Subsection 04 (BATTERY)

CLEANING

Clean the battery, battery casing, vent tube, caps,
cables and battery posts using a solution of baking
soda and water.
CAUTION: Do not allow cleaning solution to en-
ter battery interior since it will destroy the elec-
trolyte.
1. Baking soda
Remove corrosion from battery cable terminals
and battery posts using a firm wire brush.Battery
top should be cleaned by soft brush and any
grease-cutting soap or baking soda solution

INSPECTION

Visually inspect battery casing for cracks or other
possible damage.Discoloration, warping or raised
top, indicates that battery has overheated or been
overcharged. If casting is damaged, replace bat-
tery and thoroughly clean battery tray and close
area with water and baking soda.
WARNING
Should the battery casing be damaged, wear
a suitable pair of non-absorbent gloves when
removing the battery by hand.
Inspect battery posts for security of mounting.
Inspect for cracked or damaged battery caps, re-
place defective caps.
WARNING
Battery caps do not have vent holes. Make
sure that vent tube is not obstructed.

BATTERY CHARGE TESTING

Skandic LT E
Hydrometer Test
1. Specific gravity 1.265
A hydrometer measures the charge of a battery in
terms of specific gravity of the electrolyte. Most
hydrometers give a true reading at 25°C (77°F).
In order to obtain correct readings, adjust the initial
reading by adding .001 to the hydrometer readings
for each 2°C (3°F) above 25°C (77°F) and by sub-
tracting .001 for every 2°C (3°F) below 25°C (77°F).
This chart will be useful to find the correct reading.
