14-24 ELECTRICAL SYSTEM
Battery
3) When you do not use the watercraft for months:
Give a refresh charge before you store the watercraft and store it with the negative lead re-
moved. Give a refresh charge once a month during storage.
4) Battery life:
If the battery will not start the engine even after several refresh charges, the battery has ex-
ceeded its useful life. Replace it (Provided, however, the watercraft’s starting system has no
problem).
WARNING
Keep the battery away from sparks and open flames during charging, since the battery
gives off an explosive gas mixture of hydrogen and oxygen. When using a battery charger,
connect the battery to the charger before turning on the charger.
This procedure prevents sparks at the battery terminals which could ignite any battery
gases.
No fire should be drawn near the battery, or no terminals should have the tightening loos-
ened.
The electrolyte contains sulfuric acid. Be careful not to have it touch your skin or eyes. If
touched, wash it off with liberal amount of water. Get medial attention if severe.
Interchange
A sealed battery can fully display its performance only when combined with a proper watercraft
electric system. Therefore, replace a sealed battery only on watercraft which was originally equipped
with a sealed battery.
Be careful, if a sealed battery is installed on watercraft which had an ordinary battery as original
equipment, the sealed battery’s life will be shortened.
