一個2A電池擺入冰格會點?

YES. IF YOU USE IT IN FRIDGE.
The electric current generated by a battery is produced when a connection is made between its positive and negative terminals. When the terminals are connected, a chemical reaction is initiated that generates electrons to supply the current of the battery. Lowering the temperature causes chemical reactions to proceed more slowly, so if a battery is used at a low temperature then less current is produced than at a higher temperature. As the batteries run down they quickly reach the point where they cannot deliver enough current to keep up with the demand. If the battery is warmed up again it will operate normally.

NO. IF YOU STORE IT IN FRIDGE AND USE IT IN ROOM TEMP..
When a battery is not in use, it will slowly lose its charge as a result of leakage between the terminals. This chemical reaction is also temperature dependent, so unused batteries will lose their charge more slowly at cooler temperatures than at warmer temperatures. For example, certain rechargeable batteries may go flat in approximately two weeks at normal room temperature, but may last more than twice as long if refrigerated.

當睇到柏車君你呢條問題，我想起我曾讀過的一篇文章，題目是「如何讓『手機電池』起死回生」
內中也題到將電池放入「冰格」所將會帶出的結果。
今轉錄如下，僅呈 柏車君你參閱：
如何讓『手機電池』起死回生
　　當你的行動電話電池使用時間變短(記憶效應或老化)時,你是否會再買一顆電池來更換呢? 下次當你碰到這種情況時請省下你的錢,告訴你一個很有效的方法不妨試試看：
　　1.把電池用報紙包起來再放進塑膠袋裹包好放入冷凍庫三天(報紙可吸收多餘水份)
　　2.三天後取出常溫下放二天
　　3.二天後將電池充電,充飽後裝進行動電話裹測試(預估可救回80%-90%)
　　本訊息由知名電池廠商工程師透露,根據測試過的朋友指出效果相當有效.
　　至於有沒有效果,反正電池快沒用了,而且冰箱人人有,各位朋友不妨試試看吧!

希望你睇完呢篇文章後，再加上你親身的實驗，
會有出現令你滿意的答案吧！
