The
temperatures
for
rechargeable
batteries
are
as

Disconnect
the
charger’s
power
cord
from
the
receptacle
5.
Hold
the

How
to
make
the
batteries
perform
longer.
(1)
Recharge
the
batteries
before
they
become
completely
exhausted.
When
you
feel
that
the
power
of
the
tool
becomes
weaker,
stop
using
the
tool
and
recharge
its
battery.
If
you
continue
to
use
the
tool
and
exhaust
the
electric
current,
the
battery
may
be
damaged
and
its
life
will
become
shorter.
(2)
Avoid
recharging
at
high
temperatures.
A
rechargeable
battery
will
be
hot
immediately
after
use.
If
such
a
battery
is
recharged
immediately
after
use,
its
internal
chemical
substance
will
deteriorate,
and
the
battery
life
will
be
shortened.
Leave
the
battery
and
recharge
it
after
it
has
cooled
for
a
while.
CAUTION
○
When
the
battery
charger
has
been
continuously
used,
the
battery
charger
will
be
heated,
thus
constituting
the
cause
of
the
failures.
Once
the
charging
has
been
completed,
give
15
minutes
rest
until
the
next
charging.
