Do not confuse Watts (rate) with Watt-hours (capacity).

As I said, you don't have a 2kWh NiMH battery that weighs <20lbs... it would be closer to 90lbs of NiMH cells, plus a housing.

Ah*V=Wh. I got 2kWh from the Ah*V you posted in the OP, which you've since corrected. Based on the new numbers, we're looking at 0.02kWh, or approximately zero. A molehill next to the 0.5kWh mountain that is a D51-R yellow top Civic battery, which itself gives "meh" fuel economy improvement.

Also, a NiMH cell IS a deep cycle battery.
