Hmmm, I'm looking at page 19 in the HV20 manual (PDF version) and I see the following charge times listed:
NB-2LH 130 min
BP-2L13 200 min (this is the battery that comes w/ the HV20)
BP-2L14 225 min
FWIW--third-party battery resellers will typically list Canon-equivalent BP-2L12 p/n, in addition to the BP-2L14 one; the BP-2L12 will work in a HV20 as well.
