Faced with divisions of opinion within the alliance, Chang Cheng-hung has his bottom line: On the one hand, the demands of each enterprise are different. Some companies want to mass produce the 5,000 hour formula; others would have more than they knew what to do with using the 2,000 hour version, so it would by no means be appropriate just to turn everything over in an undifferentiated way.
面對聯盟內部的種種歧見，張正弘有他的堅持：一方面每家廠商的需求不一樣﹘ ﹘有些廠可以做到五千小時電解液的量產，有些廠商只需要二小千時的就綽綽有餘，因此一視同仁、全部移轉並不見得最好。
