STARTER TEST:
Note: Before the starter can be properly tested, make sure the battery or battery-pack SOC (state of charge) and battery
condition tests GOOD and the engine is OFF.
To test the Starter, press the ON/OFF button to turn on the remote.
“MATCO MBT400”
will appear momentarily on the display.
Press TEST. The display will show the following screens. Select TEST BATTERY & STARTER. Follow the screen sequence as
below. See the next section for the charging system screen sequences.

2- 12V batteries in
parallel: add rated
capacities of single
battery. Pack is still
12V.
2- 12V batteries in series: add 1/2
rated capacities of single battery.
Pack is 24V.
In Vehicle Tests
BATTERY TEST:
Connect the MBT400 Battery Module to the battery to be tested. The green
Ready
LED and the yellow
Activity
LED will
blink. Press the MENU ON/OFF button to turn on the remote. “
MATCO MBT400
”
will appear momentarily on the display
and then the display will show
WAITING TO CONNECT
. When connected the green LED will stop blinking and the display
will show
IN VEHICLE TEST? PRESS YES (
←). The display will then prompt the user to
SELECT BATTERY/SYSTEM
VOLTAGE
. Press the
+ UP
or
- Down
buttons to select the battery or battery pack voltage i.e. 6V, 8V,12V, 24V, 36V to be
tested.
NOTE
: When testing the battery in the vehicle, make sure vehicle engine is
not
running and all accessory loads are
off
. If
SURFACE CHARGE
(SOC) is displayed, turn on accessory loads (lights, AC or heater) for 15 seconds with engine off.
Testing Battery Packs:
The MBT400 tests battery packs when they are connected to the vehicle as though it is testing a single battery. When testing
a battery pack, enter the battery voltage and rating of the pack as a single battery.
Batteries in parallel
: For batteries connected in parallel, add the rated capacity of each single battery to determine the rated
capacity of the pack. For example two 500 CCA batteries in parallel would have a rating 1,000 CCA (see figure below). The
voltage of the pack remains the same regardless of the number of batteries in the pack. The MBT400 can test batteries in
parallel up to 3500 CCA.
Batteries in series
: A pack consisting of 2 single 12V batteries in series would have 24V. The rated capacity of the two 12V
batteries in series is ½ the rating of the single battery. For example two 500 CCA 12V batteries in series would have a
rating of only 250 CCA. The M
BT400 can test two 12V batteries in series
IMPORTANT: The MBT400 determines the condition of the pack as whole but does not determine the condition of the
individual battery in the pack. If the condition of the parallel pack is determined to be bad, disconnect the batteries from the
pack and check each battery individually.
