Sanyo has announced a new shape of battery called “pin.” style. Shaped a sort of like a thinner AAA battery, the “RU665” is a rechargeable lithium ion cell intended to be used in MP3 players, wireless headsets and pretty much anything else in need of a small(er) battery. At half the volume of AAA and a quarter the volume of AA, expect a capacity of 120mAh and voltage of 4.2V from this series set to be introduced summer of this year.
