點解zinc carbon cell 要remove from electrical appliances?

因為呢種電芯耐咗會爆槳，而嗰啲槳會令啲電器損壞，所以要將呢啲電芯拎出嚟。
拎咗出嚟會唔會一樣爆槳?其實一樣會。

the zinc carbon cell is coated with a layer of zinc.
when it reacts with oxygen in air, the zinc layer will be thinner.
after some time, the electrolyte in the cell will leak and damage the appliances
