`ABSTRACT
`A switchable direct current voltage power supply for pow
`ering a device having an uninterruptible power supply with
`additional standby power capacity where the switching
`power supply has a power input and a power output for
`powering a device with a first battery pack attachable to the
`switching power supply for providing power to the device
`when the power input fails and a second battery pack
`attachable to the first power supply providing additional
`standby power capacity and where the attachable battery
`pack utilizes lithium chemistry .
