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
Purchased this battery to replace a weak battery in my Harley Softail.
Delivery was fast and the price was much better than the dealership.
The battery was easy to install and works great!

I have been using these batteries for years. I have 4 Harleys, and Harley dealers want $180 or more for batteries that last 4 years. The Megas are cheaper, and last every bit of 5 years or more.
Recommend battery
I have a couple of Harleys. One gets ridden almost daily, some get occasional use, and some get rare use.
I have been using Battery Mart batteries exclusively for well over a decade. The prices are great, the 2-day shipping has been convenient several times, and the batteries are the best and longest lasting, and deliver the consistently best power of any Harley battery I have ever used.
As stated in the title, I recently have purchased the imported Mega Crank battery instead of the USA made Big Crank due to immediate need and the Big Crank being backordered. Reviews suggested similar satisfaction with these, and they cost a bit less. Time will tell. All things being equal, I would buy the Big Crank due to my long experience with them.
I have recommended Battery Mart batteries to all my riding family and friends. Many have bought from them, some are repeat customers, and all are well satisfied.
Fast delivery and an Awesome Battery ! Will order right here again
Starts my canam 1000 right up.
This is my second Mega Crank. The other one lasted me 6 years! I put it on a battery tender once a week for a day. This is for a built 103 Harley! Cranks over great! Highly recommend!
