AK 550
• When a battery is overcharged, some symptoms can be found. If there is a
short circuit inside the battery, no voltage is produced on the battery terminals. If
the rectifier won't operate, the voltage will become too high and shorten the
battery service life.
• If a battery is not used for a long time, it will discharge by itself and should be
recharged every 3 months.
• A new battery filled with electrolyte will generate voltage within a certain time
and it should be recharged when the capacity is insufficient. Recharging a new
battery will prolong its service life.
• Inspect the charging system according to the sequence specified in the
Troubleshooting.
• Do not disconnect and soon reconnect the power of any electrical equipment
because the electronic parts in the regulator/rectifier will be damaged. Turn off
the ignition switch before operation.
• It is not necessary to check the MF battery electrolyte or fill with distilled water.
• Check the load of the whole charging system.
• Do not quick charge the battery. Quick charging should only be done in an
emergency.
• Remove the battery from the motorcycle for charging.
• When replacing the battery, do not use a traditional battery.
• When charging, check the voltage with an electric tester.
