A retractable battery tray includes a supporting structure, a tray assembly, and a heating device. The support structure of the battery tray generally spans and attaches to two spaced apart supporting base structures of a telecommunications equipment cabinet and supports the tray assembly therebetween. One or more batteries are supported and carried on a tray member of the tray assembly and vertically ganged heavy-duty horizontally extending slide rails movably attach the tray member to the support structure. A closure panel attaches to the spaced apart supporting base structures to retainably conceal the tray in a retracted position. Positioned in the tray underneath the battery, the heating device includes a thin sheet-like heating pad sandwiched between a protective plate therebelow and an insulating sheet thereabove. The insulating sheet retains heat from the heating pad within the tray. The protective plate prevents the batteries from damaging the heating pad.
An equipment cabinet for use in housing telecommunications equipment including outside plant communications equipment, said cabinet including two pedestal portions and an enclosure portion positioned on and extending between the two pedestal portions, said pedestal portions and said enclosure portion defining a space, a battery tray apparatus being movably retrained in said space, said battery tray apparatus comprising:
An equipment cabinet comprising a movable battery tray apparatus which movably positions at least one relatively large back-up battery relative to telecommunications equipment retained in a protective cabinet, operation of said telecommunications equipment in the absence of a primary power source being facilitated by back-up power supplied by said battery;
