purposely draining and recharging?

It depend on the type of batteries that are used, and the circuitry in your
equipment:

If the radio has some circuitry that switches it off when battery power gets
low, there is no risk of damaging the batteries by emptying them too much.
Similarly, if the charging circuitry is smart enough, charging will stop or
go into "trickle" mode when the battery is full. (usually you can tell the
smartness of the charging circuitry, if there is some indication of the
state of charging it's smart, if there is not, be careful, read the manual
and do not overcharge too long).

For NiCd it is advisable to charge and discharge in full cycles, i.e. fully
charge and then fully dischage, otherwise they'll "remember" the shallow
cycle and keep less charge.
For other types like Lithium or NiMh it does not seem matter much what
pattern they are charged and discharged. Only because of their high
self-discharge I keep NiMh batteries in a trickle-charger until I actually
need them, and I usually top-up my Lithium cells before a trip as well.

Kees
