Additional Test Requirements
For a more decisive result the tester may require additional
information. The following messages and instructions may
appear before the analyzer displays the results of your test.
Surface Noise/Unstable Battery
The battery will hold a surface charge if the engine has been
running or after the battery has been charged. The analyzer
may prompt you to remove the surface charge before it begins
testing.
1. Follow the tester’s instructions indicating when to turn
the headlights on and off.
2. The analyzer will resume testing after it detects that the
surface 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.
After the Deep Scan Test the tester will either display the results
or give you the option to perform the 5-Minute Discharged
Battery Test. Although this test takes several minutes, it gives a
more precise result for difficult-to-diagnose batteries.
For a more decisive result, the analyzer may ask if you are
testing the battery before or after charging. If the vehicle
has just been driven, select BEFORE CHARGE. Press NEXT to
continue.
Battery Test Results
After the test the tester will display one of five battery
decisions with the complete results in a series of screens. Use
or
to scroll through each result.
To send the results to an IR printer, press PRINT. To return to the
Main Menu, press END, or to continue testing if you’ve selected
the system text, press NEXT. You’ll have the opportunity to
print all the results at the end of the System Test.

GOOD BATTERY
Return the battery to service.
GOOD–RECHARGE
Fully charge the battery and return
it to service.
CHARGE & RETEST *
Fully charge the battery and
retest.
Failure to fully charge the
battery before retesting may
cause false readings.
If CHARGE
& RETEST appears again after
you fully charge the battery,
replace the battery.
REPLACE BATTERY ** Replace the battery and retest. A
REPLACE BATTERY result may
also mean a poor connection
between the battery cables and
the battery. After disconnecting the
battery cables, retest the battery
using the out-of-vehicle test before
replacing it.
BAD CELL–REPLACE ** Replace the battery and retest.
* If the result is CHARGE & RETEST, the tester will calculate and display the
time needed to charge the battery at 10, 20, and 40 A.
** When testing at the jump start posts, the tester may need to verify the
result. It will give you the option of retesting at the battery posts
