Maintenance Fundamentals
# Charging
If you use electrical accessories that drain the
battery or you do not ride frequently, we
recommend that you charge the battery every
30 days using a charger designed specifically for
your Honda, which can be purchased from your
dealer. Read the information that came with
your battery charger and follow the instructions
on the battery. Avoid using an automobile-type
battery charger, as these can overheat a
motorcycle battery and cause permanent
damage.
Make sure the electrical system is off before
charging the battery.
NOTICE
Improper charging can damage the battery. If
you can't charge the battery or it appears unable
to hold a charge, contact your dealer.
