C&D Technologies RS-1476 Standby Battery Vented Cell - Manual (Page 12)

DO NOT REMOVE LEAD PLATING
To maintain electrical contact integrity, C&D supplies NO-OX-ID grease (in the accessories package) as a
corrosion resistant coating for all bolted electrical contacting surfaces. For optimum connection integrity, C&D
recommends the following procedure:
Cell posts are typically factory coated with either NO-OX-ID grease or oil in the factory and may be covered with a
plastic cap to prevent oxidation of the lead during transportation and storage.
1. Remove any factory-applied coating from the posts and post seals with a dry cloth as they may be
contaminated with dirt or residual acid. NOTE: Post seals may appear wet due to the oil.
2. With a neutralizing solution consisting of one pound sodium bicarbonate mixed with one gallon water, wipe the
cover, post and post seal with a cloth or fiber bristle brush moistened with the neutralizing solution. Rinse with
clean water and dry thoroughly. DO NOT USE ANY INDUSTRIAL BATTERY CLEANERS AS THIS WILL VOID
WARRANTY!
CLEANING OF BATTERIES WITH WATER OR ISOPROPYL ALCOHOL ALONE WILL NOT NEUTRALIzE ACID.
3. Lightly brush the post and lead ring of the post seal with the plater’s brass brush (provided in the accessories),
or medium grade Scotch Brite™ to provide a clean bright finish. NEVER USE STEEL BRUSHES OR OTHER
ABRASIVE TOOLS OR MATERIALS. Cells designed for high discharge currents are constructed with tin flashed
copper inserts cast within the lead posts to optimize conductivity. The copper faces should be lightly brushed to
minimize scratching or removal of this tin flashing.
Note: Incidental copper exposure on posts due to handling and installation will neither degrade battery
performance nor reduce the battery’s expected operating life when properly maintained.
4. Carefully remove any oxidation or white powder from the inter-cell connectors’ mating surfaces with either
the plater’s brass brush, fiber bristle brush, a piece of burlap cloth, or medium grade Scotch Brite™ and buff to
a clean and uniform finish. Inter-cell connectors are lead plated copper and require that care be taken not to
remove the plating.
5. Heat the NO-OX-ID grease to a cream like consistency using a thermostatically controlled hot plate (with no
open flames). Set the temperature between 160°F (71°C) to 185°F (85°C) to maintain the desired consistency.
NO-OX-ID grease must be applied to the terminal post and to the horizontal lead surface of the post seal to
ensure all exposed lead is properly coated to protect against surface discoloration.
Apply a thin coat of grease to each end of the inter-cell connectors (where they will
make contact with posts). On four and six-hole connectors, use a one-inch paint brush to
apply NO-OX-ID grease to both sides of the middle holes and to cell posts. To achieve a
continuous film of protective NO-OX-ID grease finish the completely assembled battery
with a hot air gun or blower. Wipe any excess NO-OX-ID grease from the cover(s).
4.7 Making the connections
C&D batteries are supplied with stainless steel connecting hardware; optional lead-brass
hardware is available (see Figure 1.4.5 & Table 3).
Cells are supplied with different post configurations suited to their current handling requirements, see Figure 1.4.6.
Place inter-cell connectors against cell posts and insert C&D supplied brass stud or stainless steel bolt through
the bolt hole in the post and the hole in the connector. For stainless steel bolts, install heavy-duty washers, bolts
and nuts. Ensure the sharp edge of the stamped steel washer is facing away from the inter-cell connector. Hand
tighten. Where one brass stud and two lead capped nuts are supplied, be sure that an equal number of threads is
engaged on each nut.

CAUTION
If the hot plate does not have a thermostatic control, exercise extreme care to
avoid overheating the grease and causing a fire. Do not use open flames.
NO-OX-ID grease has a minimum flash point of 450°F (232°C).
