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).
