Well, if you can charge the batteries seperately that's
probably the best idea, because unless the batterries have
been connected in parallel, they will be at different
voltages... and as soon as you connect them, the higher one
will start discharging itself into the low one. This will
heat them both up and make charging less efficient no matter
what you've got hooked up to the circuit to charge them.
