original Mac Portable (which I
 know is not what you're referring to). ?The portable weighed 16lbs, due in

 Yes, that was my guess, too. Only laptop-/style/ portable I ever even
 heard of with a lead-acid battery. 
 PowerBook 100. Basically a repackaged Portable.

The Sharp PC-5000 also had a lead-acid battery; according to them, L-A
has a longer shelf life, charges faster, and is actually smaller and lighter
for the same power than the NiCds of the day.
