3.2. Battery and battery charging unit
Power for the ignition unit and electric starter is only supplied from the battery. With a fully charged
battery of 12 V and 6,5 Ah the engine can be started approximately one hundred times and
operated over a period of approximately five hours. With the battery voltage decreasing to
approximately 11 V the point will be reached when the battery voltage is too low to generate a
spark for ignition.
Attention: The life span of the battery will be drastically reduced by exhausting the battery
completely. Therefore it is recommended to fully re-charge the battery before and
after any operation of the kart.
Note:
It is recommended to always carry a charged spare battery. The installed battery
should be replaced by a fully charged battery before it is completely exhausted.
Note:
If the spark plug will be removed, to check if the battery still generates a spark,
consider the following: with the spark plug removed it is easier for the electric starter
to crank the engine, which reduces current absorption of the electric starter resulting
in battery voltage adequate to generate a spark. But if the spark plug is fitted again it
may happen that the engine won't start.
Note:
To charge a battery, the battery charging unit specified by Rotax and available as an
accessory should be utilized (charging unit, part no. 265 148).
Note:
To be able to use the battery charger in your home country pls. contact your nearest
authorized ROTAX distributor or one of his Rotax service center to receive an
adapter plug resp. an adapter cable.
Note:
This battery charger includes the feature that when the target voltage is reached it
will switch over automatically to maintenance charge. Therefore overcharging with
the result of ruining the battery will be impossible.
Attention: Use of any other battery charger can impair
the battery life or may ruin the battery.
When charging the battery take note of the following:
Connect battery charger to the charging
connector.
Attention: The battery charger is not equipped with a
protection
Incorrect polarity of connection would result
in the damage of the battery charger.
Connect the battery charging unit on 110-
230V, 50-60Hz power supply. During the
charging procedure the charge indicating
lamp will light up red.
