Have one of those and unless it's wired wrong the battery still goes dead.
Did you follow the instructions to wire it? It doesn't use the 7-pin connector. The wires in the umbilical with the 7-pin connectors are too small. You must use the supplied wire and have a second umbilical with it's own connectors.
Or you can wire it up to the 7-pin connector but you still need to use the supplied wire through out. That's how I did it. Here's a pic of my umbilical.
