More convenient still, I've found, is to get a couple of ring terminals with diameter large enough to accept the bolts that normally connect the sticks in the pack. Undo all the bolts (thus eliminating the risk of current from all the batteries), and use a couple of the metal stand-off pieces (the thick metal "washers") that are in the terminals that are outside connections to screw the ring terminals to each stick to charge it. A cordless drill with a 10 mm socket is a great help here.
