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
Just replaced the original 6 year old battery in Road Glide Ultra. I have no complaints getting 6 yrs of life out of the factory. Purchased Big Crank after reading so many positive comments in a couple HD forums. I had forgotten how easy the bike can start. Not as satisfying as a new set of tires, still very comforting to know the bike will start when you push the GO button.
Highly recommend Battery Mart. Fast shipping, good pricing and right product for the task.
I needed a new battery for my Harley touring bike and came across the Battery Mart website and found I liked what it said and also that it had just what I needed at a lower price than my local car part dealer so I ordered one and it came fast and was just what I needed. So far it has been perfect and I love the way the motor spins up for the start.
All is good. Replaced a 4 year old battery in my Road King just because. I figured 4 years is the limit even though my old battery was working fine. The best part is Big crank is made by East Penn which also makes Deka and Duracell and it is the only manufacturer I will buy and I have never been let down. East Penn also makes Harley Davidson batteries and there you will pay $50 higher just because it says Harley Davidson.
I have bought several of these for my Harleys and they have worked great
The battery came from batterymart packed perfect. The fast shipping even made it a bonus! The battery came as specified in their description.
This battery replaces an unusual group 151 battery that isn't manufactured in an AGM unit only SLA. The Big Crank fires right up. Has more CCA and reserve
power than my oem Honda battery. This one is legit
Great battery choice with free 2 day delivery
I ordered my battery online and it was quick and easy. The day after I put my order in, I thought that I had ordered the wrong battery. A quick call to them and they confirmed that the battery that I had ordered was the correct battery. A few days later my new battery was delivered and fit perfectly into my Harley. I have 3 motorcycles and this is the 5th battery that I have ordered from them over the last 10 years and I will continue to shop at Battery Mart!
