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
Better than any polaris battery I have bought for side by side
Arrived fully charged. Bike started right up. Hope to get many years of use out of it!
Big Crank batteries are a great value.
I also have one in my 1979 Honda CBX.... Always have it on a mainter charger... Been in for over 10 years.. still starts like new..
So why does it matter that it has been a year? Here's why. For the last few years, I have had to buy a new battery for my motorcycle each year. The original battery lasted about 10 years. I then bought 3 from a big-name auto parts store. The first one lasted 2 years, the next 2 each lasted a year. Recharging them did not work. And yes, I was buying and paying good money for the "good" batteries. I was done, I'd had enough. So, last year, I bought this battery. I had nothing to lose anymore. So the true test was not would this battery work when I first bought it, but would it make it to the next year. Well, after sitting all winter, on this nice Spring-like day, I thought I'd try to fire the bike up and see what would happen. Without a hesitation, this battery turned right over and it started right up. This battery is already better than those big-name store batteries. So yes, I would highly recommend!!! And to boot, the service here is great, it was shipped to me in no time!!!
got here fast , fit just right
