(家電維修) 歐樂B 電動牙刷 換電池 ! Oral-B electric toothbrush replacement battery! 

電動牙刷用了幾年後 , 電池一定會損耗。如果購買高價的電動牙刷，
因此無法使用。一定會不捨得。只要花個小錢(NT:135元)換個電池就OK啦。
一起來DIY吧。
After using an electric toothbrush for a few years, the battery will definitely wear out. If you buy a high-priced electric toothbrush,
Therefore it cannot be used. Will be reluctant. Just spend a small amount of money and change the battery.
Let's DIY together.
