Wasn't there an issue some time ago where every time someone's neighbor used his garage door opener it powered up the BCU in his Range Rover P38 and drained his battery? :rofl:
That's funny, but it's actually something to consider. If you've been playing with a fancy Rover-specific scanner, you must be sure your BCU is going back to sleep when you're done.
You need to check for current drain, man. Be sure that's the issue first. Is it likely you just have terrible battery fortune? No, but it's possible. It's also possible you've got an irritable gnome crawling up into your engine bay every night to short the battery.
You have to remove variables by proving at least one thing to be probably true.
Once you are sure, rule out the alternator, which you've done by simply replacing it. That's not the end of the world, you'll have needed one eventually, and now you've got a spare.
The alternator may be an obvious culprit, but it's not the only potential source. It could be anything. Test for a drain, and then find out where it's coming from. If you can't be bothered to do so, or don't feel comfortable doing so, drop it off at a shop.
Electrical issues are simple to diagnose, but they require lots of time and patience when they are not obvious.
