Battery - Rotax 125 MAX DD2 evo Installation Instructions And Operators Manual

See Fig.
The 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 hun-
dred times and operated over a period of approximately five hours. With the battery volt-
age decreasing to approximately 11 V the point will be reached when the battery voltage
is too low to generate a spark for ignition.
The lifespan of the battery will be drastically reduced by exhausting the battery
NOTE
It is recommended to always carry a charged spare battery. The installed battery
should be replaced with a fully charged battery before it is completely exhausted.
NOTE
If the spark plug is removed, to check if the battery still generates a spark, consid-
er 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, result-
ing in battery voltage adequate to generate a spark. If the spark plug is fitted
again, it may happen that the engine does not start.
NOTE
To charge a battery, the delivered battery charging unit specified by ROTAX®
should be utilized (battery charger part no. 265148). When using the lithium bat-
tery available as spare part, the battery charger Optimate Lithium (part no.
581325) is mandatory.
NOTE
To be able to use the battery charger in your home country, please contact your
nearest authorized ROTAX® distributor or one of their ROTAX® Service Centers
to receive an adapter plug or adapter cable, respectively.
NOTE
This battery charger will switch over automatically to maintenance charge as soon
as the target voltage is reached. Therefore overcharging with the result of ruining
the battery will be impossible.
