Preparing and Installing Connections
The cells are now positioned and ready to be connected.
7.4.1 Terminal
Posts
All terminal posts of the cells are greased at the factory to prevent oxidation.
1.
Inspect each terminal post. If discoloration or tarnishing is noted, neutralize the post with
sodium bicarbonate and water solution (Section 12.1.2, Procedure 2). Dry thoroughly.
2.
Clean the contact surface with a stiff-bristle nonmetallic brush/pad until a clean, bright
surface is obtained.
3.
Apply a light coat of NO-OX-ID grease.
7.4.2 Intercell
Connectors
1.
The connections are made by bolting the supplied connectors/cable assemblies to the cell
posts of opposite polarity on adjacent cells or batteries. When more than one cable for
each cell is furnished, bolt the cable to the posts in the identical position on each battery.
2.
With a small paintbrush, apply a light coat of heated NO-OX-ID grease to the contact
surface of the terminal post.
3.
Place cable lug directly on lead terminal surface. Use supplied ¼-20 bolts and washers to
fasten cable to terminals. Secure all connections finger-tight to allow for some adjustment
of position.
4.
After all connections are completed, torque all stainless steel connector bolts to 70-75
inch-lbs (8.0-8.5 Nm).
5.
Apply a light coat of heated NO-OX-ID grease to the bolted connection with a small
paintbrush in the area of the terminal post only. Ensure the entire cable lug and stainless
steel bolt are coated.
Before preparing and making the connections,
heat NO-OX-ID grease in hot water as necessary
to soften for application with a paintbrush.
WARNING
Make sure that all bolted battery connections are torqued to the
recommended values. The increased resistance of a loose
connection can generate heat and become a fire hazard.
