Why not pilot market the battery for something
like the razor or Black Berry with the
sale of a charger built to spec.
Is that possible? Business people need longer
battery life and dont want bigger batteries.
Seems like a natural. And have you experimented
with combining your battery with ultracapacitors to feed someone like CalCars Prius replacement? Seems like they would be a natural business partner for large footprint batteries.

Bob - third party chargers are certainly a possibility, although it does mean more expense for the end user and the battery company has to develop expertise in manufacturing the whole charger unit as well as the battery; usually those are manufactured by different suppliers. The third-party charger might impact the warranty, though I’m not sure many people would worry if it gave them a lot more battery. And of course you get lower volume of sales than if, say, Dell puts the battery in all its high-end notebooks. That makes being a supplier to the notebook manufacturer a more attractive proposition all round and it’s the route all the other battery folk have taken - which may show a route like yours could be a better answer.

On the ultracapacitor side, I’ve not seen anything but every aspirant battery technology company we’ve spoken to has talked about hybrid cars, either as an after-market replacement or pitching to the suppliers.
