Place the cells on the rack and make sure that the spacing allows the accommodation of the supplied inter-cell
connectors (approximately 0.4”). Most batteries have cells connected in a simple series arrangement, so the cells
should be arranged to preserve the polarity sequence.
I.e. , (+)…(-)…(+)…(-)…etc.
NEVER LIFT CELLS BY THE TERMINAL POSTS. ALWAYS USE APPROPRIATE DEVICES (SUCH AS
LIFTING STRAPS AND SUITABLE MECHANICAL EQUIPMENT) TO PREVENT INJURY TO
PERSONNEL OR DAMAGE TO THE CELLS.
For batteries to be installed on multiple tiers, start by placing the cells on the lower tier on either side of the frame
where the stand sections meet. Any unused stand space should be on the upper tier.
For batteries on stepped racks, leave any unused space on the back (top) step.
Where multiple racks are arranged end-to-end, adjust the position of the adjacent end cells to accommodate the
flexible inter-rack connectors supplied.
Take particular care to preserve the positive to negative sequence when using flexible inter-tier, inter-step or inter-
rack connectors between rows of cells. Leave the main positive and negative terminals of the battery free for
connection to the charger and loads.
Check cell alignment.
Prepare the inter-cell connectors by lightly abrading the contact surfaces with a fine grit abrasive paper. Do not
use a wire brush and be especially careful not to break through the lead plating.
Apply a light coating of no-oxide grease to the contact-making areas of each connector. This is best done by
carefully melting the grease and dipping connector ends (it is unnecessary to coat the central part of the
connector).
Fit the inter-cell and inter-tier connectors using the bolts, nuts and washers supplied. Before assembly, lightly
smear no-oxide grease on the surfaces of all hardware.
Use insulated wrenches or sockets to tighten the parts firmly together (see the table below for torque settings).
BLSe block batteries 6V - 12V 70 inch pounds (8 Nm)
LSe cells 2V 90 inch pounds (10 Nm)
Pay special attention to avoid short-circuiting the cells with any of the battery hardware.
Check tightness and cleanliness.
Make sure that all vent caps are closed.
Connect the positive terminal of the battery to the positive terminal of the charger and the battery negative to the
charger negative.
Number the cells with the numbers supplied with the battery. It is common practice to number the cells beginning
with #1 at the positive end of the battery and following the sequence of electrical connection of the cells to the
negative end of the battery.
8.0 Charging
8.1 Initial Charge of Dry Cells
An initial or freshening charge must be given to all batteries before being put into service. This is
most important for cells supplied in dry charged conditions and filled on site.
