The present invention, a cell layer edge support, provides longer battery cell life while minimizing the possibility of shorts within the cell. More specifically, an edge support layer is positioned around at least a portion of the smaller electrode, either the anode or the cathode, in the cell to define a supporting perimeter comparable to the perimeter of the larger electrode. The support layer generally comprises a polymeric material which helps to absorb pressures exerted on the cell layers during packaging. The anode, cathode, support layer and a separator layer placed between the anode and the cathode may be joined to form a battery. Preferably, a plurality of cells having the support layer may be joined to form a higher energy, longer life battery.

Battery cell having edge support and method of making the same

A backup power supply, comprising: a storage medium for holding an electrical charge and being configured to be connected and disconnected from an electrical device; a source of intermittent power coupled to a power supply and the electrical device being configured to provide an amount of power to the electrical device for a period of time long enough to connect the storage medium to the electrical device. An operating system for determining whether the electrical device requires power from the storage medium. In one embodiment the operating system monitors the current of the source of intermittent power and if the current exceeds a predetermined limit the operating system couples the storage medium to the electrical device by manipulating the position of a switching device disposed between the electrical storage medium and the electrical device.

Apparatus and method for providing temporary power

Described is a method and apparatus for determining the state of battery life of a starting, lighting and ignition (SLI) battery comprising; 1) determining the number of starting engine cranks the battery has performed and comparing that number with a desired number for starting engine cranks to ascertain a state of health of the battery, calculated as a percentage of the desired number; 2) determining the percentage of battery life diminished due to battery exposure to a maximum temperature and the minimum state of charge the battery has been exposed to at that temperature, calculated as a decrease from 100 percent; and 3) calculating the lower of the values of step 1 or step 2 thereby determining the state of the battery life.
