SERVICE LIFE
Lead oxide is applied to the pole plates of the
battery which will come off gradually during the
service. When the bottom of the battery case
becomes full of the sediment, the battery cannot
be used any more. If the battery is not charged for
a long time, lead sulfate is generated on the surface
of the pole plates and will deteriorate the per-
formance (sulfation). Replace the battery with new
one in such a case.

Charging time (hour)
When a battery is left for a long term without
using, it is apt to subject to sulfation. When the
motorcycle is not used for more than 1 month
(especially during the winter season), recharge the
battery once a month at least.
WARNING:
*
Before charging a battery, remove the seal
cap from each cell.
*
Keep fire and sparks away from a battery
being charged.
*
When removing a battery from the mo-
torcycle, be sure to remove the (-) termi·
nal first.
