Instructions and Installation
BREAKAWAY BATTERY CHARGER INSTALLATION
1
12 Volt Sealed Lead-Acid Battery
To maximize the life of the battery the following
conditions should be met:
1. Avoid over or undercharge. This is the
single worst enemy of lead-acid batteries.
2. Batteries should not be stored in
a discharged state or at elevated
ambient temperatures.
3. Avoid exposing batteries to heat!
Service life is shortened considerably
at ambient above 30°C (86°F).
4. Due to the characteristics of this battery,
after six to nine months of storage,
the battery should be recharged.
5. Charge the battery at the proper rate.
Current should be limited to 1.2 amps
or less.
6. Provide adequate air circulation when
charging battery. Do not charge battery
in any other container besides the
supplied battery box.
7. CAUTION Do not place batteries in
close proximity to objects which can
produce sparks or flames.
8. Do not expose battery case to organic
solvents or adhesives.
9. CAUTION Do not attempt to disassem-
ble batteries. Contact with sulfuric acid
may cause harm.
10. CAUTION Fasten batteries tightly and
make provisions for shock absorption if
exposure to shock or vibration is likely.
11. WARNING Do not throw batteries into
fire; batteries so disposed may rupture
or explode.

1. Remove Charger and Battery from
the battery case.
2. Mount battery case securely to
frame, jack post or other suitable
location on trailer.
3. Bolt Breakaway Switch✼ to frame
of trailer or battery case bracket.

Important Facts to Remember
1. CAUTION Improper installation of the
breakaway battery will destroy the brake
control. The negative (-) terminal must
attach to ground and positive (+) terminal
must attach to the breakaway switch.
2. WARNING Check your Breakaway
System✼ periodically to insure that
wiring and connections are secure.
A short or an open circuit can result
in a no-brake condition.
3. If excessive discharging of the
breakaway battery occurs, check
battery and recharge using a Heavy
Duty Two Stage /Maintenance Charger.
If using a commercial (AC to DC)
make certain the 12 volt charge is
limited to 1.2 amps or less.
4. If the secondary battery needs charging,
current will be drawn from the tow vehi-
cle’s battery at anytime the tow vehicle is
connected to the trailer. The most current
which will be drawn is 1.2 amps.
5. To only charge the breakaway battery when
vehicle is running, a battery isolator may be
installed in the 12 volt supply line (BLACK
wire for tow charger).
READ THIS FIRST:
Check condition of battery prior to
installation and prior to each trip.
