Battery Voltage

I have a 2010 X5 and I think my battery has been giving me problems lately. Although I drive it at least 3-4 days a week, it died on me in the past. At the time, I measured the battery voltage and it registered only about 11.89 V. I trickled charged it for a day or so and it's been fine now. However, I noticed that the voltage is always around 12.0-12.1 V when the engine isn't running. And sometimes after I haven't driven the car for a couple days, it sounds like it's hard to start the car when I start the ignition. It does start, but I feel like the battery has just enough juice to do so.

Is that normal?

I brought it into the dealership for my annual maintenance and mentioned it to them. They supposedly checked it out and said nothing was wrong though.
