1) More than several hours to recharge- not on a high frequency opportunity charger try 15 - 30 mins to bring it to 70% n 8 hrs to complete the charge cycle 2) Swapping out batteries is time consuming (down time). Down time of approx 5mins 3) Half the range of a hydrogen fuel cell... w/ 2x the cost 4) Storage of replacement batteries (takes up a lot of valuable space). True 5) Large battery charging rooms are the rooms that there changed in... 6) Batteries in storage needs to be constantly monitored and charged. Nope not with today's technology w/ the smart chargers. 7) Sulfation true 8) Corrosion true 9) Explosion from overcharging again not with the smart charge al though I bet hydrogen would be worse if it exploded. 10)Lose approximately 14% of their speed over the last half of the battery charge (GenDrive fuel cells maintain constant power at all times). True but is it worth saving 14% more speed and spending 3x the cost?
