(1) charger
Be sure to read the information that came with
your battery charger and follow the instructions
on the battery. Improper charging may damage
the battery.
We recommend using a charger (1) designed
specifically for your Honda, which can be
purchased from your dealer. These units can be
left connected for long periods without risking
damage to the battery. However, do not
intentionally leave the charger connected
longer than the time period recommended in
the charger's instructions.
Avoid using an automotive-type battery
charger. An automotive charger can overheat a
motorcycle battery and cause permanent
damage.
