I don't advise lifting the heavy X5 battery into position when you are tired. Those dang cables are right in the way and if one is not paying attention one can make contact with those cables. Not such a bad thing if you are putting the battery in with the terminals in their correct position. If one puts it in with the terminals reversed, well then things get exciting and expensive (both door controllers went poof too...).
Lots of learning of which circuit goes where and my Fluke got a heavy duty workout chasing voltage...
