The demand is expected to grow, especially in renewable energy applications, according to MarketsandMarkets. The widespread use of lead-acid batteries impacts the economy, environment, and public health. Proper recycling and handling are crucial to mitigate
Free QuoteThe reason is that lead-acid batteries normally form bubbles on the plates during charging. And these get big enough and then rise. Some chargers will periodically reverse the charging voltage polarity for a moment in order to force the bubbles loose so as to keep them small, as the bubbles interfere with re-plating lead from solution back onto the plates, forming unwanted filaments of
