The maintenance-free battery is identified
by the absence of vent plugs on the cover. The
side-mounted positive and negative terminals
are tightly sealed to retard possible leakage .
Except for the small vent hole located on the
side, the battery is completely sealed.
The
vent hole should be free from obstruction
because it allows gases produced in the battery
to escape . At normal charging voltages, the
amount of these gases is extremely small, due
to the special chemical composition in the
battery grid design. Water never needs to be
added to the maintenance-free battery .
CHARGE-TEST INDICATOR
A charge or test indicator in the battery
cover provides a visual inspection area for
testing purposes only. Correct use of this
feature is important . Refer to "Testing Main-
tenance-Free Batteries" below . Refer also to
figure 1 in this section.

TESTING MAINTENANCE-FREE
BATTERIES
6Y-1
STEP 1 - VISUAL INSPECTION
Check for obvious damage, such as cracked
or broken case or cover that could permit loss
of electrolyte . If obvious physical damage is
noted, replace battery . Determine cause of
damage and correct as necessary .
STEP 2 - CHARGE OR TEST INDICATOR
The charge or test indicator, built into the
top cover, provides a visual inspection area for
battery testing only . This test indicator is to
be
used
only
with
accepted
diagnostic
procedures .
It is not to be used by itself to
determine if the battery is good or bad, or
charged or discharged . The indicator includes a
plastic rod that extends into the electrolyte.
At the bottom of the rod, a green plastic ball
is suspended in a cage .
When the electrolyte
specific gravity is about 1 .225 or above, the
green ball floats against the end of the rod and
becomes visible so that the indicator appears
