2.2 Checking the battery
Method A for SEMI-TRAK and TUBULAR CELL:
Check acid density in the six battery cells with an acidometer.
Check each cell - max. difference between each cell 0.04 kg/l.
Method B for all three battery types:
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.

2.3 Battery charging
Charging must be performed with a charger correctly set with the charging voltage for
the battery type, see point 2.1. For connection and operation, see the instructions
accompanying the charger. The manufacturer recommends a charger of 20 amp
capacity. During charging, the temperature in the battery must not
exceed 50°C.Charging simultaneously with truck operation is not advised.
2.4 Warnings and information on battery
Avoid the use of naked flame in the vicinity of tubular cell and SemiTrak batteries. The
charging of tubular cell and Semi-Trak batteries gives off gases that can be explosive.
Therefore charging should be performed in a ventilated room. At temperatures around
freezing point, battery capacity is reduced by 30%.
