CHECKING AND CHARGING THE BATTERY
5. Charge:
S battery
(refer to the appropriate charging method il-
lustration)
WARNING
Do not quick charge a battery.
CAUTION:
S Never remove the MF battery sealing caps.
S Do not use a high-rate battery charger
since it forces a high-amperage current
into the battery quickly and can cause bat-
tery overheating and battery plate damage.
S If it is impossible to regulate the charging
current on the battery charger, be careful
not to overcharge the battery.
S When charging a battery, be sure to remove
it from the motorcycle. (if charging has to
be done with the battery mounted on the
motorcycle, disconnect the negative bat-
tery lead from the battery terminal.)
S To reduce the chance of sparks, do not
plug in the battery charger until the battery
charger leads are connected to the battery.
S Before removing the battery charger lead
clips from the battery terminals, be sure to
turn off the battery charger.
S Make sure the battery charger lead clips
are in full contact with the battery terminal
and that they are not shorted. A corroded
battery charger lead clip may generate heat
in the contact area and a weak clip spring
may cause sparks.
S If the battery becomes hot to the touch at
any time during the charging process, dis-
connect the battery charger and let the bat-
tery cool before reconnecting it. Hot batter-
ies can explode!
S As shown in the following illustration, the
open-circuit voltage of an MF battery stabi-
lizes about 30 minutes after charging has
been completed. Therefore, wait 30 min-
utes after charging is completed before
measuring the open-circuit voltage.
