Seems to be a great battery and fits right in the battery box of my haulmark motorcycle trailer. The hitch and coupler locks are great. They too fit perfectly and so much easier they are keyed the same. Exremely fast shipping and great communication by email from etrailer. I ordered another part from another company two days before ordering the battery from etrailer. It's still not here. I highly recommend etrailer. I will not get any trailer parts or accessories anywhere else from now on.48392

I needed a new 12 volt battery for my utility trailer break-away brake. I found what appeared to be a direct replacement on etrailer.com based on the good description and high resolution picture on the website. I placed the order and the battery appeared two days later. The battery was exactly what I needed. The quality was good and the size was as advertised. The terminals were the right size and in the right places. Based on service like this, etrailer is the first place I look for my trailer and towing needs.45086

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

Expert Answers about Breakaway Kit Replacement 12 V Battery - HM20008                                           Do you have a question about this Accessories and Parts?


  • Does Break-Away Battery for a Haulmark Car Trailer Comes Fully Charged
  • The break-a-way battery does ship fully charged but after sitting on a warehouse shelf it may be a good idea to trickle charge for a few hours once received.

  • 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 Hopkins Breakaway Kit Replacement 12 V Battery # HM20008 Replace Tap 12V 5A 20 Hour Battery
  • I contacted our representative at Hopkins and he confirmed that the item you selected, Breakaway Kit Replacement 12 V Battery, part # HM20008, is the replacement battery that you need. He also informed me that the Tap brand is under the Hopkins name now.

  • 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

  • Troubleshooting Break Away System on Horse Trailer Towed by 1999 F350 and 2006 F150
  • It sounds like the power from the tow vehicle is not reaching the battery and keeping it maintained. As I first step, I would recommend testing the pin on the trailer connectors for the F350 and the F150 and make sure that the pin that provides 12-volt accessory power is still functional. You can use a circuit tester like part # 40376. On a 6-way connector, the hot pin will either be in the center of the connector, or in the 9:00 position. For a 7-way connector, test the pin in the 5:00 posit

  • Installing a Battery on a Trailer and Wiring it to Run Interior Trailer Lights
  • I recommend a 12 volt car battery rather than a breakaway battery because you may end up needing the larger battery down the road. What you will do is attach a battery box (see link for options) to the trailer frame. From the trailer side 7-Way connector, there will be a wire attached to the pin in the 11:00 position (if looking at the face of the plug). This is the 12 volt circuit. You can attach that to the positive terminal of the battery. It will maintain the battery but it will not up c

  • Are the Terminals on the Hopkins Trailer Breakaway Kit Battery F1 or F2 Terminals
  • From what I understand, an F1 connector is 0.187 inches wide (3/16 inches). I went out to the warehouse and pulled a Hopkins battery, # HM20008, to measure the terminals. They are indeed 0.187 inches wide. That would make them F1 terminals.

  • Can a Trailer Breakaway System 12 Volt Battery be Charged Using a Traditional Trickle Charger
  • A trickle type of charger can be used to charge a break away battery like # HM20008 as long as the charger is designed for a 12 volt battery. You might want to first have the battery tested to see if it has a charge. A local auto parts store can do this for you. You can also pull the pin on the trailer breakaway switch and see if the brakes engage. Sometimes, on the Engager breakaway systems, moisture can cause the indicator to not function properly. If the battery tests fine then you may just n
