Interesting idea. Capacity equates to about 115mAH (.310WH / 2.7V) and thats to zero output, so not an endurance option. Robert G8RPI

I still have the reference without the batteries which went for recycling long ago, the possible new twist I've not seen noise data on is not batteries but Ultracapacitors intended for regenerative breaking: http://www.maxwell.com/products/ultracapacitors/products/d-cell-series It's nice to try something new and being new might be a way to sidestep environmental concerns.
