CAUTION
Risk of component damage!
The lead-acid batteries must not be left in the cold
store overnight without power uptake or charging.
–
Charge the battery outside the cold store
and operate the truck using a replacement
battery.
Using batteries in the cold store
To compensate for the reduction in capacity at
low temperatures, it is advisable to use lead-
acid batteries with the maximum nominal ca-
pacity in the respective battery dimensions for
the truck series.
Electric trucks must not be parked in a cold
area for any longer than necessary. This also
applies to unused batteries. The charging sta-
tion and the parking area for trucks and batter-
ies must be at normal room temperature (not
below 10°C). Charging is extremely slow at
low temperatures. At temperatures below
10°C, the battery cannot be fully charged with
the usual charging parameters.
–
Charge the battery fully before each shift.
–
During the gassing phase, always top up
with distilled water.
The distilled water will mix with the battery
acid so that it does not freeze.
Water top-up systems must not be used at
temperatures below 0°C, as this could cause
the systems and the water present in the hose
lines to freeze.
The battery voltage when discharged is thus
generally lower at low temperatures. The final
discharged voltage is reached earlier, i.e. the
capacity is lower.
