaced.
– 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 available from
electronic parts supply shops and they are suit-
able for use with most chargers if the peak cur-
rent is to be held below 2 A.
If you need an accurate ammeter, we recommend
the use of: SHURITE — 5202 (0 to 3 A) or — 5203
(0 to 5 A) 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 batter-
ies to be charged multiply by 2 A.
For example: Charging 5 batteries at a time re-
quires a 10 A rated charger (5
×
2 A
=
10 A).
TYPICAL
1. Two batteries = 4 A
INSTALLATION OF BATTERY
Position battery onto battery support on vehicle.
NOTE:
To ease battery insertion, use soap with
water.
Install vent tube on battery.
NOTE:
Ensure that vent tube is not kinked or
blocked. Cut vent tube if necessary.
Red Positive Cable and Wire
Move RED positive cable and wire from right side
of engine compartment to battery positive post,
as shown in the next photo.
