There are many very specific tables, graphs, and circuits on the web. The
manufacturer usually has all kinds of specs on the battery. You can do a
search for them and come up with a number of examples. However, I go by the
following for the 7.2 packs:

1/10 current capability for fast charge (some chargers hit it harder than
this - makes them very warm)

1/30 for trickle (or even less if you are going to leave it on for a long
time - 1/50th works)

8.5 volts max. If you look at the 'cheap' chargers, they usually charge at
1.4 volts per cell.  (I've certainly screwed that one up before - but my
battery packs are still working)
