1.28, before they are used for the first time.
The battery is fully charged when the battery voltage and the acid density are not •
changed between two measurements made with an interval of two hours.
Check at least once a week at the end of the charging that the battery has a cor- •
rect acid density (1,26-1,28 kg/l at 20°C).
Please note! If the battery is discharged more than 80%, with an acid density below
1,13 kg/l, the battery life will be shortened. Discharge of maintenance-free batteries
(GEL): Maximum 70%.
Method B
To measure the voltage, use a digital voltmeter (DC) on the battery poles. The truck
must not have been in use for the previous 30 minutes.
Method A
Check the acid density in the battery cells with an acidometer.
Check each cell - max. difference between each cell 0.04 kg/l.
Density:
1,28 kg/l Fully charged
1,22 kg/l 30% discharged
1,18 kg/l 50% discharged
1,13 kg/l 80% discharged
Voltage:
Ca. 25,40 V Fully charged
Ca. 24,70 V 30% discharged
Ca. 24,20 V 50% discharged
Ca. 23,80 V 70% discharged
Ca. 23,50 V 80% discharged
