The
equalization
charge
should
last
24
hours.

Charge
after
discharge
Batteries
should
be
charged
in
time
after
discharge.
The
method
is
recommended
as
constant
current
and
limit
voltage
charge.
Charge
the
battery
group
on
the
constant
current
of
0.1C
10
A
～
0.2C
10
A.
When
the
average
voltage
is
up
to
a
settled
voltage,
the
charging
current
will
decrease
automatically.
Keep
the
constant
voltage
till
end.
The
settled
voltage
could
be
float
voltage.
But
when
depth
of
discharge
is
heavy,
such
as
more
than
10%,we
recommend
to
set
up
equalization
voltage
so
that
charge
will
be
more
sufficient.
We
can
also
decide
voltage
according
to
initial
current.
If
the
current
is
larger
than
0.05C
10
A,
we
recommend
to
set
up
equalization
voltage.
Normally
Charging
Time
is
24hours.
We
can
judge
charge
time
according
to
Fig.
3
‐
4.
Usually
in
condition
of
constant
voltage,
the
value
of
charge
current
hasn’t
varied
for
continuous
three
hours,
charge
can
be
finished.
We
can
raise
current
if
the
battery
group
need
to
charged
in
a
short
time,
but
not
higher
than
0.25C
10
A.

Storage
Batteries
will
experience
self
‐
discharge
in
open
circuit.
The
result
is
that
the
voltage
of
open
circuit
is
decreased,
and
the
capacity
also
decreased.
During
storage
please
note:
a.
The
self
‐
discharge
rate
is
related
with
ambient
temperature.
The
self
‐
discharge
degree
is
smaller
when
the
ambient
temperature
is
lower,
otherwise
is
larger.
The
requirement
temperature
of
Narada
polymer
batteries’
storage
environment
is
from
0
℃
to
35
℃
.
The
storage
place
must
be
clean,
ventilated
and
dry.
b.
An
important
parameter
in
storage
is
open
circuit
voltage,
which
is
related
with
density
of
the
electrolyte.
In
order
to
avoid
permanent
damage
to
the
plate
caused
by
self
‐
discharge,
the
batteries
should
be
supplementary
charged
if
they
have
been
stored
for
six
months
or
open
circuit
voltage
below
2.10V/cell.
The
equalization
charge
method
should
be
adopted.
c.
All
batteries,
which
are
ready
to
store,
should
be
fully
charged
before
storage.
It’s
suggested
that
record
the
storage
time
in
the
periodic
maintenance
record
and
record
the
time
when
another
necessary
supplementary
charge
should
be
made.
d.
The
quality
certificates
of
GEL
batteries
record
the
latest
charge
time
of
the
batteries,
next
charge
time
can
be
calculated
according
to
this
charge
time.
