電池の日(denchi no hi): Day of battery

There are so many anniversaries regarding November 11 which I have had no idea until today. November 11 is written as 1111 or 十一十一(juichi jyuichi) in Japanese, therefore most of them were decided by its shape. Among them one anniversary attracted my attention. That is day of battery.
Can you imagine why? Because eleven is written as 十一 (jyuichi) in Japanese character which looks like + and - , that is positive and negative of batteries. Don't you think it is interesting?
The day was established in 1986 by Nihon kandenchi kogyokai (日本乾電池工業会), Battery Association of Japan. Kandenchi (乾電池) means dry battery.
