Notes:
1.

For information on racks, see brochure 12-560.

 
2.
Rack lengths for other than 60-cell batteries can be calculated by the formula: Number of cells per tier or step x (L + 0.5) - 0.5 = total rack length.
(Where "L" is length of cell.) Where dimensions are critical, check with C&D engineering.
 
3.
Rack width does not include thickness of crossbracing; increase width by 0.5 in. (12.7 mm) for crossbracing when this dimension is critical.
 
4.
Height measured from base to top terminal of upper tier battery.
