Chapter 7: Battery Test
Battery Test Results
After the test, the analyzer displays a battery decision with an
analysis in a series of screens. The analysis includes the battery
state-of-health (SOH) and state-of-charge (SOC). See Table 3:
Battery Decisions for an explanation of the battery decisions.
Use the UP or DOWN ARROW key to scroll to each screen. To
return to the Main Menu, press the END soft key. If you are
performing a System Test, press the NEXT key to continue with
the Starter System Test.

State of Health (SOH)
The battery’s state of health represents its general condition,
and therefore its ability to deliver the specifi ed performance
compared with a fresh battery.
Although a poor state-of-health can be the result of defects
in construction, it is most often caused by normal wear, which
depends on vehicle needs, climate, and operating conditions.
These cause irreversible physical and chemical changes within
the battery until it can no longer hold a charge and supply
the power to start the car and provide auxiliary power to the
electrical system. As the battery approaches end of life, its
deterioration accelerates until it fi nally fails to start the vehicle.
Before failing, the battery may start the vehicle under normal
conditions but may not be able to operate in more extreme
conditions. Extreme heat or cold could expose a weak battery
and cause it to fail.

Decision
Recommended Action
GOOD BATTERY
Return the battery to service.
GOOD–RECHARGE
Fully charge the battery and return it to service.
CHARGE & RETEST
Fully charge the battery using a Midtronics Diagnostic Charger 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
A REPLACE BATTERY result may also mean a poor connection between the battery and the vehicle. If
you tested the battery using the System test, disconnect the battery cables and retest using the Battery
Test before replacing it.
BAD CELL–REPLACE
Replace the battery.
WARNING:
Do not charge the battery. Charging a battery with one or more bad cells could
cause an explosion and serious harm to the user.
SIDE POST TEST
Test data was inconclusive using the side post. Retest using side post adapters.
JUMP START POST
Data was inconclusive using the jump start post. Retest at the battery terminals.
24V
24-volt battery detected. You are attempting to test in-vehicle both batteries in a 24-volt system.
Disconnect the batteries and test them individually.
