正当香港的玩具、电子表、成衣及手电筒等在国际市场上骋驰纵横之际,另一项港制产品亦于这三年间,脱颖而出跃居世界产销量首位——那就是钮型电池。但现此同时之传统式炭锰干电池产销量却不断下降。 钮型电池本由美国首先制造,但不久,香港与日本紧随发展,至一九七七年,香港始正式投入生产,而至一九八○ While Hong Kong’s toys, electronic watches, ready-to-wear garments, and flashlights are on the international market, another Hong Kong-made product has also emerged as the world’s top-ranking producer and sales leader in the past three years – that is, button batteries. However, at the same time, the production and sales of conventional carbon-manganese dry batteries have been declining. Button batteries were originally manufactured in the United States, but soon Hong Kong and Japan followed their development. By 1977, Hong Kong was officially put into production, and up to 1980.
