Question:

How big of a battery will this charge. I am no longer using the little battery and have wired in the full size battery mounted on the tongue of my trailer. Will this trickle charge a regular size 12volt battery. Also if the batter from the truck is tied into the battery on the tongue why wont this charge the battery and for go the tricle charge.

I contacted our representative at Hopkins and he informed me that the Trailer Breakaway Kit Battery Charger, part # 20011 can charge batteries of different sizes, even large batteries, it will just take a bit longer. He informed me that part # 20011 will trickle charge your regular 12 volt battery just fine.

If you do have the vehicle battery connected directly to the battery on trailer it will keep sending power to the battery even after the battery is charged, which could be bad for the battery. With the Trailer Breakaway Kit Battery Charger it will stop charging the battery once it is fully charged.

To install part # 20011, you will connect the Black wire to the vehicles battery, connect the Red wire to battery on breakaway kit and connect Blue wire to breakaway switch. You will want to use, 10 Gauge Blue Primary Wire, part # 10-1-1, and quick splices, part # SWC501915-1, and use Ring Terminal, part # 44-5310A, to connect to battery.
