For any and all types of trailers with electric trailer brakes, a CURT breakaway kit provides you with the equipment you need to be prepared. We offers three different complete breakaway systems to accommodate various trailer sizes and meet your specific towing needs. All of our breakaway kits are tested for your safety and meet DOT requirements for holding and breakaway situations. The CURT Soft-Trac 2 breakaway system comes with a 12-volt, 5-amp battery and a nylon breakaway switch for reliable activation. The battery is designed to be rechargeable for long-term use, and the breakaway switch comes with a 48" lanyard to fit most vehicle-trailer combinations. This particular kit also includes a 12-volt battery charger. To keep the battery well-protected from the elements and to allow for convenient mounting on your trailer, this Soft-Trac 2 breakaway kit also comes with a top-load battery case. The case is made from durable plastic to be rust-free and features a metal mounting bracket with a 3-1/8" hole, to mount on the trailer tongue or on a jack post. Nobody hitches up a trailer expecting a breakaway, but that doesn't mean you should tow unprepared. Be ready for anything with a CURT breakaway kit.

The Curt Breakaway Battery Charger is a 12-volt lead-acid battery system designed for trailers with electric brakes. It provides power to the trailer's brake control and breakaway switch. The system includes a sealed lead-acid battery (P/N 1023 or 2023), a charger that automatically recharges the battery when the tow vehicle is connected, and a breakaway switch that activates the trailer brakes if the trailer becomes disconnected from the tow vehicle.
Two battery options are available: P/N 1023 (4 amp/hr capacity) and P/N 2023 (5 amp/hr capacity). Both are 12-volt sealed lead-acid batteries with identical dimensions (3.54" L × 2.76" W × 4.13" H) and weight (3.8 lbs). Both have a maximum discharge current of 40 amps and a 20-hour discharge rate of 225 mA (P/N 1023) and 250 mA (P/N 2023). The choice between them depends on your power requirements.
The Curt Breakaway Battery Charger is designed for trailers with electric brakes and a breakaway switch. It provides 12-volt power to the brake control and breakaway switch. However, the manual does not specify compatibility with all trailer types or brake systems. Contact Curt Manufacturing at 1-800-738-8713 or 1-800-786-7968 to confirm compatibility with your specific trailer and brake system.
The system includes a 12-volt sealed lead-acid battery (P/N 1023 or 2023), a charger, a battery case, a breakaway switch, and wiring. The manual does not specify all included hardware or fasteners. Contact Curt Manufacturing at 1-800-738-8713 for a complete parts list.
Mount the battery case securely to the trailer frame, jack post, or other suitable location on the trailer. The manual does not specify a preferred location or provide clearance requirements. Ensure the mounting location is secure and protected from damage.
Yes. Check the condition of the battery prior to installation and prior to each trip. This helps ensure the battery is in good working order and ready to power your trailer's brake system.
Wire the system per the schematic diagram provided in the manual. The negative terminal must attach to ground and the positive terminal must attach to the breakaway switch. Improper installation will destroy the brake control. The manual includes two wiring diagrams: one with a charger and one without. Properly insulate all connections. The manual notes that wire color coding is not standard among manufacturers, so wire by function only.
Feed wires out the back of the battery case, then close the top. The manual does not provide additional routing instructions or clearance requirements. Contact Curt Manufacturing at 1-800-738-8713 for detailed routing guidance.
P/N 1023 is a 12-volt sealed lead-acid battery with 4 amp/hr capacity. Dimensions: 3.54" length × 2.76" width × 4.13" height. Weight: 3.8 lbs. Maximum discharge current: 40 amps. 20-hour discharge rate: 225 mA. Terminals: Fasten Tab .187" × .032". Maximum charge current must be limited to 1.2 amps. Service life: 4–5 years in standby applications or 200–1000 charge/discharge cycles depending on depth of discharge and rate of charge.
P/N 2023 is a 12-volt sealed lead-acid battery with 5 amp/hr capacity. Dimensions: 3.54" length × 2.76" width × 4.13" height. Weight: 3.8 lbs. Maximum discharge current: 40 amps. 20-hour discharge rate: 250 mA. Terminals: Fasten Tab .187" × .032". Maximum charge current must be limited to 1.2 amps. Service life: 4–5 years in standby applications or 200–1000 charge/discharge cycles depending on depth of discharge and rate of charge.
Maximum charge current must be limited to 1.2 amps or less. Charge current above 2.3 amps will result in shortened service life. If using a commercial AC to DC charger, ensure the 12-volt charge is limited to 1.2 amps or less.
The maximum current drawn from the tow vehicle's battery is 1.2 amps. This occurs when the secondary battery needs charging and the tow vehicle is connected to the trailer. If you want to charge the breakaway battery only when the tow vehicle is running, a battery isolator may be installed in the 12-volt supply line (BLACK wire for tow charger).
A battery isolator is an optional device that can be installed in the 12-volt supply line (BLACK wire for tow charger) to ensure the breakaway battery charges only when the tow vehicle is running. This prevents the breakaway battery from drawing current from the tow vehicle's battery when the tow vehicle is not running. The manual does not provide installation instructions for the battery isolator.
The negative terminal must attach to ground and the positive terminal must attach to the breakaway switch. Improper installation will destroy the brake control. This is the most critical safety requirement for the system.
A short or open circuit can result in a no-brake condition, meaning the trailer brakes will not function. Check your breakaway system periodically to ensure that wiring and connections are secure.
If excessive discharging of the breakaway battery occurs, check the battery and recharge it using a Heavy Duty Two Stage/Maintenance Charger. Ensure the 12-volt charge is limited to 1.2 amps or less. Excessive discharge may indicate a problem with the charging system or a parasitic drain.
To maximize battery life: (1) Avoid over or undercharge—this is the single worst enemy of lead-acid batteries. (2) Do not store the battery in a discharged state or at elevated ambient temperatures. (3) Avoid exposing the battery to heat; service life is shortened considerably at ambient temperatures above 30°C (86°F). (4) After six to nine months of storage, recharge the battery. (5) Charge at the proper rate (1.2 amps or less). (6) Provide adequate air circulation when charging. (7) Do not charge the battery in any container besides the supplied battery box. (8) Fasten batteries tightly and provide shock absorption if exposure to shock or vibration is likely.
Check your breakaway system periodically to ensure that wiring and connections are secure. The manual does not specify a recommended interval. Regular inspection helps prevent no-brake conditions caused by loose connections or corrosion.
Under normal operating conditions, the battery has a service life of 4–5 years in standby applications or 200–1000 charge/discharge cycles, depending on the depth of discharge and rate of charge. Proper maintenance, including avoiding overcharge and undercharge, and keeping the battery cool, will help maximize service life.
Do not place batteries in close proximity to objects that produce sparks or flames. Do not expose the battery case to organic solvents or adhesives. Do not attempt to disassemble batteries (contact with sulfuric acid may cause harm). Do not throw batteries into fire; batteries so disposed may rupture or explode. Do not store batteries in a discharged state or at elevated ambient temperatures above 30°C (86°F).
The system is designed for trailers with electric brakes and a breakaway switch. Confirm compatibility with your specific trailer by contacting Curt Manufacturing at 1-800-738-8713.
