Batteries; Cleaning - Yamaha AR240 HO Owner's Manual

Should the Start battery become dis-
charged the Emergency Parallel switch
should be rotated to the On (Green)
position and the engines started. After
starting or when the discharged bat-
tery has recovered, the Emergency
Parallel switch can be returned to the
off position.

BATTERIES

1) When the boat is not to be used for
a month or more, remove the bat-
teries and store them in a cool, dark
place. Clean each battery's casing
and terminals using Yamalube Bat-
tery Cleaner & Protector or a mix-
ture of baking soda and water (one
tbsp. of baking soda to one cup
of water). Apply dielectric grease
or petroleum jelly to the battery
terminals and to all exposed
connectors.
2) If the batteries will be stored for a
longer period, check the specific
gravity of the fluid at least once a
month and recharge each battery if
it gets too low.
Specific gravity: 1.28 at 20°C (68°F)
M
aintenance
For maintenance free (MF) type bat-
teries with sealed cells, check the
terminal voltage monthly. When the
terminal voltage drops to 12.5 VDC
or lower, recharge the battery with an
appropriate charger as recommended
by the battery manufacturer.
Full charge terminal voltage:
12.7~13.0 VDC per battery manufac-
turer's specification.
