DESCRIPTION
There are two different batteries available on this
model. Vehicles equipped with a diesel engine utilize
a spiral wound plate designed battery with recombi-
nation technology. This is a maintenance-free battery
that is capable of delivering more power than a con-
ventional battery. This additional power is required
by a diesel engine during cold cranking. Vehicles
equipped with a gasoline engine utilize a conven-
tional battery. Refer to the following information for
detailed differences and descriptions of these two bat-
teries.
SPIRAL PLATE BATTERY - DIESEL ENGINE
Spiral plate technology takes the elements of tradi-
tional batteries - lead and sulfuric acid - to the next
level. By tightly winding layers of spiral grids and
acid-permeated vitreous separators into cells, the
manufacturer has developed a battery with more
power and service life than conventional batteries the
same size. The spiral plate battery is completely, per-
manently sealed. Through gas recombination, hydro-
gen and oxygen within the battery are captured
during normal charging and reunited to form the
water within the electrolyte, eliminating the need to
add distilled water. Therefore, these batteries have
non-removable battery vent caps (Fig. 1). Watercan-
notbe added to this battery.The acid inside an spiral plate battery is bound
within the vitreous separators, ending the threat of
acid leaks. This feature allows the battery to be
installed in any position anywhere in the vehicle.

Spiral plate technology is the process by which the
plates holding the active material in the battery are
wound tightly in coils instead of hanging flat, like
conventional batteries. This design has a lower inter-
nal resistance and also increases the active material
surface area.
WARNING: NEVER EXCEED 14.4 VOLTS WHEN
CHARGING A SPIRAL PLATE BATTERY. PERSONAL
INJURY AND/OR BATTERY DAMAGE MAY RESULT.
Due to the maintanance-free design, distilled water
cannot be added to this battery. Therefore, if more
than 14.4 volts are used during the spiral plate bat-
tery charging process, water vapor can be exhausted
through the pressure-sensitive battery vents and lost
for good. This can permanently damage the spiral
plate battery. Never exceed 14.4 volts when charging
a spiral plate battery. Personal injury and/or battery
damage may result.
CONVENTIONAL BATTERY - GASOLINE ENGINE
Low-maintenance conventional batteries are used
on vehicles equipped with a gasoline engine, these
batteries have removable battery cell caps (Fig. 2).
Watercanbe added to this battery. Under normal
service, the composition of this battery reduces gas-
sing and water loss at normal charge rates. Howeverthese batteries may require additional distilled water
after years of service.
Conventional batteries are made up of six individ-
ual cells that are connected in series. Each cell con-
tains positive charged plate groups made of lead
oxide, and negatively charged plate groups made of
sponge lead. The plates are submerged in a sulfuric
acid and water solution called electrolyte.
Both batteries are used to store electrical energy
potential in a chemical form. When an electrical load
is applied to the battery terminals, an electrochemi-
cal reaction occurs within the battery. This reaction
causes the battery to discharge electrical current.
Refer to the RS service information for additional
Battery System information.
STANDARD PROCEDURE - CHECKING BATTERY
ELECTROLYTE LEVEL
The following procedure can be used to check the
electrolyte level in a lead-acid battery.
(1) Unscrew and remove the battery cell caps with
a flat-bladed screw driver (Fig. 3).
WARNING: NEVER PUT YOUR FACE NEAR A GAS-
SING, HOT OR SWELLED BATTERY. SERIOUS PER-
SONAL INJURY MAY RESULT.
(2) Wearing safety glasses, look through the bat-
tery cell cap holes to determine the level of the elec-
trolyte in the battery. The electrolyte should be above
the hooks inside the battery cells (Fig. 4).

