Structure of the data records
Static voltage history
In the static voltage history, it is possible to read out the following battery voltages:
● 12.5 V
● 12.2 V
● 11.5 V
The previous 4 entries, or "time stamps", are displayed.
Display on tester
Static voltage < 12.5 V : 46 hours
Static voltage < 12.2 V : 18 hours
Static voltage < 11.5 V : 9 hours

Structure of the data record
Prolonged deviations below 12.2 V and 11.5 V are particularly critical.
If the battery voltage is below these threshold values, the battery will not be able to regenerate. This can result
in damage to the battery after a lengthy standstill period.
If lengthy deviations below 12.2 V and 11.5 V are ascertained, the battery must be tested.
The data are recorded under the following test conditions :
– Terminal 15 OFF for at least 2 hours
– Convenience CAN bus in Sleep mode
– Power consumption less than 100 mA

2005-06-28 Date: year, month, day Time stamp
10:12:00 Time: hours, minutes, seconds
005 Time in hours which the actual voltage is below the set voltage, e.g. 12.5 V
001 Battery number
0012 Total time in hours which the actual voltage is below the set value. Only specified for fourth value.
The total may be larger than the total of the previous 4 entries, because all deviations below the voltage
threshold are counted for the battery which is fitted.
