Today's radios are not able to determine the chemistry type battery connected and as such can not adjust the radio low voltage threshold indicator accordingly. This is especially a problem with new chemistry types such as Li Ion which have a lower and flatter discharge curve than NiCad. The use of the existing NiCad low voltage threshold for a Li Ion battery will cause the radio to prematurely indi- cate low battery. Hence a need exists to allow the radio to dynamically adjust the low voltage thresh- old corresponding to chemistry battery type.
