Tech Tip: Easy Front Mount Installations
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 front 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. How A Front Mount Looks when Installed: |

Battery arrived with full charge, what more can you want
Batterymart always has the items I need. I have purchased several battery’s from them for my stable of bikes. They are always fresh and ready to go.
I replaced a Harley Battery on an FLHRCI with the Big Crank. Very fast delivery from Battery Mart. Arrived charged. It fit perfectly. I didn't have to use the height spacer. Nor did I have to use the washer spacers since mine is a top-post configuration. It continues to crank this big motor over.
Great for a high compression engines, turns over without problems.
Received battery within 5 days because it was a weekend. Fit perfect charged and ready to go.
