General Information
The Model 441-10A battery back-up sump pump system is not
a substitute for a primary sump pump. It is designed to
temporarily provide backup to a primary sump pump during a
power outage or other problem that prevents normal operation of
the primary pump.
Install this system during a time when the primary pump will not
be needed. If this is not possible and water will enter the sump pit
during the installation process, an additional pump may be
required to keep the pit dry.
The Model 441-10A back-up pump will activate when the sump
water triggers the back-up pump’s float switch. The system will
continue to operate automatically until the issue with the primary
pump is corrected, and for as long as the charge in the battery
installed with the system lasts.

Battery Back-up Pump
The Model 441-10A back-up pump system flow rates are directly
tied to the voltage the battery supplies to the pump while it is
running. The flow rates shown in Table 1 were generated by
supplying the 441 pump with 12.1V at the battery terminals. When
the battery supplies the pump with more than 12.1V, the pump’s
flow rate will be greater than those shown; likewise, flow rates will
be less when the voltage is less than 12.1V.

Charger
The charger is designed to continuously charge, maintain peak
charge, and monitor battery health. With AC power applied, the
charger can be left unattended and will not overcharge or damage
the battery. It will also monitor and notify the user via an alarm
and horn if the battery is no longer suitable for use.
The time the charger takes to recharge a battery depends on the
battery’s reserve capacity and its current state of discharge. The
charger takes no longer than 19 hours to charge a healthy battery
to a maintenance charging point. For more detailed information,
refer to Charger Operation on page 10.

Battery
The total time the battery back-up can operate in standby while
the AC power is off greatly depends on the battery installed with
the system. Liberty Pumps recommends using a Liberty Pumps
StormCell® Group 27 or Group 31 Deep Cycle AGM or Wet Cell
lead acid battery with the 441 system. StormCell batteries have
been specifically designed to maximize reserve capacity time (the
time the battery can operate continuously before it needs to be
recharged). Additionally, StormCell batteries have been modified
to provide the highest resistance to battery plate degradation due
to repeated charging and continuous maintenance charging. With
a charged Group 27 or Group 31 deep cycle battery, this back-up
system can expect to operate for 4.25 hours continuously or up to
6 days cycling on 4 times an hour, moving 10 gallons of water at
10 feet of vertical head.
Note: In an emergency when the system’s deep cycle battery has
been depleted, any 12V automobile battery, or other lead acid
battery, may be used to keep the back-up pump operational. Be
sure to replace the deep cycle battery back into the system as
soon as possible. Automobile batteries have much lower reserve
capacities and require frequent, repeated charging that will result
in early battery failure.
Assembly Methods
A check valve is required in the primary sump pump
discharge pipe to prevent water from recirculating back
into the pit.
Always install the back-up sump pump as close to the bottom
of the sump pit as possible.
All assembly methods require the back-up pump float switch
to have free movement.
There are three ways to assemble and install the battery back-up
pump, depending on sump pit diameter/depth and desire for a
truly redundant back-up system. Select appropriate method by
referring to Figure 1. Any method is acceptable, but Method A is
recommended. Examples are shown in Figure 2 as a visual aid.
