Basic Understanding of the Low Current Charge and High Current Charge for Lead-acid Batteries

Abstract

We have discovered that a low current long charge for lead-acid batteries is very beneficial towards recovering the original Ah capacity or maintaining the initial full capacity. Most recent commercial chargers are designed for high rate quick charging. These commercial chargers include those installed in trucks and busses. In this paper, the nature of the chemical reaction in the charging process of the negative electrode is discussed in order to understand the benefit of the low current charge.
