(1個好電池+1個差電池的使用效果=2個差電池的使用效果)。","shipping_methods":[{"name":"7-ELEVEN取貨付款","fee":0,"currency":"TWD"},{"name":"郵局掛號","fee":0,"currency":"TWD"},{"name":"離島配送","fee":0,"currency":"TWD"},{"name":"萊爾富取貨付款","fee":0,"currency":"TWD"}],"lowest_shipping_fee":null,"payment_methods":["ATM轉帳","信用卡一次付清","萊爾富取貨付款","7-ELEVEN取貨付款"],"category_id":"2092104064","category_name":"電子零件/材料","breadcrumb":[{"id":"23336","name":"電腦、平板與周邊","url":"/tw/%E9%9B%BB%E8%85%A6%E3%80%81%E5%B9%B3%E6%9D%BF%E8%88%87%E5%91%A8%E9%82%8A-23336-category.html"},{"id":"2092072621","name":"耗材與線材","url":"/tw/%E8%80%97%E6%9D%90%E8%88%87%E7%B7%9A%E6%9D%90-2092072621-category.html"},{"id":"2092104064","name":"電子零件/材料","url":"/tw/%E9%9B%BB%E5%AD%90%E9%9B%B6%E4%BB%B6-%E6%9D%90%E6%96%99-2092104064-category.html"}],"view_count":0,"watch_count":3}
