Appendix B - Terminal Connections
1. Remove any remaining factory-applied grease coating from the terminals with a
dry cloth.
2. Lightly brush the terminal, cable lug, terminal plates and contact surfaces with a plastic brush or
burlap.
3. Coat all electrical surfaces with NO-OX-ID grease. (Optional: Use heat gun or hot plate to melt and
then apply the NO-OX-ID grease, no open flames).
4. (Optional) - Re-flow excess NO-OX-ID with heat gun and wipe excess.
5. Install hardware and torque to 110 in. lb. (12.4 N-m).
6. Wash hands after working with lead.
Reworking Terminal Connections: If a terminal connection needs to be reworked (for any reason)
follow the below steps:
Once the battery string has been removed from service using properly insulated tools and all appropriate
battery safety methods remove the suspect connection(s).
1. Remove any existing grease using a dry cloth.
2. With a neutralizing solution consisting of one-pound baking soda mixed with one
gallon of water, wipe the cover and terminal seal area with a cloth moistened with the neutralizing
solution. Do not allow the neutralizing solution to enter the cell. Rinse with clear water and dry
thoroughly.
3. Lightly brush the terminal, cable lug or terminal plate contact surfaces with a plastic brush or
burlap, removing any oxidized or corroded areas.
Note: Liberty 2V batteries terminals, buss bars, cable lugs and terminal plates are made of copper and
have a thin layer of tin. Once the terminal connection is coated with protective NO-OX-ID type grease,
any “exposed”, or “un-tined” areas, no matter if from the factory or due to over brushing, will be protected
from oxidation by the grease and not require reworking. Optional: preheat the NO-OX-ID type grease and
apply warm. After working with any lead component, wash your hands.
4. Coat all electrical surfaces with NO-OX-ID grease. (Optional: Use heat gun or hot plate to melt
and then apply the NO-OX-ID grease, no open flames).
5. (Optional) - Re-flow excess NO-OX-ID grease with heat gun and wipe excess.
Re-Install hardware and torque to 110 in. lb. (12.4 N-m) and measure connection resistance.
