The problem is that the cavity for the 2 AA cells that provide the memory backup is just a little too large for some batteries.  Mallory (Duracell) batteries in particular are problematic, as they're a little bit too small, and get jostled.  Energizers work a little better, but sometimes lose power too.  I've seen a number of cures published, involving soldering capacitors in to the circuit and the like, but the best, least invasive cure I've found is to wrap a little bit of scotch tape around the AA batteries, two or three turns, to effectively widen them a bit.  After I did that with my first 2010, I never had the memory loss problem again.
