Canon 20D 裝上直倒掣後, 粒原裝BP-511A電勁快顯示無電, 但係取下直倒掣後, 裝翻電上去又顯示滿電,係唔係個直倒掣有問題.....今晚係天祥剛剛買.... :-(

我都有咁既情況... 當我將兩舊電調位，電力顯示就回復正常... 我諗係bugs 之一...

[clivemilk]

Is there any dust / stain on the contact points.

I got two 511A, sometime use both together, sometime use one and the other stand-by, never happen like your case.

In better way, go back to shop and change it.

但直度係無保養的. 過左7日就冇得換

[yellow1314]

咁不如你＄７００賣個直倒俾我呀！！

黃一生一世, 你都幾大咬bor

佢肯收壞野，冇奶油用大咬形容∼ >__<

我用2A電仲死
影唔夠十張/一分鐘就冇電

[beerman]

個2A電架係做樣咋∼昆你買！！！
以為好抵咁，我都受昆……
佢說明書都講明緊急時用。

頂20D唔順，點解KM D7D個直倒行AA電同行鋰電差不多，Canon又唔得??
