Abstract
A battery charging system detects if multiple battery cells to be recharged include rechargeable, secondary batteries or non-rechargeable, primary batteries. If the system detects that any one of the cells is a primary battery, then the charging system halts the charging operation. If all of the cells are secondary batteries, but the polarity of any battery cell is incorrect, then the charging system halts the charging process.
