Any battery that is used in a breakaway system on a trailer needs to be able to sustain full braking power to the trailer brakes for at least 15 minutes to be in compliance with various laws in regions that require breakaway kits. The batteries we sell meet the requirements and where designed for that purpose for 2 axles. Always make sure that brake away batteries are fully charged before using them.
