Figure (A) above shows the voltage profile of a healthy battery during the
cranking of an engine. The graph starts off at the battery's nominal voltage,
and a voltage drop is detected when the vehicle is cranked. The voltage
recovers to the battery's nominal voltage and eventually rises to
approximately 14.4 V when the alternator starts charging the battery.
For Figure (B) where a typical 2 year-old battery, you noticed the
difference in the voltage drop which indicates that it is weaker but still
usable.
Whereas Figure (C) represents a very weak battery that can barely crank
a car and is due to fail in the very near future.
As voltage profiles can indicate the relative ability of the tested battery in
starting an engine, so there is no need for knowledge on the starter motor
requirement or the battery's rating and size.
MODEL 12-1015 will capture the highest voltage drop and calculate the
final results which should not be lower than 9.6V average during cranking
and computes the result after the test.
10.1– Begin Testing
1. With engine OFF, place
the vehicle transmission in NEUTRAL for Manual
and PARK for Automatic then apply the parking brake.
2. Connect the analyzer to the battery terminals and the display will light up
as shown (Fig 47).
3. After you have made your choice, selecting either “New: Clear Memory” or
“Continue…Test” will proceed to the display below: (Fig. 48)
