These general guidelines apply to many com-
monly used battery types (but not, for exam-
ple, to maintenance-free batteries). Consult
the battery manufacturer's instructions before
performing battery maintenance.
Check the level of the battery fluid and see if
the terminals are tight. Add distilled water if
the fluid level is low.
NOTICE
Be careful not to place the battery on its
●
side.
Remove the battery from the boat before
●
adding distilled water or recharging.
Before replenishing the battery fluid and re-
charging the battery, remove the battery from
the boat. After completing the procedures, in-
stall the battery. (See page 121 for battery re-
moval and installation procedures.)
Replenishing the battery fluid
A poorly maintained battery will deteriorate
quickly. The battery fluid should be checked
before every outing.
Fill to the manufacturer's recommended level
when necessary. Top up only with distilled
water (or pure de-ionized water) suitable to
use in batteries. NOTICE: Normal tap water
contains minerals which are harmful to a
battery; therefore, refill only with distilled
water.
Recharging
WARNING
When charging the battery, keep it well
●
away from sparks and open flames, as it
gives off explosive gases.
When using a battery charger, connect
●
the battery to the charger before you
turn on the charger. This will prevent
sparking at the terminals that could ig-
nite battery gases.
(1) Remove the caps from the cells. Add dis-
tilled water if necessary to top up the
electrolyte to the proper level.
(2) Follow the battery manufacturer's instruc-
tions for charging.
