Chapter 4: Battery Test
Additional Test Requirements and Messages
For a more decisive result the tester may ask for additional
information or probe deeper into the battery's condition. The
following messages and instructions may appear before the
analyzer displays the results of your test.
System Noise
To perform a correct measurement the tester requires the
vessel to be in rest. After the boat has sailed, some vessel
specific systems might still be active in the background.
The tester will detect this and displays the message
SYSTEM NOISE. When this message appears switch off all
consumers(radio, airconditioning) and remove the key from
the ignition. As soon as there is no more activity in the vessel,
the tester will continue testing and display the test result.
Unstable Battery Detected
A battery that is weak or that has just been charged may retain
enough electrical activity to be detected by the analyzer
and will adversely affect the test results. A fully charged
battery should stabilize quickly, after which the analyzer
will automatically retest. Weak batteries should be charged
and retested. If the battery is fully charged, check the clamp
connections.
Surface Charge
The battery can hold a surface charge if the engine has been
running or after the battery has been charged. The tester may
prompt you to remove the surface charge before it displays a
test result.
1.
Follow the instructions indicating when to turn the head-
lights on and off (IN-VESSEL)
2.
The tester will resume testing after it detects that the sur-
face charge is removed.
Deep Scan Test
In some cases the tester may need to further analyze the
battery to determine whether the battery should be replaced
or it has a significant chance to be recovered. It will then
conduct a Deep Scan Test of the battery for a few seconds.
This test will typically be performed on batteries that are in a
low state of charge.

Recommended Action
Return the battery to service.
Fully charge the battery and return it
to service.
Fully charge the battery and retest.
Failure to fully charge the battery
before retesting may cause false
readings. If CHARGE REQUIRED
appears again after you fully charge
the battery, replace the battery.
A REPLACE BATTERY result
may also mean a poor connection
between the battery and the vessel.
If you tested the battery using the IN-
VESSEL test, disconnect the battery
cables and retest using the OUT-OF-
VESSEL test before replacing it.
Thaw the battery and retest
24-volt system detected. Connect to
12V battery instead of the system.
