Abstract
A retrofit module for lithium battery passivation, detection, activation and maintenance (PDAM) may include a test circuit, a load circuit, a microcontroller and means for electrically connecting the PDAM module to a target battery in a device. Upon power-up and/or joining or rejoining a network, and additionally at periodic intervals thereafter, the state of the target battery is determined and an activation algorithm is executed, the parameters of which are dependent upon the determined target battery state.
