ABSTRACT:
In this invention for totally eliminating the fire and/or electrical hazards associated with maintaining batteries for both automobiles and aircraft use, a weighted disconnect link is connected to an internal battery cell jumper. This link is arranged to bridge the center two cells of the battery by positioning the weighted link into the spring clips of the cell bridge lugs, thus completing the circuit within the battery. The section of the battery that houses the weighted link will be totally isolated from the electrolyte and explosive gas. An access door is provided in the battery for contact cleaning and maintenance if it should be necessary. This door provides a means to re-engage the link manually after it has been tripped by adequate G force. The G force is the key to the functioning of the system. When a sudden force is applied to the battery (a force strong enough to cause structural damage to the vehicle in which the battery is installed), the weighted link will displace itself, removing all electrical potential from the battery terminals and attached wiring. The link will tend to disengage the instant an adequate force is applied, and since only a very short distance is required to effectively open the internal circuit, all power will be removed from the terminals and the wiring before the frame becomes distorted to the extent necessary to cause major structural damage, shorting of high amperage electrical wiring and possible subsequent fire.
