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
capacity in the respective battery dimensions
for the truck series.
Electric trucks must not be p

area for any longer than nece
ssary. This also
applies to unused batteries
. The charging
station and the parking area
for trucks and
batteries must be at normal r
oom temperature
(not below 10°C). Charging i

at low temperatures. At temp
eratures below
10°C, the battery cannot be f
ully charged with
the usual charging paramet
ers.
– Charge the battery fully before each shift.
– During the gassing phase, always top up
with distilled water.
The distilled water will m
ix 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.
