WARNING
136) Battery fluid is poisonous and
corrosive: avoid contact with
your skin and eyes. The battery
recharging operation must be
F0V0380
performed in a ventilated place,
away from naked flames or
possible sources of sparks to
avoid the risk of explosion and
fire.
137) Don't try to recharge a frozen
battery: it must be thawed first,
otherwise it may explode. If the
battery was frozen, have it
inspected by specialised
personnel before recharging to
check that the internal elements
are not damaged and that the
casing is not cracked, which
causes the risk of leakage
of poisonous, corrosive acid.
