I sure didn't use 5 tons of CO2 to unbolt 4 bolts that held the engine on, so it would have to be in producing the lead acid batteries. But I hope it doesn't take 10,000 pounds of CO2 to make 400 pounds of batteries.

If using hydro, it's close to 1MJ/gram of CO2 according to Wikipedia. Recycled lead takes around 5MJ/Kg for cradle to grave in a lead acid battery. The plastic in the batteries was like 30MJ/Kg. The acid was almost zero MJ/Kg.
