User Note:
To enable the heating circuit on your battery a connection from the heat-enable post to the positive terminal needs to be
made. The heater will automatically activate when the internal temperature drops below approximately 35°F (1.6°C) and
will shut off when the internal temperature exceeds approximately 45°F (7.2°C).
If the battery has been exposed to below-freezing temperatures for a long period of time without the heater enabled, it
will take 2 to 4 hours for the internal components of the battery to heat up enough for the battery to accept a charge. The
heater will continue to operate until the battery disconnects for low-voltage cutoff.
REMINDER: ALWAYS DISCONNECT THE HEATER WHEN STORING THE BATTERY.
Enabling the Heat Function for a Single Battery:
To install a single heat battery, you will need the standard heat-enable jumper wire. See Figure 2.
Use the provided jumper to connect the
POSITIVE
terminal and the heat-enable post. The terminals are labeled and color-
coded:
r
ed for positive (+)
,
black for negative (
–
)
. See Figure 5.
Figure 5: heat-enable Jumper Wire Setup
Step One: Making a Connection on the Positive Terminal
The 5/16” side of the
heat-enable jumper wire should go on the positive terminal connection
between
the washer
and the nylok. See Figure 6. The
connection should then be torqued down using a ½” wrench, a ½” socket, and a
torque wrench set to 10 ft-lbs.
Figure 6: Proper order of hardware to connect cables. When going from left to right in the diagram the correct order is:
bolt, washer, lug, terminal, washer, jumper wire, and nut. If multiple lugs are used, they should be on the same side of the
terminal.
Note
The heat-enable post is not current-carrying, so when a connection is made it should not spark.
However, once the connection has been made to the heat-enable jumper wire, the connection will be live at
12V. Take care to avoid any contact with other live wires or grounds.
