Pricewise, using normal retail prices on reasonable quality cells...
For equal voltage and capacity:
The lead acids are $4200 US weighing 424 kg
A123s would need 40s38P so 1520 cells at about $7600 US weighing 106 kg
D cell NIMHs would be 120 in series, 8 parallel for 960 total at $1100 weighing 157 kg
Some Priuses and other hybrids essentially use D cell Nimh packs. At first they seem like the winner by far... Except the lead acids can produce 1000+ amps easily, the A123 pack would be rated to about 1100 amps but the nimh would be rated to 240 amps. So you'd need 4 times the batteries working out to $4400 US and 628kg. So 50% heavier than the lead acids for the same current, but then you have 4 times the capacity. But that's a LOT of weight and range likely isn't their primary concern.
