EagleTac Protected 18650 3100 mAh Rechargeable 3.7V Li-Ion Battery

Product Review (submitted on September 3, 2012):
IMO, about the highest capacity and highest quality 18650 Li-Ion battery available. Eagle Tac uses Panasonic 3100mAh cells, made in Japan. Pricey but you will find the useable charge capacity to be far longer than comparable batteries.
