Vampire Draw on Trailer Breakaway Kit Battery Charger

Question:

Hopkins 20007 Break-Away Battery Charger Your Part Number 20011 The last chargers we installed in our cargo trailer caused both our lighting and our breakaway batteries to go flat after a period of not using the trailer the trailer sits about 6 months of the year unused. Both circuits are independent and each battery has their own charger. We determined this by looking for mA draws off the battery. After much bad language we discovered our cheap chargers were the cause. Does this charger protect against vampire draw?

There is not a breakaway kit battery charger, including the Hopkins # 20011 that will eliminate vampire draw completely. I do strongly recommend taking a look at the help article I added on trailer breakaway kit installation. Going by this should help you maintain your battery charge if by some chance you have not wired yours the same way.
