If the dry cell battery preserves improper, can appear the leakage the
phenomenon. How can let the battery long-term maintenance
electric quantity? First we light the candle to cause its melting, because the battery cathode must be smoother than the positive electrode, after therefore we even spread again the melted candle wipe are good on the battery cathode. Finally lays aside them in the dry well ventilated place. Like this may
effective avoid the leakage
phenomenon occurrence. This is because exposes in the air battery can have the redox reaction with the air in moisture content, causes the leakage. But spread the waxing young or up and coming generation in the battery cathode to arrive the insulation function, like this, regardless of travelled on official business in us, when traveling depositing battery backup, might the effective preservation battery capacity. Before use, so long as used the nail to dig out gently first the candle membrane may.
