Clean the battery casing using fresh water.
If the battery terminals are dirty or cor- roded, clean the mating surfaces on the terminals for the battery cables using the wiring brush or equivalents.
Recharge the battery, and then store it in a cool and dark place.
Apply the Yamaha marine grease/Yamaha grease A to the battery terminals.
Recharge the battery periodically at least 2 months because a battery will discharge electricity by itself while storing.
CAUTION:
The battery may be impossible to use again if you store it for a longer time without recharging. Recharge the battery periodically.
NOTE:
The battery condition can be found by checking the specific gravity of the electro- lyte. However, you can also know the battery condition roughly by measuring the voltage at both battery terminals. Recharge the battery if the voltage is 12 volts or less.
Specific gravity of electrolyte (for reference):
1.28 at 20 °C (68 °F)
Yamaha recommend checking the specific gravity of the electrolyte and charging battery by a Yamaha dealer or a battery dealer. If you maintain the battery yourself, read carefully the instructions for the tool and machine before maintenance.
