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!

Customer Reviews
Purchased this battery for my 2012 FXDB and it seemed to have plenty of cranking power. My Harley dealer told me that they were all about the same. For a hundred dollars I'll be happy if it holds up three years.
Used to replace the old battery on a 2000 Harley Dyna wide glide. More cranking amps than the stock one. Turns over and starts faster.
I love my MEGA CRANK BATTERY. Fit the Dyna perfectly.
Ordered a battery for my Harley Davidson. The battery fit perfect and was much less expensive and has better cold cranking than the original. Shipping was fast (2 days)
Great Harley replacement battery…
I always use these on my Dyna and Road King…they last just as long as the OEM HD….for half the cost you’d pay at the Stealership…
Highly Recommend!
Perfect fit.... no issues. Last time riding.. had a shifting linkage problem... so haven't rode the bike since. Bike started right up... No problem.
So far it"s working good. Highly recommend plus good fast service delivery. Thanks
