The recommended torque range for lithium battery terminals typically falls between 5 to 15 N·m (Newton-meters) for automotive applications, while larger industrial or solar batteries may require hi.
NOTE: Damage to terminals and/or batteries caused by under/over-torque is often unrepairable and is not covered under manufacturer warranty. Distributors or Dealers may offer replacement or repair, where possible, at the customer's expense. Recommended torque settings for terminal connections on Rolls batteries.
Why do you need a torque wrench for a nut & bolt?
This keeps the sharp edge from cutting through the plating, exposing the base metal, usually copper, to potential electrolyte attack and corrosion. When nuts and bolts are used, positioning of hardware should be such to facilitate access to the nut with a torque wrench. Hardware should be assembled manually, finger tight.
Calibrate the torque wrench before use to ensure accuracy. NOTE: Damage to terminals and/or batteries caused by under/over-torque is often unrepairable and is not covered under manufacturer warranty. Distributors or Dealers may offer replacement or repair, where possible, at the customer's expense.
What is a battery connector?
Connectors are frequently lead, tin, or nickel plated copper bus bars. They are fabricated as needed to meet the specific battery and it s application. Connectors also take the form of wire or heavy cable and are usually terminated with compression lugs.
What are the limitations of battery & connector design?
Limitations exist as a result of battery and connector design. It has been the author's experience that manufacturers frequently require periodic connection tightness checks to ensure a good connection. Measurement of connection resistance requires use of a micro-ohmmeter or other suitable low resistance measurement instrument.
What type of wire is used to connect a substation battery?
Small applications, such as a 50 amp hour substation battery are frequently interconnected with AWG #6 wiring. Where used, interaisle cables are usually the longest of the battery interconnections and are not normally supplied with the battery system.
