An apparatus for selectively charging a variety of batteries. A battery charging system includes a charging circuit, a processor, and a key, or identification device. The key has a value or code associated with the type of battery to be charged. The processor executes a software program that reads the value associated with the key. The software program charges the battery in a manner required by the battery type associated with the key value. In another embodiment, the program checks for changes to the key, such as when an operator swaps the key during charging.
