Abstract

The present invention provides a method of replacing secondary batteries. In the method, batteries can be replaced at a low cost and performance of an overall battery assembly can be maximized after the battery replacement. The battery assembly is composed by electrically connecting a plurality of secondary batteries in series or in parallel. When a portion of the secondary batteries is judged as defective, the defective batteries are replaced by replacement batteries. In an aspect of the method, voltage is detected for every predetermined voltage detection block unit concerning secondary batteries composing the battery assembly in order to judge defects of the secondary batteries in the voltage detection block unit. Batteries in a voltage detection block unit will be replaced with replacement batteries if they are judged as defective.
