1. Specific gravity 1.265
In order to obtain correct readings, adjust the initial
reading by
adding
.004 points to the hydrometer
readings for each 5.5°C (10°F)
above
21°C (70°F)
and by
subtracting
.004 point for every 5.5°C
(10°F)
below
21°C (70°F).
This chart will be useful to find the correct reading.
Load Test
This is the best test of battery condition under a
starting load. Use a load testing device that has an
adjustable load.
Apply a load of 3 times the ampere-hour rating of
the battery. At 14 seconds into the test, check bat-
tery voltage; if battery is in good condition, it will
have at least 10.5 Vdc.
Battery Storage
Disconnect and remove battery from watercraft
as explained in
Removal
.
Check electrolyte level in each cell, add distilled
water up to upper level line.
CAUTION:
Do not overfill.
The battery must always be stored in fully charged
condition. If required, charge until specific gravity
of 1.265 is obtained.
CAUTION:
Battery electrolyte temperature must
not exceed 50°C (122°F). The casing should not
feel hot.
Clean battery terminals and cable connections using
a wire brush. Apply a light coat of dielectric grease
on terminals.
Clean battery casing and caps using a solution of
baking soda and water.
CAUTION:
Do not allow cleaning solution to en-
ter battery.
Rinse battery with clear water and dry well using
a clean cloth.
Store battery on a wooden shelf in a cool dry place.
Such conditions reduce self-discharging and keep
fluid evaporation to a minimum. Keep battery
away from dew, high moisture and direct sunlight.
During the storage period, recheck electrolyte lev-
el and specific gravity readings at least every
month. If necessary, keep the battery at its upper
level line and near full charge as possible (trickle
charge).
Activation of a New Battery
A new battery is factory fresh dry charged. For
storage purposes, it is fitted with a temporary seal-
ing tube.
CAUTION:
Do not remove the sealing tube or
loosen battery caps unless activation is desired.
NOTE:
In case of accidental premature removal
of caps or sealing tube, battery should be given a
full charge.
Perform the following operations anytime a new
battery is to be installed.

Never charge or boost battery while installed in
watercraft.
