type PH battery is a complete unit, sealed in a glass
jar. The cells are to be placed side by side on the battery rack so
that the positive terminal of one cell (long connecting strap) can be
connected to the negative terminal (short strap) of the adjacent cell.

Join the positive terminal of one cell to the negative terminal of the
adjacent cell and continue this procedure until all the cells are
connected together. This will leave one positive and one negative
terminal of the battery to be connected respectively to the positive
and negative wires from the switchboard. The bend in the top connector
should be made about one inch above the pillar post to eliminate the
danger of breakage at the post.

In tightening the bolts do not use excessive force, as there is
liability of stripping the threads.

Give the battery a freshening charge before it is put in service. Type
PH cells have a gravity of 1.250 when fully charged, and 1.185 when
discharged.
