Will Discharged Trailer Break Away Battery Affect Normal Trailer Brake Operation

Question:

I have a towmaster trailer and i know the battery on the breakaway system is dead because it has not been in use for a long time. but will that effect the trailer from stopping not having a good battery or should the trailer stop regaurdless when hooked up to the truck and stopping ?

Expert Reply:

The fact that your break away battery is dead will not affect normal braking function. However, should your trailer somehow became uncoupled from the tow vehicle and the pull pin for the break away system was pulled, the break away system would not operate the brakes.

The # HM20008 replacement battery you mentioned would be a good replacement for a Hopkins or TAP break away system or a # TK2023 for a Tekonsha break away system.
