That depends on a lot of factors but the general answer is: Yes, probably; maybe 50 miles total.
BUT.....5 trips of 10 miles each wouldn't be as effective as one 50 mile ride......because of the 4 extra starts involved.
If you have a tender it certainly would be good to connect it overnight just to be sure......or at least long enough for the "green light" to come on......assuming that it has one.
The charging systems on modern bikes aren't very "robust" and sometimes will not fully recharge a really dead battery not matter how long you ride. Better to be safe because a battery ages a LOT faster if it remains partially discharged for a long time. (Automotive type batteries only.)
