Voltage Explanation
Normally, it is 100% charged when the battery voltage is 12.60V or above.
•
100% Charged = Battery voltage 12.60V or above
•
75% Charged = Battery voltage 12.45V
•
50% Charged = Battery voltage 12.15V
•
Discharged condition = Battery voltage less than 12.00V
Operating Instructions
If testing batteries of low-frequency use, it is necessary to cycle (charge and discharge) the
battery several times before testing, normally 3-5 times will achieve a reliable test result.
Only after cycling the battery can the chemical properties of the battery be restored. This is
particularly important after long periods of no use. If after 3-5 times of battery charge and
discharge, the battery health state is still lower than 60%, battery replacement should be
considered.
1.
To extend battery life, Low use batteries, should be recharged every 2 months.
2.
Please turn off the engine before testing.
3.
When charging is finished, do not test immediately. Wait at least 10 minutes to allow
the battery charge to stabilise, then test. Even when testing an in vehicle battery, after the
engine is turned off (for the most accurate results) wait 10 minutes before testing.
4.
In general, if the battery voltage is below 12.40V, recharge it.
Before Testing
Before testing, use a wire brush (not included) and alkaline cleaner (not included) to clean
the battery terminals, as any surface resistance on the terminal will negatively affect the test
result.
Before testing on an, in-vehicle battery, ensure the ignition key is turned off. Make sure there
is no power drain from any other vehicle electronics and keep the car doors closed so interior
lights do not illuminate.
Attach the red test clip to the battery positive terminal, the black test clip to battery negative
terminal. Note: Tester has an automatic reverse polarity protection, if accidentally
misconnected it will not cause any adverse effects.
In order to ensure a good electrical connection with no resistance, please wiggle the test
clips on the terminal posts a few times when connecting.
The tester draws its operating power from the battery being tested; it will only operate when
connected to a battery with more than 6 volts available. For this reason, the battery analyser
will not operate if connected to a dead flat battery.
