Rechrging Operation Based On S.g. Reading; Service Life - Suzuki Katana 1100 Service Manual

ELECTRICAL SYSTEM 6-24
RECHARGING OPERATION BASED ON S.G.
READING
To read the S.G. on the hydrometer, bring the electrolyte in the
hydrometer to eye level and read the graduation on the float
scale bordering on the meniscus (curved-up portion of electro ­
lyte surface), as shown in figure.
09900-28403: Hydrometer
Check the reading (as corrected to 20"C) with chart to
determine the recharging time in hour by constant-current
charging at a charging rate of 1.4 amperes (which is tenth of
the capacity of the present battery).
Be careful not to permit the electrolyte temperature to exceed
45°C (113'F), at any time, during the recharging operation.
Interrupt the operation, as necessary, to let the electrolyte cool
down. Recharge the battery to the specification.
Electrolyte specific gravity: 1.28 at 20
c
C (68°F)
CAUTION:
Constant-voltage charging, otherwise called "quick" charg ­
ing, is not recommendable for it could shorten the life of the
battery.
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 performance (sulfation). Replace
the battery with new one in such a case.
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 motorcycle, be sure
to remove the
8
terminal first.
