NOTE : Keep the packaging : Connection accessory & mounting option details are printed on the back.
IMPORTANT WARNINGS & CAUTIONS : Batteries emit explosive gases. Do not smoke or use matches in the vicinity of batteries
and avoid causing sparks or flames. Take great care to avoid short-circuits across the battery terminals which can cause battery
explosion, serious personal injury and even death. When working with batteries, ensure good ventilation. Battery acid is severely
corrosive and will cause burns in contact with skin & can cause blindness on entering the eyes, so wear protective eyewear and
clothing. In case of accidental direct bodily contact with battery acid, wash immediately with soap and water and get medical
assistance. Take maximum care to avoid the following : coming into personal contact with any hot or moving part of the engine or
vehicle; allowing any part of your clothing to do so; or accidentally fouling any hot or moving part with the TestMatemini, its connection
cable or connection accessories. Do not use the TestMatemini unless its connection cable & accessories are in good condition.
CAUTION : Batteries are very heavy. Do not attempt to remove a battery from a vehicle or to remount it on a vehicle unless you are
sure you have the necessary physical strength & skills while handling it to avoid risk of damaging the vehicle or dropping the battery
which could cause serious personal injury.
The TestMatemini is waterproof & dustproof (IP65 classification).
If you do not fully understand any part of these instructions, consult a professional before using the TestMatemini.
Connections and mounting accessories:- 3 screws are included in the packaging for mounting the removable backplate onto the
main enclosure. This should be done immediately unless you are intending to first fit the cable straps. In this case, mount the backplate
after inserting the cable straps as shown on the packaging. If the detachable battery clips become worn or corroded, replace them by
TecMate part number TM-74. The TestMatemini can also be connected to the battery through the optional accessories (detailed on
packaging) with metal eyelets which are are permanently fixed to the battery posts. One of these connection accessories is delivered
with TecMate’s AccuMate & OptiMate IIISP chargers.
Using the TestMatemini to test your battery and the vehicle’s charging system.
Step 1. Connect the TestMatemini. Carefully observing the above warnings and precautions, connect the red clip to the +ve / POS
battery post, then the black clip to the –ve / NEG battery post making sure the connections are good and cannot slip off.
In case of wrong connections, the TestMatemini circuit is electronically protected.
TIP: For accurate results always make the connections directly onto the the battery terminals. Connections away from the battery such
as the black clip to the chassis or red clip to a terminal on a current carrying conductor could result in erroneous readings.
Step 2. Battery voltage check : with the TestMatemini correctly connected and ignition switch, vehicle lights and power consuming
accessories switched off, the centre green LED (battery icon with V) should light. This indicates a battery voltage of 12,5V or more,
which is normal for a charged battery. A reading of 12V or less indicates a discharged or even a defective battery. Such batteries will
probably show a weak cranking voltage during the cranking test (step 3), in which case disconnect the TestMatemini (step 5), carefully
remove the battery from the vehicle and recharge it using an AccuMate or OptiMate brand charger, then reconnect the battery on the
vehicle taking great care to make the correct connections, and repeat steps 1, 2 & 3.
Step 3. Test the battery under cranking load : Switch off any vehicle lights or audio systems. With the TestMatemini securely
connected to the battery turn the ignition key (or press the starter button) to crank the engine while observing the TestMatemini
display. The voltage will drop sharply for an instant, then it should settle slightly higher until the engine starts.
GOOD – Voltage initially drops into yellow / green zone, settles in green zone.
ACCEPTABLE – Voltage initially drops into red / yellow zone, settles in yellow zone.
POOR – Voltage remains in red zone.
If a charged battery does not test “GOOD”, this is probably due to one of the following : (1) worn or defective battery; (2) factory fitted
battery at the limit of its capability due to increased engine compression (performance modifications); (3) design constraints (size &
weight) of performance motorcycles / vehicles / watercraft.
Step 4. Test the charging system alternator and voltage regulator : Once the engine has started during the cranking load test in
step 3, the vehicle's charging system will automatically come into circuit with the battery. The output voltage settings of voltage
regulators are designed to deliver the appropriate charging voltages for the type of battery with which the vehicle was factory-equipped.
The appropriate voltage at normal engine idling speed (800rpm or higher) should be 14V to 14,5V* (see NOTES below). Check your
vehicle's technical manual for the correct charging system voltage setting. If the charging voltage displayed is not as specified, have the
system professionally checked. An incorrect charging voltage setting will lead to premature battery failure.
*NOTES: 1) Some vehicles may require engine speeds of 2000 rpm or higher to deliver sufficient charge voltage.
2) On some models of motorcycles / ATVs the charging systems are low power. It may take a few minutes
(following cranking) before the appropriate voltage is reached.
3) A voltage of up to about 14,8V can be expected on a stationary vehicle with only the required / mandatory electrical
components powered up (e.g. headlight(s), ignition system, fuel injection ECM). TIP: Power up electronic / electrical
accessories that may be used during normal operation of the vehicle and check that the voltage does not drop below
14V at 2000 rpm / normal engine operating speeds. If it does, the battery may not receive sufficient charge and this
will lead to starting problems and premature battery failure.
4) On most motorcycles, ATVs & watercraft & on older trucks & cars, the battery forms part of the regulatory circuit. A
battery in poor condition (with increased internal resistance) may cause an abnormally high charge voltage.
5) Modern cars & trucks may be fitted with temperature compensated voltage regulators that vary charge voltage
according to ambient temperature (i.e. higher in winter, lower in summer).

Step 5. Disconnect the TestMatemini in the reverse sequence of step 1, observing the CAUTIONS detailed above.
