EXIDE-IRONCLAD BATTERIES

H

cient power and stamina to handle the job in a steel mill ? Part o f the answer lies in the size o f the material handling units available today and already in widespread use— ranging up to 3 0 ,0 0 0 lb. capacity. For these units you can get Exide-Ironclad Bat­

teries that have a giant surplus of power exceeding any requirements they will ever be called on to meet.

Experience in the largest plants is demon­

strating every day that the Exide-Ironclad is the right battery for this job. N ot only

does it provide a tremendous reserve of power for unusual loads and grades, but its performance remains good to the end of a working shift. That is because it main­

tains a good voltage, hour after hour, dur­

ing its period o f discharge, assuring corre­

spondingly high vehicle speeds at all times.

Exide-Ironclads are long-lasting. Com ­ bined with their notably low cost of main­

tenance, this means a consistent saving.

Let Exide-Ironclads improve your material handling service and cut costs. Write for new, free booklet, “ Battery Handling Sys­

tems and Equipment.”
