Batteries from Sony

Comparison of batteries from Sony (measured on postal scale Adam Oranchak and Steve, Tue Jan 16 20:36:56 EST 1996):
NP-500: 3.4oz, 21.6kJ (6v nominal assumed), 6.35kJ/oz, 406J/cm^3 (size/cm=7*3.8*2);
BP-L60: 30.95oz, 194.4kJ (12v nominal assumed), 6.28kJ/oz, 309kJ/cm^3
BP-L90: 45.9oz, 289.44kJ (12v nominal assumed), 6.3kJ/oz, 284kJ/cm^3
Zinc air are lighter, we believe, but much less power density (perhaps suitable for making into a large garment type distributed supply).
