5-4 BATTERY
In fitting the battery to the motorcycle, connect the breather tube to the battery vent.

FILLING ELECTROLYTE
Remove short sealed cap before filling electrolyte. Fill battery with electrolyte(dilute sulfuric cid)
solution with acid concentration of 35.0% by weight, having a specific grvity of 1.28 at 20
℃
up to
indicated MAX.LEVEL. Filling electrolyte should be always cooled below 30
℃
before filling into
battery. Leave battery standing for half an hour after filling. Add additional electrolyte if necessary.
Charge battery with current as desvribed in the table shown below.

CHARGING TIME
The charging time for a new battery is determined by the
number of months that have elapsed since the date of
manufacture.
CONFIRMATION FOR DATE MANUFACTURE
Date of manufacture is indicated by a three-part number

as follows , each indicating month, date and year.
Near the end of charging period, adjust the specific gravity
of electrolyte to value specified. After charging, adjust the
electrolyte level to the MAX.LEVEL with distilled water.

SERVINCE
Visually inspect the surface of the battery container. If any
signs of cracking or electrolyte leakage from the sides of the
bayttery with a new one.
If the battery terminals are found to be coated with rust or
an acidic white powdery substance, then this can be cleaned
away with sandpaper.
Check the electrolyte level and add distilled water, as
necessary, to raise the electrolyte to each cell’s upper level.
Check the battery for proper charge be taking an electrolyte
S.G. reading. If the reading is 1.22 or less, as corrected to 20
℃
,
it means that the battery is still in a run-down condition and
needs recharging.
RECHARGING OPERATION BASED ON S.G. READING
To read the S.G. on the hydrometer, bring the electrolyte in the
hydrometer to eye level and read the graduations on the float
scale bordering on the meniscus (curved-up portion of electrolyte
surface), as shown in figure.
Check the reading (as correct to 20
℃
) with chart to determine the
recharging time in hours by constant-current charging at a charging
