4.2 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.
DENSITY
1.26 - 1.28 kg/l
Fully charged
1.19 - 1.20 kg/l
1/2 charged
1.16 - 1.17 kg/l
1/4 charged
1.10 - 1.11 kg/l
Discharged
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.
Approx. 12.7 V
Fully charged
Approx. 12.2 V
1/2 charged
Approx. 12.0 V
1/4 charged
Approx. 11.6 V
Discharged
4.3 Battery charging
Charging must be performed with a charger correctly set with the
charging voltage for the battery type, see point 4.1.
The manufacturer recommends a charger of 10-15 amp capacity.
During charging, the temperature in the battery must not exceed
50° C.
Charging simultaneously with truck operation is not advised.
4.4 Warnings and information on battery
Avoid the use of naked flame in the vicinity of tubular cell and
Semi-Trak 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%.
