Method and apparatus for minimizing battery corrosive electrolyte leakage
Battery corrosive electrolyte leak is decreased by using an adjustable mechanical retention device to bias a plurality of batteries toward a first end of the series configuration wherein the adjustable mechanical retention device creates a snug mechanical fit at a bottom surface of the metal can of the terminal battery. When the device in which batteries are being used is a flashlight, a two-piece tail cap can be used, an inner member of which is driven by an outer member, and tail caps of existing flashlights can be replaced so that a strong tail cap spring no longer provides a biasing means against the terminal contact of the terminal battery.
Battery corrosive electrolyte leakage is reduced by absorbing forces generated during impact of a device holding the batteries and preventing such forces from being transferred to terminal contacts of batteries held in a series configuration. Contacts of batteries connected in series are protected by use of shock absorbing spacers while a terminal end shock absorber is positioned so that the terminal end will be cushioned when a force is applied to the series configuration causing the batteries to move relative to the terminal battery.
