I was delighted with the arrival of the break-away battery. It was exactly as described and was charged and ready for use. My greatest appreciation goes to etrailer for the rapid response and arrival of the battery. I requested standard shipping. etrailer offered, without additional charge, priority shipping getting the battery to me within two days. WOW!!! 16694

  • Will the Replacement 12V DC Battery Breakaway Battery Fit on My Circle J Trailer
  • The Hopkins Replacement 12V DC Battery, part number HM20008 should work with your breakaway kit. With this battery if your trailer has brakes on 2 axles or less the breakaway switch will function properly. You should make sure it will fit in your breakaway unit (sounds like it will) and that the connectors are compatible with your units connectors. You can zoom in on the product picture and see the connectors very well by clicking on the link below the product picture.

  • Does the Breakaway Kit Replacement 12 V Battery, Item # HM20008, Power Trailer Lighting
  • The Breakaway Kit Replacement 12 V Battery, item # HM20008, is designed to power the trailers brakes in a breakaway situation, and is not designed to power the auxillary lighting in your trailer. You will need to have a battery attached to the trailer frame for the trailer lighting and accessories. Your trailer lighting can also be powered by the towing vehicles electrical system with the addition of a 7-way trailer connector and wiring. this connector will also charge the trailers battery if

  • Can a Breakaway System Battery Charger Charge a Car Battery to Power a Trailer Mounted Winch
  • There are a couple of different things going on. First, a 12 volt circuit from a trailer connector will not be able to charge a battery, it will only be able to provide a maintenance charge, maintaining the charge level of the battery but not adding anything to it. While it may be sufficient for smaller breakaway batteries, it will not be sufficient for a 12 volt automotive or deep cycle battery. I recommend using a dedicated battery for the breakaway system, like the Engager Trailer BreakAwa

  • Best Way To Charge A Breakaway Battery and a Winch Battery
  • Using the breakaway battery charger to charge another battery on the trailer is not recommended. The larger battery you are using to operate the trailer winch would take an extremely long time to charge with a breakaway charger and would likely never charge fully with the limited amount of time the trailer is connected to the vehicle, even if towing long distances. The breakaway battery may not be charged sufficiently in this situation either. The best bet for charging the winch battery is to

  • What is the Life Expectancy of a Break Away Battery for a Trailer Break Away System
  • There are so many factors that can be attributed to battery life that a hard number of years for the life span of a Breakaway Battery like # HM20008 is nearly impossible to determine. In cold weather climates like in the northern United States, the cold will take its toll on the battery and it will not last as long. The same is true for hot climates such as in the Southwestern United States. And there are also marine areas, and/or areas that see a lot of rain. In addition to weather there

  • Can a Larger Breakaway Battery Be Used to Operate Interior Lights On a Trailer
  • You will want to use a separate, standard 12 volt deep cycle trailer battery to operate the interior lights. You will NOT want to use the trailer breakaway battery. The breakaway battery is not designed to power other trailer accessories or lighting, it is just designed to operate the breakaway system. The DOT regulations state that a trailer breakaway system needs a dedicated battery. You will be able to maintain a charge on the separate trailer battery by running a 10 gauge power wire like
