1. A battery kit system comprising:
- an assembly, comprising;
an enclosure having a first terminal and a second terminal configured to couple to a load;
a plurality of battery cells configured to be disposed within the enclosure and electrically coupled to the first and second terminals by a first switch, and wherein the first switch is capable of closing a first circuit between the plurality of battery cells and the load;
an ultracapacitor configured to be disposed within the enclosure and electrically coupled to the first and second terminals by a second switch, wherein the ultracapacitor is arranged in parallel to the plurality of battery cells, wherein the second switch is positioned in parallel to the first switch, and wherein the second switch is capable of closing a second circuit between the ultracapacitor and the load;
a DC-DC converter configured to be disposed within the enclosure and electrically coupled to the plurality of battery cells and the ultracapacitor;
a plurality of sensors configured to be disposed within the enclosure and to measure at least one parameter of the plurality of battery cells, the ultracapacitor, or a combination thereof; and
control logic configured to be disposed within the enclosure and to control the DC-DC converter and the first and second switches and programmed to meet a power demand of the load based on the at least one parameter by;
calculating a rate of change of the at least one parameter with respect to time;
comparing the rate of change to a preset threshold; and
controlling the first and second switches based on the comparison of the rate of change and the preset threshold; and
at least one adapter that adapts the enclosure for mounting in place of a lead-acid battery comprising one or more lead-acid electrochemical cells without an ultracapacitor and having a standard form factor.

Abstract
A battery system includes an enclosure conforming to a standard form factor, such as a group specified by the Battery Council International. A battery and at least one ultracapacitor are disposed in the enclosure and interconnected to provide electrical energy at battery terminals. Control and/or regulation circuitry may also be provided in the enclosure and interconnected with the battery and ultracapacitor. The battery system may be designed to retrofit existing batteries, such as in vehicular and other applications. The use of a standard form factor allows for little or no alteration of the physical and electrical systems into which the battery system is placed.
