SERVICING
Visually inspect the surface of the battery container. If any signs
of cracking or electrolyte leakage from the sides of the battery
have occurred, replace the battery with a new one. If the battery
terminals are found to be coated with rust or an acidic white
powdery substance, clean the battery terminals with sandpaper.

RECHARGING OPERATION

• Using the multi circuit tester, check the battery voltage. If the
voltage reading is the 12.0 V (DC) and less, recharge the bat-
tery with a battery charger.
• Remove the battery from the motorcycle.
Do not remove the caps on the battery top while
recharging.
Recharging time: 0.9 A for 5 to 10 hours or 4 A for 1 hour
Be careful not to permit the charging current to
exceed 5 A at any time.
• After recharging, wait for 30 minutes and more and check the
battery voltage with a multi circuit tester.
• If the battery voltage is the 12.5 V and less, recharge the bat-
tery again.
• If battery voltage is still 12.5 V and less, after recharging,
replace the battery with a new one.
• When the motorcycle is not used for a long period, check the
battery every 1 month to prevent the battery discharge.
