Cycle
life
depends
strongly
on
factors
such
as
brands,
quality
and
conditions
of
batteries
as
well
as
rate
of
discharge,
cut-off
voltage
and
depth
of
discharge
of
batteries.
Depth
of
discharge
is
de?ned
as
the
level
to
which
battery
voltage
is
taken
during
discharge.
Dis
charging
to
less
than
the
recommended
voltage
is
known
as
over-discharge.
The
shallower
the
discharge,
the
more
cycles
the
battery
will
provide.
This
is
true
for
all
battery
chemistries.
