Tech Tip

This battery is supplied with unique terminal hardware (2 spacers and 2 bolts for cable to terminal connection). This hardware is required for proper installation on certain applications. Other hardware may damage terminals and should not be used. The spacers are required for side mount cable installation only! The top mount position does not require the round spacers, use supplied bolts only. Torque bolts to 6 to 8 ft. lbs.

Good Connection: With the spacer, there is a flat, flush connection between the battery terminal and the cable. This connection will ensure you receive full cranking power.	Bad Connection: Without the spacer, the cable does not make a flush connection, creating a gap. This will reduce your cranking power, cause arcing, and will melt your terminals.
