Businesses that rely on
technology for their day-to-
day operations cannot afford
to risk even a split second of
downtime, let alone an extended
outage. To keep information
technology, telecommunications,
factory floor and call center
operations running smoothly,
businesses have to take a close
look at their power infrastructure
to identify vulnerabilities and
take action to prevent costly
downtime.
Central to an effective power
infrastructure are UPSs. By
ensuring that consistent,
quality power is fueling critical
systems, UPSs provide a
first line of defense against
unexpected downtime and load
loss, and offer various levels of
redundancy, communications
and interoperability with other
power equipment. Despite
advances in UPS technology,
however, one truth remains the
same: when the power fails, the
UPS needs to draw its power
from banks of lead acid batteries
to feed the critical load until it
is able to start and synchronize
standby generators. It is well
understood that batteries are
the most vulnerable part of any
UPS and that battery failure is a
leading cause of power-related
downtime. The more customers
know about their batteries, and
the more detailed and current that
information is, the better their
chances of heading off disaster.

Cellwatch is an innovative
battery monitoring system for
large-scale technology install-
ations where power and system
availability are critical to suc-
cessful business operations.
Cellwatch is a powerful tool in
mitigating and preventing costly
downtime due to unexpected
battery failure.
Daily battery monitoring
increases overall system
reliability
Unlike other battery monitoring
systems, Cellwatch has been
specifically designed to monitor
the ohmic value of all jars in the
battery every day. By avoiding
random sampling of jars,
which can miss a failing cell,
Cellwatch dramatically increases
the likelihood of identifying
a potential problem before it
becomes a crisis. Cellwatch’s
unique design uses a very
light test load, combined with
superior electrical noise filtering
techniques, enabling timely
battery replacement or other
preventive action. Cellwatch
is a critical part of ensuring
availability and saving money by:

Cellwatch consists of three basic
components: the data collection
module (DCM), the battery
monitoring unit (iBMU) and the
control unit. It also offers an
optional generator extender kit.
The DCM is connected directly
to the battery cells or jars and
gathers the information on
battery health. The control unit
provides the interface between
the DCM and the iBMU. The
iBMU is a PC running the
Cellwatch application software
and provides the graphical
reporting on the status of the
battery system. The iBMU can
integrate with the BMS or NMS,
simplfying battery management.
The generator extender kit
enables the generator start
batteries to be monitored.
Cellwatch is the only system
that can monitor different
jar voltages with the same
system. Each DCM is capable
of monitoring two-, four-, six-,
eight- and 12-volt jars. This
capability enables Cellwatch to
provide a total solution, leaving
no critical batteries in the power
system unmonitored.
Cellwatch is ideal for applications
and industries that require long
battery runtimes, and where any
downtime can cascade into a
very costly scenario, including:
