of only 32 °F (0
°C).
Allow a frozen battery to
thaw completely before attempt ing to charge it

again
because
the
battery casing
can be
cracked
due
to
ice
formation and can
leak
battery acid.
Battery charging
(Maximum
charging rate of
30 amps/14.8
Volt)
When charging at
low
voltages (e .g
.
with a
trick-
le
charger), the
battery
cables do
not have
to be
disconnected first. The battery caps should
not
be opened when charging a
battery.
It
is
not
necessary

Fast charging the battery
(charging
rate
above 14.8 Volts)
For techn ical reasons do
not
us
e a battery charg-
e
r
that
uses voltage greate
r
than
14

- Battery acid that may spill during charging
should be washed off w ith a solution of
warm water and baking soda to neutralize
the acid
