So, as I predicted, my old battery box would not charge (despite religiously checking to make sure the batteries were not fully run down over the winter - except for the last month).
I have replaced it with the "new" box, which is working (who knows for how long). I am going to open the old box up and if I can get the motor to run, may try and replace the battery pack with a hand built one from some good quality Sanyo or such rechargeables.
Before I do that, I may try and "shock" the old batteries into a recharge (again, if the motor works). Sometimes NiMH batteries won't recharge if one or more of the set is completely dead but the others are OK. I have read that if you use a higher voltage charger for a very brief period (less than a minute), it can "force" enough charge into the dead batteries to allow the original charger to do its work. I'll report back if I have any good news.
Otherwise, I LOVE the idea and HATE the implementation.
