  • Battery packaging and interconnection scheme
    Patent number: 5405715
    Abstract: A terminal for a battery assembly is adapted to lose electrical conduct with a battery cell in the presence of gases within a battery chamber thereby disabling the battery. The disabling of the battery assembly gives the user an indication that the battery is defective and should not be recharged. Additionally, because the battery is disabled, no more gases will be formed in the battery assembly so the seal or the protective envelope will not burst exposing the battery cell to the environment.
