6.6 Terminal Plates
(If part of the battery system)
For reasons of safety, it is recommended that terminal plates be installed before connector
installation as described in section 6.8. Interconnect cells and modules with tin-plated (standard)
copper connectors and 6mm stainless steel hex head bolts and washers in accordance with the
connection diagram supplied with each battery shipment.
Prior to installation, lightly brush (with a plastic brush or burlap) the battery terminals and terminal plate
contact surfaces. Then apply a thin coating of NO-OX-ID type grease. The Liberty 2V battery terminals
are made of a brass alloy with a tin coating cast inside a lead terminal. Terminal plates are made of
copper with a thin tin coating. Once coated with protective NO-OX-ID type grease, any “exposed”, “un-
tinned” areas, no matter if from the factory or due to over brushing, will be protected from oxidation by
the grease thus not require reworking. Optional: preheat the NO-OX-ID type grease and apply warm.
After working with any lead component, wash your hands.
6.7 Numbering Cells
For ease of identification and for record keeping, all cells of a battery should be numbered. Plastic
peel-and-stick numbers are furnished in the accessory kit. Common practice is to start with “1” on the
cover of the incoming (+) positive terminal of the battery and follow the electrical circuit with
succeeding numbers on the cell covers.
6.8 Interconnection
Cell series connection is made from the (+) of one cell to the (-) of the next sequential cell. It is essential
that the cell location and orientation match the included drawing. All connections must be made as
indicated on the drawing with no deviations. If no drawing is provided or it is lost, contact C&D before
making any connections.
The cells ship with NO-OX-ID grease applied by the factory to the terminals, however it may be
necessary to rework prior to connecting the cells with the supplied inter-cell connectors. Refer to the
Appendix for additional instructions for reapplying NO-OX-ID grease.
Prior to installation, lightly brush (with a plastic brush or burlap) the battery terminals and any contact
surfaces of the inter-unit connections. Then apply a thin coating of NO-OX-ID type grease to both the
battery terminals and contact surfaces of the inter-unit connectors prior to installation. The Liberty 2V
battery terminals are made of a brass alloy with a thin tin coating cast inside a lead terminal. The inter-
unit connectors (cables and bus bars) are made of copper and have a thin lead or tin coating. Once
coated with protective NO-OX-ID type grease, any “exposed”, “un-tinned” coated areas, no matter if from
the factory or due to over brushing, will be protected from oxidation by the grease thus not require
reworking. Optional: preheat the NO-OX-ID type grease and apply warm. After working with any lead
component, wash your hands.
