Kawasaki J300 - Owner's Manual > Battery
The battery installed in this motorcycle is a sealed type, so it is not necessary to check the battery electrolyte level or add distilled water.
Never remove the sealing strip, or the battery can be damaged.
Do not install a conventional battery in this motorcycle, or the electrical system cannot work properly.
It is the owner's responsibility to keep the battery fully charged. Failure to do so can lead to battery failure and leave you stranded.
If you are riding your vehicle infrequently, inspect the battery voltage weekly using a voltmeter. If it drops below 12.8 volts, the battery should be charged using an appropriate charger (check with your Kawasaki dealer). If you will not be using the motorcycle for longer than two weeks, the battery should be charged using an appropriate charger. Do not use an automotive-type quick charger that may overcharge the battery and damage it.
- Leaving the battery connected causes the electrical components (clock etc.) to make the battery discharged, resulting the over discharge of the battery. In this case, the repair or replacement of the battery is not included in the warranty. If you do not drive for four weeks or more, disconnect the battery from the vehicle.
Kawasaki-recommended chargers are:
Battery Mate 150-9
If the above chargers are not available, use equivalent one.
For more details, ask your Kawasaki dealer.
- Charge the battery following the instructions of your battery charger.
- The charger will keep the battery fully charged until you are ready to reinstall the battery in the motorcycle (see Battery Installation).

Fuses are arranged in the fuse box located battery case. If a fuse fails during operation, inspect the electrical system to determine the cause, and then replace it with a new fuse of proper amperage.
If the fuse fails repeatedly, there is something wrong with the electrical system. Have the motorcycle checked by an authorized Kawasaki dealer.

Substituting fuses can cause wiring to overheat, catch fire and/or fail. Do not use any substitute for the standard fuse. Replace the blown fuse with a new one of the correct capacity, as specified on the fuse.
