Abstract
A emergency battery charger includes a secondary cell contact structure for connecting a rechargeable battery to be charged (the secondary cell) with a primary cell power supply consisting of one or more conventional batteries having an aggregate voltage higher than a rated voltage of the secondary cell, thus providing a DC to DC charger that can be used once in emergency situations. The secondary cell contact structure for connecting like polarity terminals of the primary cell power supply and the secondary cell may be contained in the same housing as the primary cell power supply or in a separate housing, and the charger may include such additional elements as an on/off switch, voltage or current detectors and a central processing unit, a circuit breaker, and/or a current limiter.
