fi lling. Fill to the UPPER LEVEL as indicated on the battery.
NOTE: Never fi ll/activate a battery installed in a vehicle as
electrolyte spillage can cause damage.
5. Fill each battery cell slowly and carefully to the highest level
line.
6. Let the battery stand for at least 30 minutes after fi lling.
Move or gently tap the battery so that any air bubbles
between the plates will be expelled. If the acid level has
fallen, refi ll with acid to upper level.
7. Filling a Conventional battery with electrolyte will bring it
to
75-80% of a full charge. A battery must be charged
to
100% before putting it into service. To fi nd
recommended charging current requirements in amps for
a specifi c battery, divide battery ampere-hour capacity
rating by
10. For example a 14 AH battery should be charged
at
1.4 amps (14 AH ÷ 10 = 1.4 amps). The specifi c gravity of
the electrolyte should rise to at least
1.260 on 12N series
batteries. On all High Performance batteries (YB Series) a
minimal reading of
1.270 should be observed.
During initial charging check to see if the electrolyte level
has fallen, and if so, fi ll with acid to the UPPER LEVEL. After
adding acid, charge for another hour at same rate as above
to mix the water and acid together. Note: This is the last time
electrolyte should be added to the battery. If the level is low
during use, distilled water should be added as required.
8. When charging is complete, replace fi ller cap plugs and
tighten by hand—do not use a screwdriver or pliers. Wash
off spilled acid with a water and baking soda solution,
paying particular attention that any acid is washed off the
terminals. Dry the battery case and install the battery.
POINTS TO REMEMBER
■ Newly activated AGM and Conventional batteries require an
initial charge before being placed into service
■ Yuasa Smart Battery Chargers use constant current and
pulse technology and can activate, charge and maintain all
Yuasa batteries
■ High-rate, automotive types of chargers can cause damage
to powersports batteries
■ High performance batteries (designated by an “H” in the
part number) must stand
1 to 2 hours after initial charging
■ Never remove the strip of caps on an AGM battery to add
water or electrolyte during its service life
■ Before activation of Conventional batteries remove the red
sealing cap from the vent elbow and discard it
