Random low battery issue.
Mini just recently began to experience not having enough juice to start although all other electricals work okay. It jump starts okay. I tested the alternator and it's fine. I just replaced the battery but the situation is still ongoing. Think it's a lemon battery or starter issue? Nothing else seems to but staying on that would drain the battery. I checked the battery with a multimeter and first time read 12.7, the next day was 12.2 and there was no driving done either day.

The cable terminals at the battery post look okay, guess I'll trace them to the other ends, I know the + goes to the starter solenoid but not sure if - is to the block or where, I can google that probably. I just recently put on a catless downpipe and this issue began a couple of weeks later. It maybe just a coincidence though, I didn't see any significant cables/wires in the area. Thanks.

May have found the issue. I put a charger on it when I got home last night, went to disconnect this morning and the + cable terminal was loose so I readjusted and retightened. Not sure what happened, I made sure it wouldn't twist when I replaced the battery. Hopefully this does the trick.

For future reference, the Wal-Mart battery did fit but did not have the reserve capacity that Mini's require thus all the post shutoff operations were creating a deficit on that battery. I've had good experiences normally with the Wally batteries to this point but just doesn't fly with these cars.
