Voltmeter Test
Skandic WT/SWT/SUV 550/SUV 600
The sealed and maintenance free battery has to
be tested with a voltmeter.
Battery testing requires a voltmeter that can mea-
sure DC voltage. Connect a voltmeter parallel to
the circuit being tested, observing polarity; other-
wise, wrong voltmeter reading will appear.
There are two types of battery tests: unload and
load.
An unload test is made on a battery without dis-
charging current. It is the simplest and most com-
monly used method.
An load test is more accurate.

Unload Test
Skandic WT/SWT/SUV 550/SUV 600
Check charge condition by using voltmeter. Volt-
meter readings appear instantly to show the state
of charge.
WARNING
Connect the positive lead to the battery's pos-
itive terminal, and the negative lead to the
negative terminal.

Load Test
All Models
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

Skandic LT E
Disconnect and remove battery from the vehicle.
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 us-
ing a wire brush. Apply a light coat of dielectric
grease (P/N 293 550 004) or petroleum jelly on ter-
minals.
