Abstract: A battery testing and monitoring system specifically designated to continuously monitor overall battery voltage, conditions of individual cells or cell groups such as voltage, current and temperature as well as individual cell or cell group failures, conduction path failures and other conditions. The system is a portable or permanently installed unit having connectable thereto a programming/display/printer terminal which enables the programming of the monitor with various failure conditions as desired and also enables the printing of a permanent rocord of any testing procedure. Additionally, portable load units may be interconnected with the inventive monitor and the battery or batteries which are being tested and monitored so as to enable the testing and/or monitoring of such battery or batteries under controlled load conditions.