STANDARD PROCEDURE - SPIRAL PLATE
BATTERY CHARGING
Battery charging is the means by which the bat-
tery can be restored to its full voltage potential. A
battery is fully-charged when:
²Open-circuit voltage of the battery is 12.65 volts
or above.
²Battery passes Load Test multiple times.
WARNING: IF THE BATTERY SHOWS SIGNS OF
FREEZING, LEAKING, LOOSE POSTS OR LOW
ELECTROLYTE LEVEL, DO NOT TEST, ASSIST-
BOOST, OR CHARGE. THE BATTERY MAY ARC
INTERNALLY AND EXPLODE. PERSONAL INJURY
AND/OR VEHICLE DAMAGE MAY RESULT.
CAUTION: Always disconnect and isolate the bat-
tery negative cable before charging a battery. Do
not exceed 14.4 volts while charging a battery.
CAUTION: The battery should not be hot to the
touch. If the battery feels hot to the touch, turn off
the charger and let the battery cool before continu-
ing the charging operation. Damage to the battery
may result.After the battery has been charged to 12.6 volts or
greater, perform a load test to determine the battery
cranking capacity. Refer to Standard Procedures for
the proper battery load test procedures. If the battery
will endure a load test, return the battery to service.
If the battery will not endure a load test, it is faulty
and must be replaced.
Clean and inspect the battery hold downs, tray,
terminals, posts, and top before completing battery
service. Refer to Battery System Cleaning for the
proper battery system cleaning procedures, and Bat-
tery System Inspection for the proper battery system
inspection procedures.
CHARGING A COMPLETELY DISCHARGED
BATTERY ± SPIRAL PLATE BATTERY
The following procedure should be used to recharge
a completely discharged battery. Unless this proce-
dure is properly followed, a good battery may be
needlessly replaced.
(1) Measure the voltage at the battery posts with a
voltmeter, accurate to 1/10 (0.10) volt (Fig. 5). If the
reading is below ten volts, the battery charging cur-
rent will be low. It could take some time before the
battery accepts a current greater than a few milliam-
peres. Such low current may not be detectable on the
ammeters built into many battery chargers.
(2) Disconnect and isolate the battery negative
cable. Connect the battery charger leads. Some bat-
tery chargers are equipped with polarity-sensing cir-
cuitry. This circuitry protects the battery charger and
the battery from being damaged if they are improp-
erly connected. If the battery state-of-charge is too
low for the polarity-sensing circuitry to detect, the
battery charger will not operate. This makes it
appear that the battery will not accept charging cur-
rent. See the instructions provided by the manufac-
turer of the battery charger for details on how to
bypass the polarity-sensing circuitry.

(3) Battery chargers vary in the amount of voltage
and current they provide. The amount of time
required for a battery to accept measurable charging
current at various voltages is shown in the Charge
Rate Table. If the charging current is still not mea-
surable at the end of the charging time, the battery
is faulty and must be replaced. If the charging cur-
rent is measurable during the charging time, the bat-
tery may be good and the charging should be
completed in the normal manner.

Voltage Hours
14.4 volts maximum up to 4 hours
13.0 to 14 volts up to 8 hours
12.9 volts or less up to 16 hours
CHARGING TIME REQUIRED
The time required to charge a battery will vary,
depending upon the following factors:
²Battery Capacity- A completely discharged
heavy-duty battery requires twice the charging time
of a small capacity battery.
²Temperature- A longer time will be needed to
charge a battery at -18É C (0É F) than at 27É C (80É
F). When a fast battery charger is connected to a cold
battery, the current accepted by the battery will be
very low at first. As the battery warms, it will accept
a higher charging current rate (amperage).
²Charger Capacity- A battery charger that
supplies only five amperes will require a longer
charging time. A battery charger that supplies eight
amperes will require a shorter charging time.
²State-Of-Charge- A completely discharged bat-
tery requires more charging time than a partially
discharged battery. Electrolyte is nearly pure water
in a completely discharged battery. At first, the
charging current (amperage) will be low. As the bat-
tery charges, the specific gravity of the electrolyte
will gradually rise.
The Battery Charging Time Table gives an indica-
tion of the time required to charge a typical battery
at room temperature based upon the battery state-of-
charge and the charger capacity.
