Saft nicads are about one-third of the cost per mile of Optimas, but 
about double the cost per mile of flooded lead.  This is because they 
have a very long cycle life -- 2500 to 3500 cycles.  For many people the 
upfront cost is tough to swallow, though -- about $8,000 for a 144 volt, 
100 amp hour (at 100 amps) pack.

NiMH and Lithium have quite a distance to go yet before they are 
affordable for normal civilians.
