Appendix A - Connections
A.1 Terminal Connections
1. Remove any remaining factory-applied grease coating from the terminals with a
dry cloth.
2. Lightly brush the terminal, cable lug and terminal plates contact surfaces with the supplied
brass bristle brush or scotch brite type pad.
3. Coat all electrical surfaces with NO-OX-ID. (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 160 in. lb. (18 N-m).
6. Wash hands after working with lead.
A.2 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 sodium bicarbonate 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 the supplied brass
bristle brush or Scotch brite™ type pad removing any oxidized or corroded areas.
4. Coat all electrical surfaces with NO-OX-ID. (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 with heat gun and wipe excess.
6. Re-Install hardware and torque to 160 in. lb. (18 N-m) and measure connection resistance.
If still > +10% consult C&D.
NOTE:
The ATP and ATLP msEndur II series of batteries terminals, bus bars, cable lugs
and terminal plates are made of copper and have thin layer of either tin or lead.
Once the terminal connection is coated with protective NO-OX-ID type grease,
any “exposed”, “un-tinned” or “un-leaded” 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.
