Battery and Battery Charge
r
▪
Never allow the electrolyte level to fall below the top of the
plates (A). If the plates are exposed, add only enough
distilled water to cover the plates before charging.
▪
Do not overfill batteries. Do not fill the water level up into
the well of the filler tube of the cell. Electrolyte expands and
can overflow during charging (B). Water added to replace
the spillage dilutes the electrolyte and reduces its specific
gravity. Cells with lower specific gravity have lower
charging capacity.
▪
Make sure the electrolyte covers the plates before charging
(C). Fill cells to the markers only after batteries are
charged.
SINGLE POINT WATERING SYSTEM
NOTICE: The following information does not apply to
sealed batteries.
These vehicles may have a Single Point Watering System
(Figure 9-2) used for adding water to the battery pack. It
consists of a fill tube, one end having a filter screen, the other
having a female coupler and a rubber squeeze bulb.
NOTICE: To avoid overfilling of the Single Point
Watering System do not operate this system on brand
new batteries. New batteries should be in service 1 to 2
weeks with heavy use or 3 to 4 weeks with light use.
System is to be used only after fully charging the
batteries and batteries are warm.
When using this system, check the battery pack water level
weekly by:
▪
Inserting the fill tube filter end in a distilled water supply.
▪
Attaching the female coupler to the battery pack male
coupler.
▪
Squeeze the rubber ball until firm which indicates that filling
is complete. Immediately disconnect the couplers by
depressing the push button on the female coupler. If the
water supply is left connected after the filling process is
finished it could lead to an overfill.
Some US Batteries features SpeedCap™ battery cell caps. To
open SpeedCap™ locate the two tabs on either side of the
center cell of the battery. Move these tabs in the directions
shown in Figure 9-3.

NOTICE
: Do not use SpeedCaps™ as handles to lift or
move battery.
