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: |

Customer Reviews
I ride a 2019 Harley Road glide special and in the past 2 years I have had bad experience with batteries, first one was a DIEHARD I brought from Advance Auto Parts, I got caught short in the mountains and needed a battery urgently, it lasted exactly ONE year before it died, when this happened my only option was to buy another as there was no other store nearby, again only lasted ONE year. When this died at traffic lights in rush hour I tried a battery from AutoZone, after fitting it in the store carpark I discovered it was DEAD, the store replaced it but I was never happy with it.
Then I purchased my first Big Crank and returned my existing battery to Autozone, this Big Crank has been perfect, I admit I have been keeping it on a tender as its been very cold even here in Florida and not rode much, but I have 100% more confidence I won't be let down without warning either in the mountains or at traffic lights in rush hour....
Final bonus, this battery was no more expensive than an inferior one from an auto store.
Very strong and built well
Just now needing to replace this USA made battery after 6 YEARS in my ‘05 FLHTI. It’s still working OK but charging slightly less than 100% so I’ll buy another battery from Battery Mart. Great service. Great product. Great prices.
