Now it is always good to get prototypes for mobile devices especially when it comes to fuel cell batteries, the question is “Will the all new Panasonic prototype Fuel Cell battery be good?
Panasonic recently announced 2 new Fuel Cell battery prototype for mobile devices, as far as the source below says there is no improvement to the battery life with a maximum 20W output, but Panasonic have however worked very hard indeed to reduce the battery by half the size.
So the battery life is no different but the overall size of the battery has changed, smaller always equals better and then only in time the life will get better. Even though the battery is smaller you will still get a cool 20h of battery lifespan (200cc).
