Description

BACKGROUND OF DISCLOSURE 1. Field of Disclosure This disclosure is directed to uninterruptible power supplies (UPSs), and more particularly to an external battery that is releasably connected to the UPS. 2. Discussion of Related Art A typical UPS, indicated at 2 in FIG. 1A, is configured with components of the UPS and with a replacement battery cartridge that can be installed within the UPS. With the advent of ultra-high frequency and dual active bridge DC-DC power conversion topology and DSP control technologies within UPSs, the need to reduce the number and size of components is desired. This reduction in the number and size of components enables the shortening of an overall UPS chassis dimension. External batteries can be connected to the UPS to extend a run time of the UPS. A modified UPS, indicated at 4 in FIG. 1B, in one exemplary embodiment, has a chassis of the UPS 4 reduced from a width of 641 millimeters (mm) to 450 mm, which is a 31% reduction in depth. Due to the short chassis depth, the size of a battery cartridge 6, e.g., a lead-acid battery cartridge, is reduced. The reduction in size of the UPS 4 and the battery cartridge 6 lessens run time of the UPS 4. SUMMARY OF DISCLOSURE One aspect of the present disclosure is directed to a battery cartridge assembly configured to be positioned behind a UPS having a back side facing a first direction. In one embodiment, the battery cartridge assembly comprises a housing having a front side and a back side.
