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 by taking an electrolyte
S.G. reading. If the reading is 1.22 or less, as corrected to
20 C, it means that the battery is still in a run-down condition
and needs recharging.

CAUTION
BASED ON S.G. READING
RECHARGING OPERATION
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 electroylte) as shown in figure.
Check the reading (as corrected to 20 C) with chart to
determine the recharging time in hours by constant-current
charging at a charging rate of 0.7A.
Be careful not to permit the electrolyte temperature to
exceed 45 C, at any time during the recharging operation.
Interrupt the operation, as necessary, to let the electrolyte
cool down. Recharge the battery to the specification.

Constant-voltage charging, otherwise called “quick”
charging, is not recommendable for it could shorten the
life of the battery.
Before charging a battery, remove the seal cap from each
cell.
Keep fire and sparks away from a battery being charged.
When removing a battery from the motorcycle, be sure to
remove the terminal first.
