A battery cabinet or relay rack has provision for multiple tiers of batteries spaced so that batteries may be inserted in each tier. The batteries are supported by a tray or other structure so that they are positioned to permit top access to the battery terminals mounted on the front or front to surfaces of the battery. Tiers are positioned further from the front of the relay rack as the height of the tier increases. ## Claims ### Claim 1 An apparatus, comprising: a base; vertical metal supports extending from the base; a plurality of storage batteries; a plurality of horizontal metal supports attached to the vertical supports, the horizontal supports spaced vertically apart by at least a height of a storage battery of the plurality of storage batteries so as to accept the slidable insertion of individual batteries on a horizontal support of the plurality of horizontal supports; and a first restraining device is removably attached to the apparatus and located proximal to a front portion of the horizontal support of the plurality of horizontal supports; wherein the first restraining device corresponding to a first horizontal support of the plurality of horizontal supports and the first removably-attached restraining device corresponding a second horizontal support of the plurality of horizontal supports are spaced at consecutively increasing horizontal distances from a vertical plane coincident with a front-most portion of the apparatus, the vertical plane being defined over a height range corresponding to the plurality of horizontal supports; the apparatus further comprising: a second restraining device, disposed such that a horizontal distance between the first restraining device and the second restraining device is sized to accept a location of a storage battery of the plurality of storage batteries therebetween such that the storage battery is restrained from motion in a front-to-back direction. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the first restraining device is removably attached to a first horizontal support of the plurality of horizontal supports. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the second restraining device is fixedly attached to a same horizontal support of the plurality of horizontal supports as the removably-attached first restraining device. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the second restraining device is formed as a lip. ### Claim 5 (depends on 1) The apparatus of claim 1, further comprising: a plurality of cables, wherein electrical terminals of a group of storage batteries of the plurality of storage batteries are connected to form a series electrical string by cables of the plurality of cables. ### Claim 6 (depends on 5) The apparatus of claim 5, where a first series string and a second series string are connected in series by a cable of the plurality of cables. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the plurality of horizontal supports are horizontal trays each horizontal trays having a first restraining device. ### Claim 8 (depends on 7) The apparatus of claim 7, comprising at least three horizontal trays consecutively arranged with increasing distances from the vertical plane. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein electrical terminals of the storage batteries are positioned closer to a front of the apparatus than to a rear of the apparatus. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the plurality of horizontal supports comprise at least three horizontal trays, the horizontal trays consecutively arranged in height, with increasing horizontal distances from the vertical plane. ### Claim 11 A storage battery assembly for use in a back-up power supply, comprising: a plurality of storage batteries, each storage battery of the plurality of storage batteries having a pair of electrical terminals on a front portion of a top surface of the storage battery; a base; metal supports extending in a vertical direction from the base; at least three horizontal trays, each horizontal tray attached to supports of the metal supports, adjacent horizontal trays of the at least three adjacent horizontal trays spaced vertically apart by a height dimensioned to provide only sufficient clearance to accept slidable insertion of individual batteries of the plurality of storage batteries on a horizontal tray of the at least three horizontal trays; and a removably-attached first restraining device located proximal to a front portion of each horizontal tray of the at least three horizontal trays; wherein the removably-attached first restraining device corresponding to a horizontal tray of the plurality of horizontal trays and the removably-attached first restraining device corresponding an adjacent higher horizontal tray of the at least three horizontal trays are spaced at consecutively increasing horizontal distances from a vertical plane coincident with a front-most portion of the assembly, the vertical plane being defined over a height range corresponding to the at least three horizontal trays; and, a horizontal distance between front portions of the first restraining devices corresponding to adjacent horizontal trays is dimensioned to permit access to the pair of battery terminals of an inserted storage battery by a servicing tool from a location above the pair of battery terminals of the inserted storage battery on an adjacent lower horizontal tray of the at least three horizontal trays; and, a second restraining device, disposed such that a horizontal distance between the first restraining device and the second restraining device is sized to accept a location of the inserted storage battery of the plurality of storage batteries therebetween such that the inserted storage battery is restrained from motion in a front-to-back direction. ### Claim 12 (depends on 11) The assembly of claim 11, further comprising a second restraining device, disposed such that a horizontal spacing between the first restraining device and the second restraining device is sized to accept insertion of storage batteries of the plurality of storage batteries therebetween such that the storage batteries are restrained from motion in a front-to-back direction. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the second restraining device is formed as a lip. ### Claim 14 (depends on 11) The assembly of claim 11, wherein a second restraining device is fixedly attached to the apparatus. ### Claim 15 (depends on 11) The assembly of claim 11, further comprising: the plurality of storage batteries; and a plurality of cables, wherein electrical terminals of a group of storage batteries of the plurality of storage batteries are connected to form a series electrical string by cables of the plurality of cables.
