Abstract
A battery and charging system including a charger (200) that provides a current and a battery (107) having at least one cell (108) that can be charged by the current provided by the charger (200). The battery (107) includes a memory (110) that stores battery information and a coding resistor (111) indicative of battery type. A battery switching circuit (113, 114) coupled to the memory (110) and the coding resistor (111) switches the memory (110) into contact with the charger (200) when the charger (200) is capable of reading the memory (110). Otherwise, the battery switching circuit (113, 114) switches the coding resistor (111) into contact with the charger (200).
