DANGER
To prevent possible electric shocks or
sparking, the battery master switches should
be in the "Off" position before disconnecting
cables from the batteries (see paragraph "3.8
Battery safety switches").
2. Remove the supports, and unscrew terminal
nuts of each defective battery.
3. Remove battery cables from the batteries.
4. Remove batteries.
5. Installation is the reverse of removal.
NOTE
When the battery cables have been removed
from the batteries, wrap the battery terminals
and cable ends with electric tape to prevent
accidental grounding. The ground cables
should always be disconnected first and
replaced last.
NOTE
In replacing batteries, only batteries of the
same specification should be used. Refer to
“Specifications” at the end of this section for
further details.
CAUTION
Ensure that connections are not reversed
when reinstalling batteries, since damage to
electrical system components will result.
NOTE
When reinstalling batteries, battery
connections must be tightened to 13-15 lbf-ft
(18-20) Nm). A torque wrench is required to
ensure an accurate tightening torque.
DANGER
To prevent possible electric shock or sparking,
the battery master switch must be set to the
“Off” position before tightening an electrical
connection.
NOTE
A protective silicone free, coating should be
applied on all terminals that have been
disconnected. We recommend the use of
Cortec VCI-238 (Prévost #682460) on all
electrical connections.
3.4 BATTERY RATING
Each of the 12 volt batteries used on the vehicle
has the following rating:
• Reserve capacity: 195 minutes
• Cold cranking (amps): 950 @ 0
o
F (-18
o
C)
• Cold cranking (amps): 745 @ -20
o
F (-29
o
C)
• Weight (filled): 59 lb (26,7 kg)
The reserve capacity is defined as the number
of minutes a new, fully charged battery at 80
o
F
(26,6
o
C) can be discharged at 25 amperes and
maintain a minimum of 1.75 volts per cell (10.5
volts total for one 12 volts battery). This rating
can be used as a basis for determining how long
a vehicle might run after an alternator failure.
The cold cranking rating is defined as the
minimum discharge current a battery will deliver
in amperes for 30 seconds at 0
o
F (-18
o
C) while
maintaining a minimum of 1.2 volts per cell (7.2
volts total for one 12 volts battery). This rating
can be used as a basis for comparing starting
performance.
3.5 BATTERY TESTING
The maintenance-free battery has a strong
ability to withstand the damaging effects of
overcharge. The test indicator in the cover is
used only to determine if the battery can be
tested in case of a cranking problem.
The test indicator in the battery cover is to be
used with accepted diagnostic procedures only.
It must not be used to determine if the battery is
good or bad, charged or discharged. The test
indicator is a built-in hydrometer in one cell that
provides visual information for battery testing
(Fig. 12).
It is important when observing the test indicator,
that the battery be relatively level and has a
clean indicator top to see the correct indication.
Some lighting may be required in poorly lit
areas. Under normal operation, two indications
can be observed.
