✔ 最佳答案
其實電池放電既時候內裏會產生氣體(氫)
佢會阻住電池放電
所以電池放電能力弱~
但放幾日,D氫冇左~
就會有番D電~

同埋係電池入面有d化學物質會同氫結合而整走佢[[通常變做h2o,,氫係絕緣體,,會減低電壓,,咁等一陣,,比d時間個d化學物質同氫做反應咪有番d電囉

after few day,
some gases and oxides formed at the carbon rod will decrease.
reaction in the cell will occur shortly and electricity will then be produceded

It can refill itself, but just can use a monent then cannot use.
