Cell capacity and output resistance can easily be determined from the curve resulting from these measurements. A similar article appeared in the April, 2006 issue of Elektor Electronics. Introduction Rechargeable AA cells are very popular for a large variety of portable applications. The number of brands is also high and the cell quality can differ considerably. Cell capacity is sometimes differen……
