Enter the desired type and number of tiers. This selection may depend on space available, but should not exceed

two tiers. Step tiers are preferable for ease of maintenance, provided space is available. The maximum

acceptable height of the racks is usually 50 inches (1.2 m) from the floor to the top of the battery jar located on

the second tier. For racks greater than 50 inches (1.2 m) in height, contact the local authority having jurisdiction,

as these become a problem for the following reasons:

Difficult and unsafe to maintain

Temperature differences between cells

Seismic integrity (where applicable)

********************

a. Provide battery racks made of steel, properly insulated and coated in
