Warranty
This product carries a 2 year return to factory warranty,
we cannot he held responsible for carriage charges to or
from the factory or the cost of any work incurred in
replacing the item.
Where as legally all warrantees should go through the
persons supplying you the product, however, Sterling
recognises that due to the international nature of this
business and the time added to repairs that this is not
always the best solution, as such we are happy to help
direct from the factory if possible, please understand that
this help is at our discretion and not a legal requirement.
WARNING
Never test or charge a frozen battery.
To prevent sparks never disconnect ( or connect ) the
unit under test.
Always work in a well vented space.
Always wear safety goggles as battery hydrogen
explosions could happen.
This tester only works if the batteries are fully charged,
testing an empty battery is a waste of time.
Wear rubber gloves (not included) whenever working
with the Battery Tester or batteries.
Only test 1 x 12V battery at a time. For larger banks or
voltages they must be broken down to an individual
12V battery. No larger than about 140Ah / 1000 CCA.
Note: Before any testing, make sure to clean the battery
contacts. Ensure the battery is fully charged. When
connecting the tester to the charged battery, the battery
voltage is over 13.2V ( surface voltage ) the load test
will not engage, as the unit assumes that you want to do
the charging test only. It also prevents the unit being used
on 24-36V battery banks.
1) Make sure the vehicle is switched off. If a single battery,
up to about 1000 CCA or about 140Ah then you can test in
position. However, for example, a boat with 4 batteries,
each battery must be isolated (removing the pos from each
battery link would be fine). Test 1 at a time with a 2 minute
rest interval between each test, this allows unit to cool
down. For 24V, 36V or 48V battery banks they must be split
into their 12V components. Do NOT use this directly on the
24V, 36V, 48V directly as it will destroy the unit.
Only an individual 12V battery can be tested and the
battery must be fully charged.
Connect the red (+) Clamp to the positive (+) terminal post
on the battery. Connect the black (-) Clamp to the negative
(-) terminal post on the battery. If less than 12.4V is
displayed on a 12V battery, disconnect the battery and
recharge before testing. Adjust the Set CCA button to
correspond with the CCA of the battery. Push the CCA
button (increments of 100) until the CCA that matches your
battery appears. Maximum is 999CCA. After 999CCA, If
CCA button is pressed again, the charging system mode
will be activated, “AAA" is displayed. As a measure of
good practice round your battery CCA number DOWN
to the nearest hundred, do not round up.
2) Check the Battery Tester LED Window (5) to determine
effectiveness of charge. If the Battery Tester does not
register and no display is seen, double check that the
clamps are connected to the proper terminal posts. Make
certain a clean connection has been made between the
clamps and terminal posts.
3) Push and release the LOAD button (8), a solid and
consistent measurement is indicated by the Battery Tester.
Within five seconds, read the LED Window display during
the test. Do not test more than three times in a five minute
period. Allow one minute for cool down between tests.
Note: If a battery does not have the charge expected,
have a qualified technician check the specific gravity.
There may be an electrical drain or charging system
trouble. If charging does not raise the specific gravity, you
may have a defective battery.
Operations (Continued)
Analysing test results by colour display: The Battery
Tester will measure battery output/charge in two ways.
The three lights above the LED Window (D ) will indicate a
colour telling you the general condition of the battery.
Red: Bad, No Charge, or Completely Discharged
Yellow: Weak, Needs Recharging
Green: Good or Normal - Has Existing Charge
4) If the battery is without significant charge, charge it
and check it again under load test. The battery should
measure at least 75% of Open-Circuit Voltage. 75% can
be considered fully charged. lf the charging rate reaches
at least 75% but fails to reach 75% after the load test, it
needs replacing. Refer to the table below for 12V battery
percentages:
Note a recently charged battery will have a surface
voltage, this can give false impressions of the actually
battery state. The below table refers to a battery which has
been left for a day or so, it is, however, impossible to judge
the state of the battery by this voltage alone, hence the
tester.
5) When test is complete, remove Black Clamp (-) from
battery first; then remove Red Clamp (+).
Testing the Charging System (Alternator / Regulator /
Charger Output):
WARNING: When testing a system in a car/truck, the
vehicle must be on a flat, dry surface. The transmission
must be in park and the emergency brake engaged.
1) Connect the red (+) Clamp to the positive (+) terminal
post on the battery. Connect the black (-) Clamp to the
negative (-) terminal post on the battery.
2) With the engine off, check the Battery Tester voltmeter
display for a voltage reading. If the Battery Tester does not
register any voltage, double check that the clamps are
connected to the proper terminal posts. Make certain a
clean connection has been made between the clamps
and terminal posts.
Other things which can be tested with this product
using the voltmeter only and not using the load test.
Alternator / Battery Charging System check
Attach the positive and negative clips from the tester to the
battery. The tester should start up. To enter ‘charging
system test’ repeatedly press ‘Set CCA’ button until ‘AAA’
appears on the display. The voltmeter should then
reappear, however, you are in ‘charging system test’
mode. If you then attach your charging system, whether it
be an alternator or battery charger and turn on charging
system the tester will determine whether the charging
system is ‘Good’, ‘Weak’ or ‘Bad’. The user can, therefore,
get some idea about the condition of their charging
system as well as their batteries.
