Self-Discharge
All NorthStar NSB BLUE+
®
batteries
will discharge over time once charged,
even in storage. Higher storage
temperatures increase the rate of self-
discharge. Fully charged, the natural
(“rest”) voltage of all NorthStar NSB
BLUE+® batteries is approximately
13.0 Vdc. A battery should have a
freshening charge (see page 16) if its
rest voltage is below 12.2 Vdc per
battery (2.03 Vdc per cell or VpC).
A battery should not be used if its rest
voltage is 12.0 Vdc or lower upon
delivery. Contact OutBack Power
upon receiving a battery in this state.
Storing NorthStar
NSB BLUE+
®
Batteries
The NorthStar NSB BLUE+
®
batteries
must be given a freshening charge
every 24 months when stored at
77°F (25°C). If stored in higher
temperatures, the charge should be
more often.
Capacity
Battery capacity is given in ampere-
hours or amp-hours (Ah). This is a
current draw which is multiplied by the
duration of current flow. A draw of
X
amperes for
Y
hours equals an
accumulation of
XY
amp-hours.
Because a lead-acid battery’s chemical
reaction constantly releases energy, its
amp-hour capacity is affected less by
lighter loads. The battery has greater
capacity under lighter loads.
For example, if the NSB190FT BLUE+
®
is discharged at the 20-hour rate to a
voltage of 1.75 VpC (a load expected
to effectively drain 100% of its capacity
in 20 hours), it will be measured to have 202.4 amp-hours. However, at the 2-hour rate,
a heavier load, only 152.2 amp-hours will be measured. For all tested discharge rates and
amp-hours, see Table 3 on page 26.
