At competitions: Before every match--you don't have enough matches to afford blowing one to a dead battery.

At home: As voltages start dipping close to or below 12V at rest, we swap them. (Under load, the robot will naturally dip below 12V as amp draws increase.) My team's process for this is far from scientific and we invariably run them a little long, so we tend to use our oldest batteries for practice first since they're already less likely to be the fittest battery for competition.

We (I) put some tips on the AndyMark website: http://www.andymark.com/battery-tips-s/615.htm.

(Full disclosure of the probably obvious: I work at AndyMark.)
