我想問呢
用咩2A電芯最耐用呀？
我個FD 有部PENTAX S50
但食電好勁..
一個鐘都未有就差唔多冇電LA...
佢用panasonic 黃綠黑色o個隻電~~~
但影57張相都已經換電2-3 次......=.="

Sanyo 係唔係會勁過 GP, 我用 GP 2500 放落 A95 都映到 350-400 張~

三洋口碑品控幾好架!!

要用叉電電芯,唔好用普通2A電.相機廣告係呃人的,冇電可以隨街買結果就會係好快冇電

Alkaline batteries should be used as backup only in the following reasons:

1. Only about 1,000mAH for an AA alkaline battery;
2. The voltage of alkaline battery keeps declining on use. This is the property of an alkaline battery. During the middle of the battery life, the voltage keeps falling until it falls below 1.2V then the DC would shut down. So you can only used up about several hundred mAH.
