I found MICROCELL from their website. After confirming the customizable needs about customized alkaline batteries, they replied that they can do modification as requested! They were very patient to explain design of my own brand battery label & packaging for me and provided professional suggestions based on what I wanted or needed in order achieve success with extending business into other dry cell manufacture fields "I choose them because it's hard enough trying find good suppliers these days without having any room left over when its all said done"
