Recharging
A CAUTION
III
When
the
battery is being activated, hydrogen and oxygen
gases in
the
battery are extremely explosive. Keep open
sparks and flames
away
from
the
battery
at
all
times,
especially when charging the battery.
III
When charging battery, remove battery
vent
plugs.
• When disconnecting the cable
from
the
battery, start
with
the
negative terminal first. When connecting
the
cable
to
the
battery, start
with
the
positive terminal first.
III
Never check battery charge
by
placing a metal object across
the
posts.
Use
a
voltmeter
or
hydrometer.
1) Slow Charging
1.
Add distilled
water
if
the
electrolyte level
is
low.
When
charging,
the
amount
of
electrolyte should
be
slightly
lower
than
the
specified level
to
prevent overflow.
2.
Connect
the
battery
to
the
charging
unit,
following
the
manufacturer's instructions.
3.
As
the
electrolyte generates
gas
while
charging, remove all
port
caps.
4.
The
electrolyte temperature must
not
exceed
40°C
(10S
OF)
during
charging.
If
it
exceed 40°C
(1
05
OF),
decrease
the
charging amperage
or
stop charging
for
a while.
5.
When charging several batteries in series, charge
at
the
rate
ofthe
smallest battery in
the
line.
III
NOTE
III
Slow charger operation
differs
with
the
type
used. For
details, refer
to
the
manufacturer's instructions.
2)
Quick Charging
1.
Determine
the
proper charging current and charging
time
with
the
tester attached
to
the
quick charger.
2.
Determine
the
proper charging current
as
1/1
of
the
battery
capacity.
If
the battery capacity exceeds
50
Ah, consider
50
A
as
the
maximum.
III
NOTE
III
Quick charger operation
differs
with
the
type
used. For
details, refer
to
the
manufacturer's instructions.
Directions
for
Storage
1.
When stori ng the tractor
for
long periods
of
ti
me, remove
the
battery from tractor, adjust the electrolyte
to
the
proper
level and store in a dry place
out
of
direct sunlight.
2.
The
battery self-discharges
while
it
is
stored.
Recharge
it
once every three months in
hot
seasons
and once
every
six
months in cold
seasons.
